The Ultimate Guide to Choosing a PSAM Myers Pump

Introduction: When Your Water Stops, Every Minute Matters
The shower goes cold, the pressure drops to a whisper, and within seconds the house is silent. No water for coffee, chores, or flushing. That’s how most well pump calls begin. In rural homes, a failed pump isn’t an inconvenience—it’s a full stop. Average households need 8–12 GPM at 40–60 PSI to live normally. If your pump can’t meet Total Dynamic Head (TDH) or stalls under load, you feel it immediately: sputtering faucets, cycling pressure switches, scorched motors. A properly sized, well-built pump should run 8–15 years. Many don’t because of weak materials, poor staging, or sloppy installs.

Meet the Castrillo family of Deer Lodge Valley, Montana. Raul Castrillo (41), a high school science teacher, and his spouse, Mireya (39), an ER nurse, live on 12 acres with their kids, Nico (11) and Lila (8). Their 220-foot private well had a 3/4 HP budget submersible rated at 10 GPM. After three summers of grit intrusion and a pressure tank undersized at 20 gallons, the Red Lion unit cracked at the discharge after a pressure spike. No water for 36 hours, livestock troughs empty, laundry piling up. Raul called PSAM. We sized their system, switched them to a Myers Predator Plus Series 1 HP submersible with Teflon-impregnated staging, and added a proper pressure tank. Their volume stabilized, and the motor runs cool—even on irrigation days.

This list lays out what matters when selecting a PSAM Myers pump, whether you’re rushing an emergency replacement or planning a proactive upgrade. We’ll cover stainless steel construction, Pentek XE motor advantages, 2-wire vs 3-wire configurations, GPM and TDH sizing, warranty value, field serviceability, installation best practices, and backup options. Contractors get pump curve clarity; homeowners get straightforward answers; emergency buyers get fast-ship options ready to drop in. If your goal is steady pressure, lower power bills, and a pump that just runs, you’re in the right place.
#1. Myers Predator Plus Series Stainless Steel Construction - 300 Series Lead-Free Metals for 8–15 Year Lifespans in Private Wells
A pump living 200+ feet below grade battles minerals, acidity, and constant pressure cycling. Material choice decides whether you’re replacing in three years or bragging at fifteen.

Myers builds the Predator Plus Series with 300 series stainless steel for the shell, discharge bowl, shaft, coupling, wear ring, and suction screen. That’s not marketing fluff. Stainless resists chloride pitting and acidic well chemistry that will eat cast iron stages and cheap fasteners. With stainless flow paths and a close-tolerance engineered composite staging, you get corrosion resistance and dimensional stability—key to holding efficiency as the pump ages. Lead-free construction meets modern safety expectations and avoids galvanic headaches when paired with stainless drop pipe and brass pitless fittings.

The Castrillos’ old thermoplastic housing deformed after pressure spikes and heat soak from short-cycling. With the stainless Predator Plus, we matched their TDH at 220 feet plus 60 PSI (approx. 260–280 feet TDH) and selected a model that keeps the impeller stack in its Best Efficiency Point (BEP) at 10–12 GPM. Their pressure recovered and stays consistent at 50 PSI cut-in to 70 PSI cut-out.
Corrosion Resistance in Real Water
Mineral-rich water and low pH chew through mixed-metal pumps. 300 series stainless steel does not. In lab tests and in the field, these stages hold edge sharpness and balance, preserving 80%+ hydraulic efficiency near BEP. You’ll notice lower amperage draw on your 230V circuit and fewer nuisance trips.
Lead-Free, NSF Mindset
Modern homes expect water-contact components to be safe. Myers’ lead-free stainless build complements NSF expectations and aligns with UL/CSA certifications. For families like the Castrillos with kids, that peace of mind matters as much as pressure.
Wear Ring and Suction Screen
A stainless wear ring maintains tight clearances between impeller and diffuser—critical to preventing recirculation losses. The stainless screen resists denting during install and protects against coarse grit entry, extending impeller life.

