PSAM Myers Pump for Agricultural Irrigation: A Buyer’s Guide
The pressure gauge danced, then fell flat to zero. Sprinkler lines coughed air. Drip zones starved. When you’re trying to keep crops alive, a dead pump isn’t an inconvenience—it’s an emergency. Most ranch and farm calls I get start the same way: “We’ve got no water.” In irrigation season, that’s the difference between a healthy harvest and a costly write-off.
Meet the Olanders. Lucas Olander (38), a specialty-vegetable grower, and his spouse, Mireya (36), a school nurse, work 40 acres outside Ord, Nebraska. Their 265-foot well had been running a 1 HP thermoplastic pump that couldn’t handle pressure cycling. After two seasons and a mid-July heat wave, the housing cracked and their field went bone dry for three critical days. Their peak irrigation demand hits 18 GPM across rotation zones, with 52–58 PSI at the header. What Lucas needed wasn’t another “good deal.” He needed a proven, properly sized solution.
That’s why this guide zeroes in on the real decisions that keep ag operations running. We’ll cover why a Myers Pumps Predator Plus Series submersible well pump outlasts budget options, how to size by GPM rating and TDH (total dynamic head) using the pump curve, whether a 2-wire well pump or 3-wire well pump fits your install, what 300 series stainless steel buys you in harsh water, and why the Pentek XE motor saves on power every single month. We’ll dig into field-serviceable designs, best practices for irrigation manifolds and pressure controls, electrical protections, warranty impacts on total cost of ownership, and how PSAM gets product on your truck fast.

#1. Predator Plus Series Durability – 300 Series Stainless Steel and Field-Serviceable Threaded Assembly for Harsh Agricultural Duty
When irrigation runs sunrise to sunset, materials matter; pumps that cheat on metallurgy lose to grit, minerals, and pressure cycling long before harvest.
Myers engineered the Predator Plus Series around 300 series stainless steel—shell, discharge bowl, shaft, coupling, wear ring, and suction screen. That metallurgy resists chloride attack, acidic pH, and abrasion that would shred softer alloys or thermoplastic parts. The assembly is fully threaded, not potted or swaged, so trained installers can open the stack, replace worn stages, and reassemble in the field—no waiting for factory-only repairs. Pair this body with a matched submersible well pump motor and you get clean, stiff hydraulics across the curve with minimal loss to wear. The result is reliable pressure to your irrigation manifold, even as water levels fluctuate or zones rotate on timers.
Against Red Lion’s thermoplastic housings, I’ve seen repeated cracking at pressure changes and temperature swings. On the Olander farm, that crack ended three days of irrigation in July—an expensive lesson. We replaced their failed unit with a Myers Pumps stainless Predator Plus, staged to their 265-foot well and zone demand. Lucas and Mireya now run dependable cycles at dawn and dusk without babying the system.
Stage Count and Wear Margins
Multi-stage stacks concentrate head generation per wheel. Stainless tie rods and diffusers in the Predator Plus resist creep and stage deformation under heat. That stability keeps impeller-to-diffuser clearances consistent, protecting pressure delivery as the season wears on. Aim for a model that runs near its best efficiency point at your average zone demand.
Corrosion Resistance in Mineral-Rich Aquifers
When water carries iron, sulfur, or high TDS, 300 stainless pays back fast. It limits pitting and prevents flake-off that can jam impellers. If your water lab shows aggressive chemistry, skip mixed materials and buy stainless end-to-end.
Field Service Wins
Threaded construction means you can swap out a worn stage kit or suction screen on-site. Downtime drops from days to hours. For irrigation customers on a schedule, that’s real money saved in lost yield and labor.
Key takeaway: Stainless plus serviceability beats thermoplastic every time—choose the Predator Plus and keep water moving.
#2. Pentek XE High-Thrust Motor – Energy Efficiency, Thermal Protection, and Strong Starts for Long Irrigation Days
Energy bills and restarts add up fast during irrigation season; pick the motor that sips power and shrugs off heat.
The Predator Plus pairs to the Pentek XE motor, a rugged, high-thrust, single-phase design purpose-built for frequent cycling and long-duty irrigation runs. Thermal sensors and robust winding insulation shed heat safely under hard pulls, while high-thrust bearings stabilize the shaft under multi-stage loads. The motor’s efficiency shows up on your power bill: when you operate near BEP on the pump curve, Myers systems routinely post 80%+ hydraulic efficiency, cutting energy costs 15–20% annually against typical farm setups. Lightning protection and moisture barriers reduce the “random-failure” gremlins that strike mid-season.
