Description

Liberty Pumps 257-2 is a 1/3HP Automatic Submersible Sump Pump with with magnetically operated vertical float VMF switch and 25ft power cord. Turn-on level of the not adjustable switch is 7" and turn-off level is 3-1/2". This pump can operate in a smaller 10" diameter sump pit..

The Liberty Pumps 257-2 has 1-1/2" NPT discharge, 1/2" solids-handling, 18' shut-off head, a unique one-piece cast iron housing and thermally protected & permanently lubricated motor.

This Vertical Magnetic Float (VMF) model is not recommended for effluent applications due to their short On/Off cycle. Wide angle float models (Liberty Pumps 251-2 and 253-2) are better suited for effluent applications and are easily adjustable for different On/Off levels.

For added protection, consider the addition of a back-up pump such as Liberty's SJ10 SumpJet, as well as an alarm such as Liberty's ALM-2 in applications where loss of pump function could result in property damage. If an alarm is used, it must be connected to a separate electrical circuit.

CAUTION: Do not let the pump run dry.