Key takeaway: choose stainless where it counts. Myers’ build quality is quiet insurance against the very conditions that kill lesser pumps.
#2. Pentek XE High-Thrust Motor Technology - Cooler Running, Lower Amps, and Thermal/Lightning Protection for Continuous-Duty Wells
Power is nothing if it cooks itself in August. The Pentek XE motor on Myers Predator Plus pumps is engineered for high-thrust, continuous duty performance—with thermal and lightning protection built in.

At depth, submersibles need thrust bearings that carry axial load from stacked impellers. Pentek XE motors use heavy-duty thrust assemblies and optimized windings to hold efficiency under head. Thermal overload protection shuts the motor down if voltage sags or a hydraulic issue causes overheating. Lightning protection gives a fighting chance against summer storms—especially in open valleys like Deer Lodge. Combine that with strong insulation on stator windings, and you get a motor that doesn’t give up when conditions turn rough.

Raul’s system saw short-cycling from an undersized tank, which beats a motor to death. After moving to the Pentek XE 1 HP, amperage normalized, heat soak subsided, and starts per hour dropped under my target of 6–10 for residential systems.
Thrust Bearing Matters
High-thrust bearings absorb the load from multi-stage impellers at pressure. The Pentek XE motor keeps shaft axial play tight, which prevents rotor-to-stator rubbing and extends seal life. That’s how pumps survive heavy irrigation days without noise or vibration.
Thermal Overload & Lightning Protection
Built-in thermal cutouts respond to abnormal heat, and surge suppression helps during storms. On remote services, I still recommend a panel-mounted SPD and a grounded well cap—cheap insurance for sensitive electronics.
Cooler Operation = Longer Life
Efficient windings plus lower slip minimize wasted heat. Less heat means less varnish breakdown on windings and fewer seal failures. In the Castrillo home, we saw cooler motor temperatures even after 45 minutes of continuous watering.

Bottom line: Myers paired with Pentek XE runs cooler, safer, and longer. That’s the foundation of any dependable residential well water system.
#3. Teflon-Impregnated Staging - Self-Lubricating Composite Impellers That Laugh at Grit and Sand
Nothing chews up a pump faster than sand. The fix isn’t hoping for crystal-clear water; it’s choosing impellers that can live with grit. Myers uses Teflon-impregnated staging with self-lubricating impellers that resist abrasion and don’t gall when particulates sneak through.

In deep wells, small solids make it past the intake screen. Traditional thermoplastic impellers wear their edges down, increasing slip and dragging efficiency off a cliff. The Myers engineered composite keeps its geometry, preserving pressure and flow longer. The material’s lubricity prevents heat build-up during micro-contact events, and in my teardown inspections, these stacks show less scoring after years in marginal wells.

At the Castrillos’ site, fine silt would pass a standard intake. Their old pump’s impeller edges rounded off within two seasons. The Predator Plus held pressure after a full summer—no drop in shower performance, no “weak sprinkler” effect.
Grit Happens—Design for It
No well is perfectly clean forever. Engineered composite impellers with Teflon-impregnation tolerate grit better than plain thermoplastic. That’s the difference between 5-year disappointment and decade-long service.
Stable Clearances
Maintaining diffuser-to-impeller clearance helps keep your pump near BEP. It’s why pressure tanks don’t short-cycle and why you don’t hear your pressure switch click on and off at dinner.
Lower Wear Means Lower Bills
As impellers wear, motors pull more current to maintain pressure. Preventing that wear saves electricity and reduces breaker trips. Efficiency is not a brochure metric—it’s your monthly bill.

Pro tip: if your water tests show sand or silt, add a torque arrestor, cable guards, and ask PSAM for a screen sizing recommendation. Then pick the Myers staging that can take a beating.
#4. Extended 3-Year Warranty Coverage - Industry-Leading Protection That Lowers Lifetime Cost 15–30%
Warranties aren’t decorations; they’re confidence measured in months. Myers backs Predator Plus submersibles with an industry-leading 3-year warranty, while many peers stick to 12–18 months. If you want real lifetime value, this matters.

