MA0419X-12A Well Pump Review: Pumps 33 GPM for 5-Inch or Bigger Wells

The MA0419X-12A in Short

If your well uses a 3.8″ pump body and you need a 2-wire setup, the fit decision starts with diameter and wiring, not with price.

MA0419X-12A Deep Well Submersible Pump fits that situation with 2 HP and a built-in control box, and it does not require an external one. Its 110V 60HZ supply and stainless steel construction are part of the same package.

We screened 107 Well Pumps and this is one of 15 chosen for a full review. Full reviews go to the most-rated products that pass screening, at most 2 per brand. This one has 398 buyer ratings, the 12th most of the 107 screened.

The Short Answer on the MA0419X-12A

Best for: you need a deep-well pump that can handle a 2-wire setup and a 1-1/4 NPT discharge.

Choose the MA0419X-12A if you want 2 HP, 35 GPM, and 400 feet of head for a system that needs higher lift and stronger flow; it’s around $185.

• Pro: Its 35 GPM rating supports multiple fixtures at once in a larger home.
• Pro: The 400-foot head rating suits wells that need substantial vertical lift.
• Con: The 1-1/4 NPT discharge rules out buyers who need a different outlet size for existing plumbing.
• Con: The 3.8-inch pump diameter limits you to wells that can accept that size, so it is not a universal fit.

Don’t buy this if: your well or plumbing needs a discharge size other than 1-1/4 NPT, or your casing cannot accept a 3.8-inch pump.

Price assessment: $185 is fair for a 2 HP deep-well pump with 35 GPM and 400 feet of head.

Key Specifications

Maximum head is the deciding spec that separates this pump most clearly. Head measures the greatest vertical lift the pump can overcome while moving water.

Before You Buy: Well Pump Checklist

The first thing to check is whether your well casing and discharge line match this pump’s 3.8-inch body and 1-1/4 NPT outlet. If either side is wrong, you may need to return it or rework the plumbing before it can fit.

• ☐ Confirm your well casing size — 5″ or bigger wells are stated here, and a smaller casing can leave you with a pump that will not fit.
• ☐ Check the discharge connection — 1-1/4 NPT is the outlet size, and a mismatch can force a return or incompatible plumbing changes.
• ☐ Measure your required lift — 400 Feet is the stated maximum head, and a deeper lift need can leave you with pressure that never reaches the tap.
• ☐ Budget for the wiring setup you want — 2-wire pump and built-in control box are both stated, so you may avoid a separate control box; if your system needs different wiring, you will need another pump.
• ☐ Check whether your household demand fits the output — 35 GPM is the stated flow rate, and a mismatch can leave you with short-cycling or a system that cannot keep up.
• ☐ Measure the space for the pump body — 3.8″ is the stated diameter, and a tighter bore can make the pump unusable in your well.

Do not buy this pump if your well is smaller than 5 inches, your discharge plumbing is not set up for 1-1/4 NPT, or you need a different wiring arrangement.

What the Numbers Mean in Use

Flow Output

When your well needs to serve several fixtures at once, MA0419X-12A gives you 35 GPM of flow output. That rate is the figure that matters for house demand and for irrigation demand, because it tells you how much water the pump can move in a minute. At 35 GPM, it supports a larger home without forcing you to treat every tap as a separate load.

The 400-foot maximum head is the other half of the decision, because it measures how far the pump can lift water vertically. If your well is deep, that number is what keeps the flow from becoming useless at the tap. The 1-1/4 NPT discharge also matters here, since you need your plumbing to match that outlet size before you order.

Power Supply

MA0419X-12A uses a 2 HP motor on 110V, so it is aimed at buyers who need more lift than a light-duty well pump. That power level supports deeper wells and longer runs, which is why it matters when your water level sits far below the pump intake. The 2-wire setup also keeps the control side simpler, since the listing says it does not require an external control box.

The 10-foot power cord is short enough that you should plan around the wellhead layout before buying. The pump diameter is 3.8 inches, and that is the size you need to compare with your casing and clearances. The listing also states compatibility with 5-inch or bigger wells, so the opening in your system has to match that fit before the pump can be a realistic option.

How thermal protection and stainless steel reduce overheating

MA0419X-12A includes built-in thermal protection, which matters if you want a pump that can protect itself from overheating under load. That feature is especially relevant in deeper wells, where long runs put more stress on the motor. The stainless steel construction also gives you a corrosion-resistant material choice for a wet environment.

