Product Features & Fitment

This submersible effluent pump features a rugged, corrosion-resistant cast-iron housing designed to withstand harsh environments while offering excellent structural stability. The heavy-duty plastic impeller allows the system to easily process spherical solids up to 3/4 inch in diameter, making it ideal for graywater and pre-filtered wastewater systems. Driven by a powerful 230V motor drawing 12 amps, this pump manages an impressive 5,500 GPH flow rate and handles an exceptional maximum vertical lift of up to 109 feet at 47.25 PSI—providing a strong solution for long-distance or high-head pumping demands.

Please note that this model features a switchless design, requiring an external control panel, liquid level control, or piggyback float switch for automated operation. The unit is built with a threaded female outlet connection and a long 20-foot power cord, fitting seamlessly into standard configurations down to an 11 to 14-inch minimum basin diameter.
