The Liberty Pump FL152M is a manual submersible effluent sump pump with a 1-1/2HP, 230V motor that is enclosed in heavy-cast iron construction. The Liberty FL152M submersible sump/effluent pump is equipped with a dual sized discharge of 1-1/2" FNPT and 2" FNPT for connection to either size pipe. This effluent sump pump can also handle solids up to 3/4" and has a shut-off head of 110'. The Liberty FL152M is intended to be run using an approved liquid level control or approved motor control with correct rating that matches motor input in full load amperes. Regardless of the control type, be sure that when this effluent sump pump shuts off, at least 3-1/2" of fluid is left in the basin so the impeller remains submerged. These Liberty effluent pumps are designed for STEP systems, mound systems, liquid waste transfer and higher head de-watering applications.