Manufacturers don’t offer extended coverage on components that fail often. Myers covers manufacturing defects and performance issues, validating their stainless construction, motor quality, and staging design. Over a decade, that extra 18–24 months of coverage translates to tangible savings and less downtime. In rural life, downtime means hauling water or roughing it—both are bad options.

When I registered the Castrillos’ install through PSAM, they received proper documentation and support numbers. It’s a small step that creates peace of mind when storms roll through or a power event happens.
Coverage Scope that Counts
The 3-year warranty gives you breathing room through the early years when manufacturing defects would surface. Pair it with PSAM’s tech support and you’ve got a safety net, not a hope.
Warranty and Proper Sizing
Manufacturers analyze returns. Properly sized pumps run cooler and live longer; improperly sized pumps cook. Our curve-based sizing protects warranty and performance—two birds, one stone.
PSAM Registration and Support
Fast shipping is great. Faster support is better. Keep your serials and install notes; PSAM helps streamline claims if you ever need them.

Call it insurance without the premium. Long coverage plus proven durability is why I put Myers on my “Rick’s Picks.”
#5. Best Value 2-Wire Configuration - Simplified Installation Saves $200–$400 vs Complex 3-Wire Systems
Upfront cost and future service both hinge on wiring choices. For most residential wells, a 2-wire well pump offers the cleanest install and lowest cost. Myers Predator Plus supports both, but when conditions allow, 2-wire shines.

A 2-wire motor integrates the start components internally—no external control box to mount, no extra wiring run. You save on parts and labor. With fewer connections, there’s less to corrode in a damp basement and fewer failure points. Reliability improves because there’s simply less to fail. On a 230V single-phase circuit, many 1/2–1 HP applications run beautifully in 2-wire with predictable starts and smooth operation.

For Raul’s 1 HP requirement at 220-foot static depth, we evaluated voltage drop, amp draw, and start torque. His wire gauge was appropriate, and irrigation duty cycles didn’t demand external controls. Result: we chose 2-wire—less clutter, lower cost.
When 2-Wire Wins
If your TDH and HP fall in the sweet spot (1/2–1 HP, typical residential TDH), 2-wire simplifies everything. No external control box, fewer splices, quicker troubleshooting.
When 3-Wire Makes Sense
Above 1 HP, or with very deep wells, 3-wire can provide serviceable start components and diagnostic ease. Myers offers both, so pick based on TDH and service goals.
Check Voltage Drop
Long runs can starve motors. Verify amperage draw myers grinder pump https://www.plumbingsupplyandmore.com/submersible-well-pump-rustler-series-1-stage-1-2-hp-8-gpm.html and wire gauge for your 230V circuit. PSAM provides wire size charts—use them.

My rule: keep it simple if the application allows. Myers gives you both options, and PSAM helps you pick the right road.
#6. Well Depth and GPM Sizing Requirements - Matching Horsepower to Demand Using Pump Curves and TDH Math
Wrong size is the fastest way to kill a good pump. Proper selection uses the pump curve and your TDH. Skip either and you’ll pay for it.

Total Dynamic Head = static water level + drawdown + friction loss + desired pressure (converted to feet: PSI × 2.31). Once you know TDH and flow demand (usually 8–12 GPM for a home, more for irrigation), you pick a pump where your operating point sits near the BEP on the curve. That’s where efficiency is highest and life is longest. Oversize and you short-cycle; undersize and you starve fixtures and overheat.

For the Castrillos: static level around 130 ft, pump set at 195 ft, desired 60 PSI (138 ft), 10–12 GPM demand, with friction losses ~12–18 ft. We landed around 280–300 ft TDH at 10–12 GPM—square in Predator Plus 1 HP territory with adequate staging.
Horsepower vs Stages
More stages equal more head. 1/2 HP handles many 100–150 ft wells at 7–10 GPM. 1 HP handles 200–300 ft TDH at 10–12 GPM. Deep or high demand? Move to 1.5–2 HP.
Friction Loss Counts
Don’t ignore long myers deep well pump https://www.plumbingsupplyandmore.com/plumbing-hvac-brand-categories/myers-pumps.html runs, elbows, and undersized pipe. A 1–1/4" trunk line and 1-1/4" NPT discharge reduce losses and keep the curve honest.
Pressure Tank Sizing
Tank size controls cycling. Target 1–2 minutes of runtime per cycle. A 44–86 gallon tank pair well with 1 HP systems; small tanks kill motors and controls.

