This Dayton 4NY25 effluent pump delivers 1/2 hp at 120 V AC single phase. It moves clear or lightly contaminated liquids from sump pits with a minimum diameter of 4 in. The stainless steel body and acetal impeller resist corrosion in typical effluent applications. Rated current is 11 A.

Installers who need a manual pump without

The unit ships with no switch included, so external level control must be provided. It suits installations where a separate control panel or tethered float is preferred. Buyers who want an integral automatic switch must select a different model. The 4 in. body diameter fits standard 4 in. sump pits.

230 ft maximum head

The pump reaches a max head of 230 ft. At 60 ft head it produces 14 gpm, at 80 ft head 13 gpm, at 100 ft head 11.5 gpm and at 150 ft head 9 gpm. These flow points let you verify performance against the required system curve. Choose this model when the total dynamic head approaches the 230 ft limit.
