The Liberty Pump FL102M is a manual, 1HP, 230V submersible effluent sump pump that is enclosed in heavy-cast iron construction. The Liberty FL102M 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 90'. The Liberty FL102M 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. The Liberty FL102M is built of heavy cast iron with an epoxy powder coat finish and stainless steel fasteners.