PSAM will run the numbers with you. Get TDH and curve right, and your Myers submersible well pump will sing.
#7. Field-Serviceable Threaded Assembly - Repairs Without Pulling the Entire System Mean Faster, Cheaper Fixes
Serviceability doesn’t get enough attention—until something goes sideways. Myers uses a field serviceable threaded assembly that speeds repairs and avoids unnecessary replacements.

Threaded bowls and stack components let a qualified pro swap worn stages or replace a check without scrapping an otherwise healthy unit. When parts are modular and accessible, you save on labor—especially on farms or cabins where mobilization costs add up. I’ve kept years-old Myers pumps in service with an afternoon on the tailgate and a parts kit.

When Raul needed a new check valve up top, we verified the internal check integrity without panic-replacing the pump. That’s a calm decision backed by a design meant to be serviced—rare in modern equipment.
Modular Parts, Real Savings
A threaded assembly lets you address specific failures. That’s good engineering and good stewardship of your investment. Fewer full pulls, less downtime.
On-Site Repairs
With proper rigging and safety, many issues can be fixed without sending equipment back to a factory. PSAM stocks common wear parts for Myers—ask before you plan a whole-day pull.
Diagnostic Clarity
When parts come apart cleanly, you learn what failed and why. That informs upgrades: pipe size, torque arrestors, arresting water hammer, or tank sizing.

If you value ownership cost as much as uptime, serviceability is a must-have feature—Myers checks that box.
#8. Installation Components That Make or Break Performance - Pressure Tank, Pitless Adapter, Check Valve, and Proper Drop Pipe
A premium pump can’t overcome a sloppy install. The surrounding system determines whether your Myers well pump lives long or dies young.

Start with a correctly sized pressure tank. Aim for at least 1 minute of runtime per cycle; 1–2 minutes is better. Use a quality pressure switch—40/60 or 50/70 depending on your needs—and mount it on a proper tank tee with a gauge and relief valve. In the well, a brass or stainless pitless adapter ensures a sealed, freeze-proof lateral connection. Use drop pipe sized for flow: 1-1/4" for most 10–12 GPM installs reduces friction and noise. Add a torque arrestor, cable guards, and a secure well cap. Every splice gets a heat-shrink wire splice kit rated for submersible duty.

We updated the Castrillo system with a larger tank, new pitless, and correct pipe. The difference? Whisper-quiet starts, stable pressure, and a motor that doesn’t fight voltage sag or hydraulic shock.
Don’t Skimp on the Tank
Short cycling is pump murder. Proper tank sizing and pressure settings extend motor life and stabilize household pressure.
Sealed, Frost-Proof Wellhead
A quality pitless adapter and sealed cap keep contamination and freeze at bay. Rural winters demand it; so does your water quality.
Pipe and Fittings Matter
Undersized pipe erases efficiency. We stock full fittings kits and tank tees at PSAM—use the right parts once.

The pump is the heart; the system is the circulatory network. Build both right, or you’ll chase problems that aren’t the pump’s fault.
#9. Detailed Comparison: Myers vs Goulds and Red Lion in Real-World Rigs
Material and staging decide how a pump ages. Myers leans on 300 series stainless components and Teflon-impregnated staging to deliver high efficiency under load. Goulds has relied on assemblies with cast iron elements in certain models—durable when new, but vulnerable to corrosion in acidic or mineral-heavy wells. Red Lion’s use of thermoplastic housings keeps initial price low, yet those housings flex under repeated pressure cycles and can crack with thermal expansion or water hammer. Meanwhile, Myers couples stainless flow paths with a Pentek XE motor, keeping internal temperatures down and thrust bearings happy.

