The Liberty 251-3 Pump is an automatic, submersible effluent/sump pump. It features a 1/3HP motor that can produce a flow rate of 36 GPM at 10' and includes a wide-angle float switch. This switch has an "ON" level at 11" and "OFF" level at 4.2". This effluent sump pump is ideal for pumping of drainage, effluent and waste water and other non-explosive/corrosive liquids. The Liberty 251-3 effluent sump pump comes with a 35-ft. power cord and has a shut-off head of 23'. It has a 1-1/2" discharge and can handle solids up to 1/2".


The Liberty 251-3 effluent sump pump operates at 115V, 5.2 Amp and 60 Hz with a maximum fluid temperature of 140F.
