Goulds 2DM51F3NA - 1-1/2 HP 230V Three-Phase Submersible Sewage Pump

The Goulds 2DM51F3NA is a 1-1/2 HP, 230V three-phase submersible sewage pump from Goulds 2DM Series, part of Xylem’s Goulds Water Technology line. It is rated to handle solids up to 1-3/8" spherical (1/2 HP) or 2" spherical (3/4 HP and larger) through a 1-1/2" (1/2 HP) or 2" NPT (3/4 HP and larger) discharge, running at 3450 RPM. The table below shows this pump’s flow rate at four fixed total dynamic head (TDH) points, so you can match it to your specific lift and distance requirements.

Applications: Simplex and duplex installations in small lift stations, drainage systems, or raw-water applications for homes and farms, mobile home parks and motels, schools and hospitals, municipal package systems, industrial treatment systems, and dewatering.

Warnings: This pump must be connected to electrical service protected by a Ground Fault Circuit Interrupter (GFCI) where required by code. Failure to do so may result in serious personal injury or death and property damage.

Do not run this pump dry for extended periods or operate it outside its rated flow and head range. Follow the manufacturer’s wiring, grounding, and float-switch/control-panel instructions for your specific installation.
