Liberty Pumps LSG204M is a 2HP 440-460V Manual Submersible Grinder Pump (3 Phase) with 25ft quick-disconnect power cord.

Liberty's LSG200-Series Omnivore grinder pumps meet the demanding needs of commercial and residential sewage applications where difficult solids-handling ability is crucial.

Superior cutting system of the Liberty Grinder Pumps LSG204M provides improved shredding performance over radial cutters. V-pattern provides up to 108 alternated cuts per revolution. The entire cutting system made of 440 stainless steel hardened to 58Rc. Recessed cutter bolt eliminates wadding Exclusion cleanout slots and back relief clears debris from undercutter.

Liberty LSG-Series Grinder Pumps are designed for continuous underwater operation. The motor and pump form a close coupled, watertight unit. The induction motor is insulated against heat and moisture in accordance with Class B 265F regulations.

The Omnivore Grinders may be guided rail mounted using Liberty's GR20 guide rail base, or stand-alone.

Liberty Pumps G90 Flanged Elbow provides vertical discharge for non-guide rail installations.

The Liberty LSG204M Grinder Pump features internal capacitors and does not require a separate control panel for operation.

NOTE: Requires a separate approved pump control device or panel for automatic operation. Operation of these models will be according to the control selected. Make sure the electrical specifications of the control selected properly match the electrical specifications of the pump. Always refer to control panel instructions for proper installation.

3-phase models require a properly sized control panel. Check three phase pumps for proper rotation prior to installing pump(s) in basin.
