Liberty Pumps LSGX203M is a 2HP 208-230V 2-Stage High-head Manual Submersible Grinder Pump (3 Phase) with 25ft quick-disconnect power. 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 progressive cavity style pumps have been required. It has better cutting, more flow with the same pressure, and greater reliability. With proven V-Slice cutter technology, the Omnivore Grinder Pump LSGX203M decomposes sanitary waste into a fine slurry allowing it to be pumped through a small diameter pipe, eliminating costly gravity systems with larger pipes 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. They 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 265°F regulations.