In the field, this plays out predictably. Myers runs cooler, holds curve position longer, and resists grit scarring. Goulds units in low-pH or high-iron water show pitting and rising amp draw over time. Red Lion installs face housing deformation and early stage wear, especially when tanks are undersized or irrigation loads push duty cycles. Over 8–15 years, Myers maintains usable GPM without creeping energy bills and nuisance shutoffs. Add the 3-year warranty, and the ownership math tilts further: fewer replacements, fewer service calls, lower kWh. For rural families dependent on wells, that’s reliability you can budget around—worth every single penny.
#10. Best Deep Well Submersible Pick - Myers 1–1.5 HP Multi-Stage for 250–380 Foot TDH Residential Systems
Deep wells punish margins. Pick a deep well pump with staging and motor headroom, or you’ll fight pressure loss every summer. Myers Predator Plus in 1 HP to 1.5 HP configurations handles 250–380 feet TDH at 10–12+ GPM comfortably.

On installations where static levels dip seasonally, a pump with stout staging keeps showers strong at 6 pm when irrigation is rolling. The Pentek XE motor handles extended run cycles without cooking. At 230V single-phase, amperage draw remains predictable, protecting breakers and pressure controls. If you need 12–15 GPM for irrigation zones, stepping to 1.5 HP with more stages maintains headroom.

While the Castrillos sit around 280–300 feet TDH in operation, I’ve put the 1.5 HP Predator Plus into 340–360 feet TDH homes with sprinkler manifolds. Pressure holds, and sprinklers finally throw end-to-end patterns.
Sizing for Seasonal Drawdown
If your water table drops 20–40 feet in August, you need a pump that can deliver head at both spring and summer setpoints. Myers’ multi-stage design thrives here.
Set Your Pressure Window
Decide on 40/60 vs 50/70. Higher pressure improves fixtures but increases head demand. Myers curves let us place your operating point precisely.
Discharge and Piping
A 1-1/4" NPT discharge upstream of the tank keeps friction low. Restrictive piping wastes horsepower and heats the motor.

Choose a deep-well pump that gives you headroom. Myers does—without asking for special controls or complex add-ons.
#11. Myers Jet Pump Clarity - When Shallow or Convertible Jet Beats a Submersible
Not every well needs a submersible. For shallow wells (25–50 ft) or where drop pipe installation is impractical, a Myers jet pump—shallow or convertible jet pump—can be the right call.

Jet pumps sit above grade, making service simple. For wells under 25 feet to water, a shallow jet is efficient and easy to winterize. For 25–80 feet, a convertible jet with the correct ejector kit can draw reliably. While submersibles remain my go-to for noise and efficiency, jet pumps shine in specific cases: cabin systems that need seasonal drain-down, crawlspaces where piping access is easy, or older wells with obstructions.

For the Castrillos’ 220-foot set, a jet wasn’t appropriate. But their neighbor’s 40-foot sand point well? A Myers shallow jet paired with a frost-proof installation works beautifully year-round.
Shallow and Convertible Basics
Shallow jets use a single suction line and are great under 25 feet. Convertible jet pumps use a two-pipe ejector setup for deeper applications up to ~80 feet.
Service and Winterization
Above-grade mounting means easy access. Draining for winter is trivial compared to pulling a submersible.
Noise and Efficiency
Jets are louder and less efficient than subs. If you value simple service over sound and kWh, jets hold their own.

When the well and use case fits, a Myers jet pump is the smarter, simpler tool.
#12. Electrical and Protection Essentials - Voltage, Wire Gauge, Surge, and Pressure Controls
Good pumps die for bad electrical reasons. Match voltage, size the wire gauge, and install surge suppression.

Most Myers submersibles run 230V single-phase. Verify service voltage and calculate drop based on distance to the wellhead. Undersized wire leads to low voltage at the motor, higher amp draw, heat, and nuisance thermal trips. For surge protection, a panel-mounted SPD plus bonding at the well cap limits lightning damage. Your pressure switch should match your pressure tank precharge (2 PSI below cut-in). Poor settings cause short cycling, pressure swings, and motor stress.

