Dayton 11A342 Grinder Pump 16 ft Single 230V AC 2 hp

Application and Suitability

The Dayton 11A342 is a 2 hp grinder pump rated for 230V AC single-phase power at 11 A. It delivers 47 gpm at 10 ft of head, 50 gpm at 15 ft, 46 gpm at 20 ft, 38 gpm at 40 ft, and 20 gpm at 60 ft. Designed for residential or light commercial sewage handling where solids must be macerated before discharge.

Electrical and Piping Verification

Confirm the supply circuit provides 230V AC at 60 Hz with capacity for an 11 A motor load and appropriate single-phase wiring. Verify the discharge piping is sized for the rated flow rates and that the system head falls within the 10 ft to 60 ft performance range. No switch or level control is included, so a separate actuation method must be supplied.

Construction and Connection Implications

The stainless steel body resists corrosion in sewage environments while the ductile iron impeller withstands abrasive solids. Carbon, ceramic, and silicon carbide shaft seal materials provide durability against gritty fluids. Without a factory-fitted switch, the installer must integrate a compatible float or pressure control, and the 16 ft power cord length determines placement relative to the electrical supply.
