Liberty Pumps LSGX202A is a 2HP 208-230V 2-Stage High-head Automatic Submersible Grinder Pump with 25ft quick-disconnect power cord and piggy-back wide-angle float switch (adjustable). The turn-on level is 15" and turn-off level is 8".

With twin stainless steel impellers driving flow to maximum heads of over 180 feet, the LSGX Grinder Pump can be installed in applications where traditional progresssive cavity style pumps have been required. It has better cutting, more flow with the same pressure, greater reliability.


With proven V-Slice cutter technology, the Omnivore Grinder Pump LSGX202A macerates sanitary waste into a fine slurry allowing it to be pumped through small diameter pipe - eliminating costly gravity systems with larger pipe and deep trenching.

The LSGX-Series curve provides superior flows over a wide range of typical pressures - necessary for multi-unit developments and "large-area" low pressure sewer systems. The 2-stage Liberty Pumps LSGX202A allows installation of a centrifugal design where progressive cavity style pumps have traditionally been installed.


Liberty LSGX-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 guide 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 LSGX202A Grinder Pump features internal capacitors and does not require a separate control panel for operation.
