The Liberty Pump LE51M is a manual submersible sewage pump with a 1/2, 115V motor and a 10' quick-disconnect power cord. This Liberty sewage pump is capable of reaching a max flow of 112 GPM at 25' total dynamic head. This sewage 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.

Smooth running, Solidly Built Pump
By Newbee Homeowner (from Chicago, Il) on 2/2/2016
I bought this pump to replace a Champion CWP 1/2 hp sewage pump. The champion's vertical float failed 1 month into operation so I replaced it with a tethered float. The motor started to go bad 1 year and 1 month after installation the pump was drawing 3 amps more than it should and rumbling (The pit was drained, no load on pump, no obstructions in pump or piping). I talked to a different plumber (one who didn't sell me a stale dated pump) and recommended liberty pumps. The pump is controlled by the tethered float and works very well and is much quieter. The feature that convinced me to buy a liberty pump was the stainless steel shaft. Being in sewage a steel shaft may corrode damaging the seal and bearing which could lead to shortened pump life. Too new to give it 5 stars.
