Liberty Grinder Pumps
Liberty Grinder Pumps
Patented V-Slice® cutter technology
PRG series pumps are a great replacement for troublesome sewage ejectors
3-year warranty
Liberty grinder pumps feature patented 440 stainless steel V-Slice cutters that deliver up to 108 alternated cuts per revolution. Cleanout slots and back relief clear debris from under the cutter to prevent clogs. Quick-connect power cords can be replaced in seconds without breaking seals to the motor.
PRG ProVore® pumps feature a 2" NPT discharge. They are an ideal replacement for sewage ejectors that struggle with clogging. Piggyback-style float switches make installation easy.
LSG200 Omnivore® pumps offer upgraded features for the most demanding applications. Their cutting system is hardened to Rockwell C58 for shearing solids into small particles under high pressure. One-piece unibody casting eliminates a leakage point between the top housing and volute. A dual shaft seal and 316 stainless steel impeller ensure long service life.
The GR20 guide rail system is exclusively for new installations of LSG200 pumps. It attaches to the two-bolt oval flange on an LSG200 pump and a single 1-1/4" guide rail pipe. The included upper rail support bracket improves stability.
