The 280-2 from Liberty Pumps is a Manual Sump/Effluent Pump, 1/2HP, 25' cord, 115V. It features a unique one-piece cast iron housing and thermally protected & permanently lubricated motor.

Liberty Pumps 280-2 has 1-1/2" NPT discharge, 3/4" solids-handling and 37' shut-off head. It 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. 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.

Use for De-watering, Sump and Effluent Applications.

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.
