The Liberty Pump FL51M-2 is a manual submersible effluent sump pump with a 1/2 HP, 115V motor and a 25' quick disconnect power cord. Semi-open impellers, on the Liberty FL51M-2, permit the passage of 1/2" solids without clogging. This effluent sump pump has a discharge of 1-1/2"FNPT. This sump/effluent pump 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 the Liberty FL51M-2 effluent sump pump shuts off, at least 3-1/2" of fluid is left in the basin so the impeller remains submerged.
The Liberty Pump FL51M-2 manual submersible sump/effluent pump is ideal for mid-range applications and has a shut-off head of 48'. These effluent sump pumps are designed for STEP systems, liquid waste transfer and higher head de-watering applications.
