The 281 from Liberty Pumps is an Automatic Sump/Effluent Pump w/ Wide Angle Float Switch, 10' cord, 1/2HP, 115V. It features a unique one-piece cast iron housing and thermally protected & permanently lubricated motor.
The switch of this pump is factory-preset and is not adjustable. Turn-on level of the switch is 13-1/2" and turn-off level is 7". Other pumping differentials may be obtained by tethering the switch cord to the discharge pipe. NOTE: A minimum cord length of 3-1/2" from the tether point to the top surface of the float is required for proper switch operation. If using a differential other than the factory setting, 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.
Liberty Pumps 281 has 1-1/2" NPT discharge, 3/4" solids-handling and 37' shut-off head.
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.
