What this pump does

The Myers MUFKP40 is a 4/10 HP plug-in utility pump rated for 115 V AC at 60 Hz. It draws 3.00 amps and uses a single-phase motor to move water in residential or light-commercial sump pits. The thermoplastic body and impeller resist corrosion while keeping weight low.

Flow at working heads

At 5 ft of head the pump delivers 42.0 gpm, at 10 ft it delivers 32.0 gpm, at 15 ft it delivers 22.0 gpm and at 20 ft it delivers 12.5 gpm. Maximum shut-off head is 25.0 ft. These figures let you match the pump to the actual lift and friction loss in your discharge line.

Install and common issues

The unit needs a sump pit at least 12 in diameter and a minimum water depth of 12 in. Body diameter is 10 in and the widest point is 12 in, so verify pit clearance before placing it. No switch is included; you must add a compatible float or pressure switch. The Buna-N shaft seal handles typical clean water but can degrade if abrasives or chemicals are present.

Questions about this item

How often should the Buna-N shaft seal be inspected or replaced on the Myers MUFKP40?

The Buna-N shaft seal is a wear part; plan to inspect it annually and replace it if leakage appears around the motor shaft.

What head height begins to limit flow most noticeably during continuous pumping?

At 20 ft of head the flow drops to 12.5 gpm, and the pump reaches its maximum head of 25 ft where flow stops.

How warm does the motor housing get when the pump runs all day at 3.00 amps?

The thermoplastic body stays warm to the touch but is designed for continuous 115 V AC operation at the rated 3.00 amp draw.