Lucas and Mireya needed a motor that could spin up cleanly at 230V against a long lateral line and keep steady during zone handoffs. A 1.5 HP Predator Plus with Pentek XE did exactly that—no sag, no stall, just consistent pressure across their drip zones and micro-sprays.
High-Thrust Bearings Under Staging Loads
Stacked impellers generate axial thrust that punishes ordinary bearings. Pentek XE uses oversized, irrigation-grade thrust assemblies that prevent endplay and shaft rub, extending life and preserving flow.
Thermal and Surge Protections
Built-in thermal overload protection reduces burnout risk during hot days or partially closed irrigation valves. Enhanced surge resilience means a nearby storm is less likely to end your week.
Efficiency = Lower Cost Per Gallon
At 12–18 GPM operating points with the right staging, XE motors consistently convert watts into water, not waste heat. Over a season, those kilowatt-hours matter, especially on farms running pumps six to ten hours a day.
Key takeaway: The right motor is your quiet partner—Pentek XE turns electrical energy into reliable, cool-running water, day after day.
#3. Sizing by Curve, Not Guesswork – Match GPM Rating and TDH to Your Zones, Headers, and Well Depth
Undersize a pump and zones starve; oversize it and you buy cavitation, wasted energy, and early failures.
Proper selection starts with two numbers: your target GPM rating by zone and your TDH (total dynamic head). TDH sums static lift (pumping level up to grade), pressure requirements at the header (PSI x 2.31), and friction losses in your drop pipe and laterals. With those, you land on a point on the pump curve. Pick the Predator Plus model whose BEP envelopes that point. For farms like the Olanders—265-foot well, 52–58 PSI header, 14–18 GPM demand per active zone—a 1.5 HP, 11–13 stage Predator Plus nails the duty point with reserve head for seasonal drawdown.
Calculate TDH Accurately
Static lift: pumping level, not just well depth. If water stands at 175 feet in July, use that. Desired PSI: Convert 55 PSI to ~127 feet of head (55 x 2.31). Friction: Use pipe size and length—1-1/4" riser versus 1" makes a difference at 16 GPM.
Stage Count to Cover Drawdown
Staging isn’t only about depth; it’s about head at flow. Add reasonable margin (10–15%) for seasonal drawdown and filter loading. Don’t overdo it; too much head pushes you off the efficient part of the curve.
Zone-by-Zone Planning
Group emitters so each zone runs in the pump’s sweet spot. If a field sometimes wants 10 GPM and other times 18 GPM, consider throttling strategy, VFD booster downstream, or splitting zones more evenly.
Key takeaway: Get your point on the curve right once; enjoy years of efficient, stable irrigation.
#4. 2-Wire vs 3-Wire – Simpler Installs, Fewer Boxes, and Clear Control with Myers Predator Plus
Wiring choices impact upfront cost, troubleshooting, and future serviceability.
A 2-wire well pump integrates start components inside the motor—clean install, fewer parts to fail topside, and often the lower total price. A 3-wire well pump uses an external control box for start capacitors and relays, making above-ground troubleshooting easier and allowing for certain advanced controls. Myers Predator Plus offers both, which lets you tailor to your site, installer preference, and budget. For many irrigation systems, a 2-wire at 230V with solid overcurrent protection and quality splices is the fast, reliable path; on complex multi-zone farms with remote diagnostics, a 3-wire might earn its keep.
Lucas and Mireya chose a 2-wire build to avoid an extra box on their pump house wall and shave a few hundred dollars off install costs. Their priority was quick restoration and long, low-maintenance runs.
When 2-Wire Shines
Fewer components = fewer failure points. Cleaner install in tight pump houses. Lower material cost—no separate control box to purchase and mount.
When 3-Wire Wins
Easier to diagnose start issues at the surface. Some advanced controls integrate better with external capacitors. Preferred by certain contractors for complex telemetry setups.
Protection First, Either Way
Use proper gauge wire, waterproof heat-shrink splices, and quality overload protection in your panel. Poor splices cause more midseason failures than motors do.
Key takeaway: Myers gives you choices without handcuffs—pick the wiring strategy that fits your operation and budget.
Detailed Comparison: Myers vs Franklin and Red Lion (Why Stainless, Serviceable, and Simple Wiring Win)
On materials and motors, the differences are stark. Myers’ Predator Plus relies on full-stack 300 series stainless steel and a matched Pentek XE motor engineered for 80%+ efficiency near BEP. By contrast, many Red Lion irrigation installs I encounter use thermoplastic housings that fatigue under thermal expansion and pressure cycling. For control architecture, Franklin Electric builds solid motors, but their ecosystems often lean toward dealer-driven, proprietary control boxes, adding layers that small farms may not need. Efficiency, meanwhile, is a function of curve matching and hydraulic design; Myers impellers hold clearances longer in sandy, mineral-rich wells, preserving performance season after season.