The Castrillos’ breaker panel, wire size, and run length were borderline for a 3/4 HP. With the 1 HP upgrade, we upsized the conductor per PSAM’s chart. Result: clean starts, stable amps, no hot splices.
Wire and Voltage Discipline
Always check the run length and current. PSAM has wire sizing tables for amperage draw at 230V—use them.
Pressure Switch and Tank
A sloppy switch setting creates chaos. 40/60 with 38 PSI tank precharge is a common baseline. Verify with a reliable gauge.
Surge Protection
Lightning happens. Protect the motor and controls with an SPD and proper grounding.

Electrical discipline turns a good pump into a great system. Skip it, and even the best pump suffers.
#13. Detailed Comparison: Myers vs Franklin Electric on Serviceability, Control Simplicity, and Ownership Cost
Control philosophy and service access separate brands. Myers Predator Plus favors field serviceable threaded assemblies and supports both 2-wire and 3-wire configurations without locking you into proprietary control boxes. Franklin Electric submersibles often integrate with specific boxes and dealer networks. On materials, Myers leans heavily into 300 series stainless, while Franklin offers mixed-material lines. Motor-wise, Myers uses the Pentek XE high-thrust platform with thermal and lightning protection and strong efficiency, holding the operating point near BEP longer as parts wear.

In practice, I see Myers installations needing fewer specialized parts calls. A simple 2-wire Predator Plus avoids an external control box where appropriate—fewer components to corrode or fail in damp basements. When a check or stage needs attention, the threaded design allows on-site fixes by any qualified contractor, not just a brand-locked dealer. Over a decade, owners spend less on callouts and replacements. Add Myers’ 3-year warranty versus shorter norms in the market, and the total cost of ownership consistently favors Myers. For rural homeowners who cannot afford downtime and prefer straightforward service, Myers’ design choices save time, stress, and money—worth every single penny.
#14. Applications Beyond the Kitchen Sink - Irrigation, Livestock, and Off-Grid Backup
A pump that handles showers might stumble on sprinklers or livestock demands. Myers’ lineup—from Predator Plus Series subs to booster pumps—covers those loads.

Irrigation needs higher sustained flow; choose a pump with duty cycle headroom and size zones to stay within the pump’s curve. Livestock systems benefit from larger storage and float-controlled troughs to minimize cycling. For off-grid or backup readiness, a generator with proper surge capacity and clean 230V output keeps the AC electric pump happy. If you’re integrating a booster pump for rainwater cisterns or low-pressure municipal backup, Myers offers efficient centrifugal options paired with solid switches and protection.

The Castrillos added a small booster for their garden cistern, leaving the well pump to handle the house. Splitting loads extends life and simplifies troubleshooting.
Irrigation Strategy
Balance zones to 60–80% of the pump’s BEP flow. Avoid deadheading. Use pressure-regulated heads for consistency.
Livestock Reliability
Large storage smooths demand peaks. Protect against freezing and keep valves clean to prevent water hammer.
Backup Planning
Size your generator for motor surge (3–5× running amps). Test annually, not when you need it.

Your Myers pump supports more than domestic water if you plan the system well.
#15. Installation Best Practices and Rick’s Must-Haves - From Torque Arrestors to Proper Splices
Smart installs look boring—and that’s the point. My checklist has saved hundreds of pumps:
Use a torque arrestor and cable guards. Prevent cable rub and shock load on starts. Heat-shrink wire splice kits only—no electrical tape “fixes.” Stainless check valve above the pump if required by code/system design; verify internal check performance. Secure safety rope for manageable pulls. Label length and set depth. Sanitize on completion. Chlorinate and flush; then test water. Document serials, set depth, wire size, and pressure settings for future service. Set tank precharge correctly—2 PSI under cut-in; confirm with an accurate tire gauge.
For the Castrillos, these basics turned a headache into a system that just works. Strong showers, quiet operation, and a pump that runs cool.
Seal the Wellhead
A tight well cap and clean conduit entries protect water quality. Small details, big impact.
Pipe and Fittings Discipline
Use unions and a tank tee with a proper drain port. Make future maintenance simple and safe.
Start-Up Checklist
Purge air, verify amperage against nameplate, and confirm cut-in/cut-out transitions are smooth.

