The Liberty LE74M2-2 Pump is a 3-phase manual submersible sewage pump with a 3/4HP, 440-480V motor and a 25' quick-disconnect power cord. This Liberty sewage pump also has a 2" FNPT flanged discharge and a shut-off head of 28'. The Liberty Pump LE74M2-2 manual submersible sewage pump features rugged 2-vane, semi-open impellers that allow handling of 2" solids. The Liberty LE74M2-2 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. Be sure that when the Liberty sewage pump shuts off, at least 6" of fluid is left in the basin so the impeller remains submerged. Separate approved pump control device or panel is requires for automatic operation.

 

The heavy-duty built Liberty Pumps LE74M2-2 sewage pumps are ideal for residential and light commercial sewage applications. 3-Phase Liberty Pumps require panel for automatic operation. See sewage accessories literature for complete information on all simplex and duplex controls. Check three phase pumps for proper rotation prior to installing pump(s) in basin. To change rotation, reverse any two of the three power leads to the pump.