In the field, that translates to downtime and dollars. A Red Lion crack doesn’t just leak—it ends irrigation until you pull and replace. A proprietary control path can slow emergency fixes if you’re outside a dealer network. With the Predator Plus, I can pull a unit, swap stages if needed, and button up the job quickly. More uptime, simpler service, and less energy burned per gallon moved.
When you rely on wells for crops, reliability is profit. Between stainless construction, serviceable design, Pentair-backed motors, and PSAM stock on the shelf, a Myers Predator Plus setup is worth every single penny.
#5. Multi-Stage Muscle for Depth – Deep Well Pump Performance to 490 Feet of Head Without Breaking the Bank
Agricultural wells aren’t always shallow, and zone pressures don’t care how deep your water sits.
As a deep well pump, the Predator Plus line spans shut-off heads from roughly 250 to 490 feet depending on model and staging. More stages mean more head per revolution; the trick is pairing stage count with the right operating GPM so you hold BEP efficiency and avoid running too far right or left on the Meyer water pump types pump curve. At 200–300 feet of TDH and 12–20 GPM, Myers offers 1–2 HP options that balance thrust, amperage draw at 230V, and motor cooling velocity. Stainless components keep those clearances true, which preserves head production under summer loads.
The Olanders push mid-50s PSI at their header—call it ~127 feet—plus static lift and friction. Their 1.5 HP, mid-teens-stage Predator Plus keeps zones alive even when the water level drops in August.
Finding the Sweet Spot at BEP
Aim for your duty point to sit in the center third of the curve. That’s where vibration is lowest, amperage is smooth, and heat is minimal. Pumps sized this way live longer.
Motor Cooling and Flow
Submersible motors cool in flow. If you run low GPM through a large annulus, consider a flow sleeve to maintain adequate velocity past the motor can. Myers’ guidance makes this straightforward.
Reserve Head Matters
Irrigation systems evolve—filters load, emitters change, seasonality bites. A modest head reserve (not oversized) keeps you off the ragged edge.
Key takeaway: Stage it right once—your pump will reward you with years of stable pressure.
#6. The Warranty and Service Equation – Myers’ 3-Year Coverage and Field-Repairable Design vs Dealer-Only Paths
Warranty isn’t just paperwork—it’s risk allocation for your farm.
Myers stands behind Predator Plus with a full 36-month, industry-leading warranty. In my shop, that’s not marketing fluff; it’s leverage when something goes wrong. The pump’s field-serviceable construction lets qualified contractors replace wear components on-site, often avoiding complete replacement. That’s real uptime. With PSAM’s stocking strategy, we ship same day on in-stock pumps, so a bad week doesn’t turn into a lost month.
Lucas told me the warranty was the final nudge. After losing an entire weekend to source a prior-brand replacement, he wanted a partner, not a bet.
Documentation and Compliance
Follow installation best practices—proper wire gauge, torque arrestor, sanitary well cap, and approved splices. Keep your paperwork. Good installs keep warranties clean and claims smooth.
Service Access and Parts
Myers publishes parts breakdowns, curves, and repair procedures. You’re not guessing, you’re following a roadmap. That transparency shortens service windows.
Downtime Math
Three days without water in July can cost more than a pump upgrade. Add in labor, filters fouled by stop-start events, and plant stress—and the math points to premium gear.
Key takeaway: Warranty plus serviceability equals predictable seasons—exactly what an irrigation operation needs.
Detailed Comparison: Myers vs Goulds and Franklin (Controls, Corrosion, and Ownership Cost)
Let’s stack common ag choices. With Goulds Pumps, I often see cast-iron components in the hydraulic end. In acidic or mineral-heavy Nebraska wells, that iron loses to chemistry—pitting, scale, and in worst cases, flaking that scars impellers. Myers Pumps counters with full 300 series stainless steel, so the wet end stays clean and tight longer. On controls, Franklin Electric motors are widely used but frequently tied to proprietary or dealer-centric control ecosystems, which can slow field fixes. Myers’ Predator Plus keeps options open—run 2-wire well pump for simple installs or 3-wire well pump for serviceable topside controls.
In daily operation, corrosion creep shows up as pressure loss by late season; your 16 GPM becomes 12, and filters clog faster. Dealer-only control paths also mean you’re waiting on a specific box if it fails—bad news during a heat spike. With Myers, I can spec stainless through-and-through, use a flexible control approach, and keep repairs in the hands of any qualified contractor.
