The Liberty Pump 253-3 is an automatic, submersible effluent/sump pump that 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". This Liberty effluent/sump pump also has 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" and features a piggy-back plug allowing for manual operation. This effluent sump pump is ideal for pumping of drainage, effluent and waste water and other non-explosive/corrosive liquids.


The Liberty 253-3 effluent sump pump operates at 115V, 5.2 Amp and 60 Hz with a maximum fluid temperature of 140F. This Liberty sump/effluent pump is the perfect choice for low-head effluent pumping or basement de-watering applications, as well as liquid waste transfer for residential or commercial applications that require more flow at low-head. The powerful heavy-duty motor on the Liberty 253-3 effluent sump pump comes with a rugged housing and powder coat finish that is completely submersible and will provide years of reliable performance.
