Submersible effluent pump for residential drainage

The Zoeller N152 is a submersible effluent pump built for handling liquid waste in residential sump or septic systems. Its cast iron body and thermoplastic impeller resist corrosion during continuous immersion. Rated at 4/10 hp and 8.5 amps on 115 V AC, it suits typical household effluent duties.

Maximum head of 38.0 feet determines installation

The pump develops a maximum head of 38.0 feet, which is the single figure that decides whether it can lift effluent to the discharge point. At 10 feet of head it delivers 61.0 gpm, falling to 53.0 gpm at 15 feet and 44.0 gpm at 20 feet. Performance drops to zero beyond the rated maximum head.

Handles up to 61.0 gpm at low head.

The unit comfortably moves up to 61.0 gpm when discharge head stays near 10 feet, making it suitable for standard basement or crawl-space sumps. Flow declines steadily as head rises, and the pump cannot overcome elevations greater than 38.0 feet. It requires a minimum sump pit diameter of 18 inches and 18 inches of water depth for proper operation.

Questions about this item

What does the 4/10 hp rating mean for actual pumping performance?

The 4/10 hp motor delivers 61.0 gpm at 10 ft of head, 53.0 gpm at 15 ft, and 44.0 gpm at 20 ft, with a maximum head of 38.0 ft.

How does the 115 V 60 Hz single-phase supply limit installation options?

The pump requires a standard 115 V AC, 60 Hz, single-phase circuit and draws 8.5 amps, so it must be wired to a compatible household or light-commercial supply.

What size sump pit is needed for the 10 3/32 in diameter body?

The minimum sump pit diameter is 18 in, and the pump needs at least 18 in of water depth to operate properly.