Over a decade, fewer failures, fewer specialized parts, and steadier efficiency mean your cost per gallon is lower. For farms balancing risk and cash flow, Myers is worth every single penny.
#7. Installation for Irrigation Reality – Pressure Targets, Manifolds, and Electricals that Protect Your Investment
Good pumps die early in bad systems; build the environment your pump deserves.
Start with clean hydraulics: size the riser and header to keep velocity sane (under ~5 ft/s), use long-radius fittings on your manifold, and set filters after the header with isolation valves for quick service. Keep pressure at the header stable with appropriately set pressure switches or irrigation controllers; slam opens/closures kill stages faster than any warranty can help. Electrical side: 230V supply, correct breaker size per amperage draw, and surge protection at the panel. Finally, use quality pitless components, a sanitary seal, and a secured drop pipe with torque arrestor and safety rope.
For the Olanders, a reworked header and upgraded electrical protection paired with the new pump ended their pressure swings and mid-day nuisance trips.
Pressure and Control Strategy
If you run both domestic and irrigation off one well, consider a dedicated irrigation controller that stages zones without hammer. Keep your setpoint steady—55 PSI at header is common for mixed drip/micro-sprays.
Filtration and Air Management
Install spin-down or disk filters as needed; plumb in air reliefs at high points. Air pockets fake out gauges and create erratic flow.
Electrical: Do It Right Once
Use THHN/THWN conductors in conduit to the wellhead, waterproof heat-shrink splices, and surge protection. Many “mystery failures” trace back to poor splices and lightning.
Key takeaway: Great installs make good pumps legendary. It’s that simple.
#8. PSAM Support and Speed – In-Stock Myers Pumps, Curves, and Kits That Get You Water Fast

Key takeaway: With PSAM stocking and support, “need water now” becomes “water is on.”
FAQ: Myers Predator Plus for Ag Irrigation
How do I determine the correct horsepower for my well depth and household water demand?
Start by nailing your flow and head. List your maximum simultaneous irrigation zone demand (say 16–18 GPM) and convert your pressure target to head (55 PSI ≈ 127 feet). Add static lift from pumping level—if water sits at 175 feet during July drawdown, include that. Finally, add friction loss for your riser and laterals. That sum is your TDH (total dynamic head). Place your operating point (GPM vs head) on the pump curve. Pick a Myers Pumps Predator Plus model whose BEP covers that point. For 12–18 GPM at 230–300 feet TDH, I often land on 1–1.5 HP. If domestic supply shares the well, size to the higher irrigation requirement and use controls to protect the system. Rick’s recommendation: choose the smallest HP that keeps your duty point at or just left of BEP; that buys efficiency, cool running, and long life.
What GPM flow rate does a typical household need and how do multi-stage impellers affect pressure?
Most homes function well at 8–12 GPM; irrigation bumps that upward quickly. Drip and micro-sprays often run 10–20 GPM per active zone. Multi-stage submersibles generate head by stacking impellers; each stage adds pressure, so more stages equal higher head at a given flow. The Predator Plus Series offers multiple staging options so you can hit 50–60 PSI at the header while lifting from 150–300+ feet. Stay near the pump’s BEP—excessive flow at low head invites cavitation and heat; too little flow at high head can push amperage up and cool the motor poorly. Match your zone design to the selected curve for best performance.
How does the Myers Predator Plus Series achieve 80% hydraulic efficiency compared to competitors?
Efficient hydraulics come from tight, durable clearances and well-profiled impellers. With 300 series stainless steel housings maintaining geometry and the matched Pentek XE motor holding RPM under load, Predator Plus units run close to design points season after season. In practice, that means more water per watt, especially when your operating point sits in the middle third of the pump curve. Against budget brands with thermoplastic stacks that deform, efficiency drifts—pressure sags, and energy use rises. Myers keeps stage alignment and wear minimal, so you keep seeing the pressure and flow you paid for.
Why is 300 series stainless steel superior to cast iron for submersible well pumps?
Submerged cast iron faces pitting and scale in aggressive water, especially with low pH or high chlorides. Over time, those pits grow, flake, and erode impeller edges, bleeding efficiency. 300 series stainless steel resists corrosion and abrasion far better, preserving the exact clearances that make a multi-stage pump perform. It also tolerates temperature cycling without the stress cracking I see in mixed-metal stacks. In agricultural wells with grit or iron, stainless stays smooth, which protects impellers, reduces vibration, and extends seal and bearing life. Bottom line: stainless maintains factory performance longer—critical for irrigation season reliability.
How do Teflon-impregnated self-lubricating impellers resist sand and grit damage?