The built-in check valve keeps water from flowing back through the pump after shutdown, which helps the system hold prime and reduces backflow in the line. Thermal overload protection is stated separately in the listing, so you get another layer of motor protection beyond the thermal feature already named. If your setup depends on a pressure tank, you should still confirm that the tank and switch are sized for 35 GPM, because a mismatch can shorten cycle times even when the pump itself is protected.

How the MA0419X-12A Compares to Alternatives

MA0419X-12A gives you the strongest headroom in this comparison, with 2 HP, 35 GPM, and 400 feet of head. That is the kind of spread that matters when a well needs both lift and usable flow.

• Kailaidi SHYLIYU Submersible Bore Pump lists 0.5 HP, so MA0419X-12A brings far more motor power for deeper or heavier-demand jobs.
• ECO LLC Submersible Bore Pump uses a 1/2 HP motor and states 8 GPM, while MA0419X-12A states 35 GPM. That wider flow figure is the clearer fit for running several fixtures at once.
• Acquaer CJE075-1 is a 3/4 HP pump with a dual-voltage motor, so it suits buyers who value the voltage flexibility more than the larger power rating here.
• DRUMMOND Stainless Steel Shallow Well Pump lists 115.5 feet of total head lift, while MA0419X-12A states 400 feet. Think of head like how high a hand truck can carry a load up a ramp; this one handles the steeper climb.
• ZYIY Stainless Steel Deep Well Submersible Pump uses 0.75 hp and 18.5 GPM, so MA0419X-12A keeps more margin for higher-demand household use.

Pick Acquaer CJE075-1 instead if dual-voltage wiring matters more than raw pumping figures. Its 115V/230V motor gives you a different compatibility path that MA0419X-12A does not state.

Getting the MA0419X-12A Working, and What to Check After

Getting MA0419X-12A ready for a 110V supply

MA0419X-12A needs a 110V, 60HZ power source before it can move water.

1. Confirm a 110V, 60HZ supply is available at the installation point.
2. Match the discharge connection to 1-1/4 NPT before the pump is set in place.
3. Check that the well opening is at least 3.8 inches across, since the pump diameter is 3.8 inches.
4. Use the built-in control box for the 2-wire motor, so no external control box is needed.
5. Set up the line for a 10-foot power cord if the outlet sits close to the well head.

Warranty and support: what to check for MA0419X-12A

Warranty cover varies by seller and country.

• Confirm the return window for a 2-wire pump, because the built-in control box and thermal protection affect what you can replace easily.
• Confirm who covers shipping on a 3.8-inch, stainless steel pump, since returning a heavy deep well unit can cost more than smaller parts.
• Confirm whether the 1-1/4 NPT discharge fitting is covered if it arrives mismatched, because that connection has to fit your system.
• Confirm whether electrical support covers a 110V, 60HZ motor, since the pump will not be usable with the wrong supply.

On the day it arrives, inspect the box for the 110V, 60HZ rating, the 1-1/4 NPT discharge, and the 2-wire control box before the return window closes.

What Buyers Still Want to Know About This Well Pump

Is a 2-wire pump easier to wire than a 3-wire one, and does that matter for my setup?

Yes, a 2-wire pump usually means fewer external parts than a 3-wire setup, because the control box is not separate. MA0419X-12A states a 2-wire motor and says it does not require an external control box, so that wiring choice matters if you want a simpler parts list. A 3-wire setup can still suit some jobs, but this listing does not state one here.

Choosing the wrong wiring type can cost you time and a return if the pump does not match the control gear you already plan to use. MA0419X-12A is the 2-wire option in this section, so you should match your setup to that format before ordering.

Final Verdict on the MA0419X-12A

You need a 2-wire deep well pump with 400 feet of head and 1-1/4 NPT discharge, and the MA0419X-12A fits that job. Around $185 makes it a straightforward option if your well setup calls for that combination.

The 35 GPM flow rate is the strongest number here. That output matters when you want one pump to support multiple fixtures without short-cycling the system, and the 2 HP motor gives it room for deeper well work.

Skip it if: you need a 3-wire submersible setup with a separate control box, or your plumbing calls for a discharge size other than 1-1/4 NPT.
