Have you ever had the experience of something going down the toilet that shouldn’t have?  Uh Oh!  Now you are faced with an overflowing toilet full of disgusting water, and if that wasn’t bad enough, now you are slapped with gigantic plumbing bills for repairs.  Here at, we don’t want you to flushing away your hard earned money; we want you to keep that money in your pocket.  We offer some of the lowest prices on the market!  If you are ever in this situation where you are not sure what people are throwing down the toilet, chances are you need a grinder pump.  A Grinder Pump does as the name suggests, it grinds up the wastewater produced in a home or business and pumps it into the sewer or septic system.  There are many manufacturers that offer grinder pumps, but only one stands above the rest: Liberty.  Liberty Grinder Pumps are perhaps most famous on the market due to their innovation technology and patent designs.  

Liberty features 2 distinct lines of Grinder Pumps, the PRG Series and Omnivore Series. 

The PRG Series are designed for sewage applications.  With a higher flow rate, this allows use with 2” discharge lines.  This PRG Series operates on standard 115 or 230 volt, 20 amp circuits, and features a heavy cast iron construction with a patented V-Slice cutter technology.  This technology is able to shred difficult solids such as feminine products, rags, towels and wipes that can jam a solids-handling style pump.  The PRG-Series grinders can be used as replacement pumps in 2” discharge systems using LE40 and LE50 series solids-handling pumps. 

The other Liberty Grinder Pump line is the Omnivore Series.  This Series is built for commercial grinding applications, while the ProVore is designed to handle waste solids found in residential systems (such as sanitary wipes). The Omnivore LSG stands out beyond most manufacturers, due to Liberty’s patented V-Slice cutter technology.  This superior cutting system, is made of hardened 440 stainless steel for shearing solids into small particles prior to being passed to the discharge by the impeller under high pressure.

The Omnivore Series also features the LSGX Series.  These pumps are built to provide economical, environmentally friendly solutions for multi-unit low pressure sewers.  Liberty has gone above and beyond in creating the LSGX Series.  These pumps feature twin stainless steel impellers, which drive flows to maximum heads of over 180 feet, making  the LSGX the perfect fit to be installed in applications where traditional cavity style pumps have been required.  The superior cutting of the patented V-Slice technology is paired with pumping performance that rivals traditional progressive cavity style pumps.  The Omnivore macerates sanitary waste into a fine slurry, allowing it to be pumped through a small diameter pipe and eliminating costly gravity systems with larger pipes and deep trenching. With this technology, engineers have the freedom to replace restrictive gravity style systems with cost effective Omnivore-drive low pressure sewer systems.