While not every Predator Plus model uses Teflon-loaded composites, Myers’ engineered stage materials are designed to glide through minor particulate without galling. Self-lubricating surfaces reduce friction heat and resist abrasion much better than unfilled plastics. In sandy wells, that matters: impellers keep their edges, diffusers hold shape, and efficiency doesn’t nosedive by August. Pair this with a good intake screen and reasonable zone filtration, and you’ll see multi-year stability in pressure. In my experience, the combination of durable stage materials and stainless housings lets Myers stacks outlast lower-cost competitors by a wide margin.
What makes the Pentek XE high-thrust motor more efficient than standard well pump motors?
The Pentek XE motor integrates high-quality windings, optimized rotor/stator geometry, and oversized thrust bearings that limit friction under multi-stage loads. Lower internal losses translate into cooler operation and more power to the impellers. Smart thermal overload protection prevents heat damage during heavy cycles, and surge robustness reduces the odds that a squall line ends your week. At typical farm operating points—12–18 GPM at 230V—XE motors hold amperage steady and deliver consistent RPM, which preserves the exact relationship between stages and performance. Efficiency here is not hype; it shows up in kilowatt-hours saved and in longer motor life.
Can I install a Myers submersible pump myself or do I need a licensed contractor?
Capable DIYers can install a submersible well pump, but agricultural systems add complexity—correct wire sizing over long runs, sanitary practices at the well, safe rigging to set the pump, and proper manifold design. A licensed contractor brings rigging gear, torque arrestors, sanitary seals, crimp/heat-shrink splices, and testing meters. Improper splices, under-gauged wire, or poor venting cause many early failures I’m called to fix. If you DIY, consult PSAM for a parts checklist and curve selection, and follow code. My recommendation for irrigation installs: hire a pro for the set, then handle manifold tweaks and controller programming in-house.
What’s the difference between 2-wire and 3-wire well pump configurations?
A 2-wire well pump houses the start components inside the motor—cleaner installation and one less box to mount. A 3-wire well pump uses an external control box for the start capacitor and relay, which can simplify above-ground troubleshooting and certain integrations. Performance at the water end is similar when sized correctly. For many farms, 2-wire at 230V offers a lower upfront cost and fewer failure points; complex telemetry or remote diagnostics might tilt you toward 3-wire. Myers offers both in the Predator Plus lineup, so you can match your preference and control philosophy without compromising pump quality.
How long should I expect a Myers Predator Plus pump to last with proper maintenance?
With correct sizing and good installation, expect 8–15 years. I’ve seen well-kept systems reach 20–30 years, especially where water chemistry is friendly and filtration is maintained. Key factors: operate near BEP on the curve, protect against dry-run, keep filters serviced so the pump isn’t fighting plugged screens, and maintain smooth zone transitions to avoid water hammer. The 3-year warranty covers manufacturing issues, but your maintenance habits—pressure checks, electrical inspections, and seasonal drawdown monitoring—determine whether you hit that upper range.
What maintenance tasks extend well pump lifespan and how often should they be performed?
Quarterly: Check header pressure with zones on; compare to baseline to catch drift. Flush filters. Inspect for air in lines. Seasonally: Pull and inspect filter elements, test pressure switch cut-in/cut-out, verify controller timing to prevent zone overlap hammer. Annually: Electrical check—breaker, lugs, grounds; inspect splices at the well cap; test surge protection. As needed: If pressure drops 10% at a known flow, check for filter loading or zone changes before blaming the pump. Preventive steps keep the Predator Plus delivering designed pressure and protect the Pentek XE motor from heat cycles and overloads.
How does Myers’ 3-year warranty compare to competitors and what does it cover?
Myers’ 36-month coverage is among the best in category. Many competitors offer 12–18 months, with complex claim paths. Myers covers defects in materials and workmanship for the term, assuming proper install. Combine that with serviceable design, and minor issues don’t force full replacements. From a risk standpoint, three irrigation seasons of coverage shifts meaningful liability away from your balance sheet. I’ve processed claims with PSAM where stock on hand kept customers running while paperwork finalized—exactly the support farms need.
What’s the total cost of ownership over 10 years: Myers vs budget pump brands?
Budget pumps may cut year-one cost by a few hundred dollars, but I routinely see 3–5 year lifespans under agricultural cycling, plus higher power use from efficiency drift. A Predator Plus running near BEP with a Pentek XE motor often saves 15–20% on energy and avoids at least one mid-decade replacement. Add reduced downtime costs—missed irrigation windows, labor, emergency service—and the math is decisive. On farms like Lucas Olander’s, a Myers setup outperforms on both reliability and dollars-per-gallon delivered across the decade.