Follow the fundamentals, and your psam myers pump will pay you back every single day.
FAQ: Expert Answers to Your Most Pressing Questions 1) How do I determine the correct horsepower for my well depth and household water demand?
Start with TDH and flow. TDH equals static water level + drawdown + friction losses + desired pressure (PSI × 2.31). Most homes need 8–12 GPM. Cross that operating point on the Myers pump curve and choose the model where it lands near the BEP. As a rule of thumb: 1/2 HP handles ~150–180 ft TDH at 7–10 GPM, 3/4 HP handles ~200–240 ft at 8–10 GPM, and 1 HP covers ~250–300 ft at 10–12 GPM. For deeper systems or irrigation, step to 1.5–2 HP with more stages. Example: A 220-foot well needing 60 PSI (138 ft) and 12 GPM may total 280–300 ft TDH. A Myers 1 HP Predator Plus at 230V fits beautifully. Recommendation: call PSAM with your well report, pipe lengths, and fixture count. We’ll run the numbers so your Myers well pump hits the curve sweet spot on day one.
2) What GPM flow rate does a typical household need and how do multi-stage impellers affect pressure?
A typical three-bath home runs well at 8–12 GPM. If you irrigate or run livestock troughs, you may need 12–15 GPM in specific windows. Multi-stage designs stack impellers to build head; more stages equal higher pressure at a given flow. That means a multi-stage pump can meet 50–70 PSI household demands even at depth. On a curve, as GPM rises, head falls. You want your most common demand (say 10 GPM) to match your desired PSI at your TDH. Myers’ engineered composite impellers keep their edge, preserving head and avoiding the “weak shower” that shows up as impellers wear. For families like the Castrillos, a properly staged 1 HP unit holds 10–12 GPM at 60 PSI without drifting off the curve in summer.
3) How does the Myers Predator Plus Series achieve 80% hydraulic efficiency compared to competitors?
Efficiency starts with materials and geometry. Myers uses engineered composite impellers with tight diffuser clearances, maintained by stainless wear rings and 300 series stainless steel housings that resist distortion. Run at or near BEP, hydraulic slip is minimized, so more motor watts turn into water work. Pair this with the Pentek XE motor—high-thrust bearings, optimized windings, and thermal overload protection—and you avoid heat losses that sap performance. In my field measurements, Predator Plus units consistently draw stable amperage at 230V and hold pressure under long duty cycles. Over a year, that translates to up to 20% energy savings versus less efficient stacks, especially when the competitor’s materials wear and efficiency degrades.
4) Why is 300 series stainless steel superior to cast iron for submersible well pumps?
Submersibles live in chemistry you can’t see. 300 series stainless steel resists corrosion from low pH, high chloride, and iron-laden water far better than cast iron. Stainless maintains dimensional stability, so impeller-diffuser clearances stay tight, preserving head and GPM rating. Cast iron pits and rusts, which increases turbulence, reduces efficiency, and sheds debris into the flow path. Stainless also handles thermal expansion and pressure cycles without cracking. In wells like the Castrillos’—where water chemistry fluctuates seasonally—stainless construction is the difference between replacing at five years and seeing 10–15 years of service.
5) How do Teflon-impregnated self-lubricating impellers resist sand and grit damage?
Sand scores surfaces and rounds impeller edges, weakening pressure. Myers uses Teflon-impregnated staging that is self-lubricating, reducing friction when micro-contact occurs due to particulates. The material’s lubricity and wear resistance keep the impeller’s geometry intact longer, maintaining head and reducing amperage draw. In practical terms, a grit-exposed pump without these materials sees early efficiency loss and overheating. With Myers, abrasive wear slows dramatically. For the Castrillos, moving from a plain thermoplastic stack to the Myers composite eliminated the seasonal pressure sag they’d accepted as “normal.”
6) What makes the Pentek XE high-thrust motor more efficient than standard well pump motors?
The Pentek XE motor combines high-thrust bearings, optimized stator windings, and precise rotor balancing to reduce losses and manage axial load from stacked impellers. Lower slip and better heat management translate to higher motor efficiency and cooler operation. Add thermal overload and lightning protection, and you get a motor that stays online through voltage dips and summer storms. Efficiency is not only a spec—it’s seen in steady pressure at 50–70 PSI and fewer nuisance trips. In installs I service, Pentek XE motors maintain nameplate amperage for years, which tells the story better than any brochure.
