Liberty Pumps 250 is a 1/3HP Manual Submersible Sump/Effluent Pump with 10ft quick-disconnect power cord. This Liberty Pump features a unique one-piece cast iron housing and thermally protected & permanently lubricated motor. Efficient motor design of this Energy Saving Liberty Pump reduces electrical usage by up to 40%.
Liberty Pumps 250 has 1-1/2" NPT discharge, 1/2" solids-handling, and 18' shut-off head. It is intended to be run using an approved liquid level control or approved motor control with a correct rating that matches motor input in full load amperes. Regardless of the control type, be sure that when the pump shuts off, at least 3-1/2" of fluid is left in the basin so the impeller remains submerged.
For added protection, consider the addition of a backup 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.