7) Can I install a Myers submersible pump myself or do I need a licensed contractor?
If you’re comfortable with electrical work, rigging, and plumbing, a careful DIY install is possible. Many homeowners successfully install 2-wire well pumps with PSAM’s guidance. That said, a licensed contractor brings pulling rigs, safety protocols, and experience with pitless adapters, drop pipe, and proper wire splice kits. Missteps—like undersized wire, wrong pressure switch settings, or poor splicing—can shorten pump life drastically. My recommendation: DIYers handle accessible replacements under 150 feet and straightforward systems, while deep wells, 3-wire configurations, or complex manifolds belong to pros. Either way, PSAM provides diagrams, checklists, and phone support to set you up for success.
8) What’s the difference between 2-wire and 3-wire well pump configurations?
A 2-wire configuration houses start components inside the motor. You run power and ground—no external control box—which simplifies installation and reduces failure points. It’s ideal for 1/2–1 HP residential systems with moderate TDH. A 3-wire configuration uses an external control box containing start capacitors and relays, offering easy service access and better diagnostics for higher HP applications. Both are supported by Myers. Choosing between them depends on HP, depth, and service philosophy. For the Castrillos’ 1 HP at ~300 ft TDH operational point, 2-wire worked perfectly—clean installation, fewer parts, reliable starts.
9) How long should I expect a Myers Predator Plus pump to last with proper maintenance?
With correct sizing, proper electrical, and sound hydraulics, 8–15 years is a realistic expectation. I’ve seen 20–30 year runs with pristine water chemistry and meticulous system care. Key factors: run the pump near BEP, ensure adequate pressure tank sizing to limit starts per hour, and protect against surges. Inspect pressure settings annually, check for leaks that cause short cycling, and test amperage against nameplate under load. The Myers 3-year warranty covers the early life window; beyond that, good installs pay dividends. The Castrillos are set up for a long run: correct TDH match, upsized wire, larger tank, and surge protection.
10) What maintenance tasks extend well pump lifespan and how often should they be performed?
Annually: verify pressure switch cut-in/cut-out, set tank precharge 2 PSI below cut-in, and check for rapid cycling. Inspect wiring and grounds, and test running amps compared to the motor nameplate. Every 2–3 years: inspect the well cap seal, check pitless integrity, and evaluate water for sand or iron changes. After storms or outages: test surge protection and confirm the pump starts cleanly. If you irrigate heavily, review zone sizing to avoid deadheads. When you marry a Myers submersible well pump to a well-maintained system, you’re stacking the deck in favor of longevity.
11) How does Myers’ 3-year warranty compare to competitors and what does it cover?
Myers’ 3-year warranty exceeds common 12–18 month coverage in the market. It covers manufacturing defects and performance failures under normal use. When combined with PSAM’s documentation and support, claims move efficiently. Competitors with shorter terms shift more risk to the customer—especially painful in rural areas where service calls are costly. Pair the warranty with proven materials—300 series stainless, Teflon-impregnated staging, Pentek XE motor—and you’re not just buying a warranty, you’re buying a pump with fewer reasons to need one.
12) What’s the total cost of ownership over 10 years: Myers vs budget pump brands?
Budget pumps tempt with low upfront cost but often deliver 3–5 year lifespans. Add two replacements over a decade, two pull/install trips, rising kWh from worn impellers, and emergency downtime—and the “cheap” choice becomes expensive. Myers’ Predator Plus typically runs 8–15 years, maintains 80%+ hydraulic efficiency near the curve, and carries a 3-year safety net. Factor in lower energy use (up to 20% annually at BEP), fewer service calls, and less chance of a Friday-night failure, and the math turns. In my customers’ books—and in the Castrillos’ experience—Myers wins the 10-year cost race by a wide margin.
