Liberty Grinder Pumps
Liberty grinder pumps handle raw sewage that standard sewage pumps cannot, using a cutting mechanism to macerate solids, rags, and fibrous materials into a fine slurry before pumping through small-diameter pressure lines. This makes grinder pumps the right choice when the discharge line is too small or too long for a conventional sewage pump to push whole solids through reliably.
Common grinder pump applications include residential low-pressure sewer systems where each home has its own grinder pump that pushes sewage through a 1-1/4" to 2" pressure line to a community collection point, basement bathroom additions where a long or small-diameter discharge run to the main sewer makes a standard sewage pump impractical, and remote buildings far from the sewer main.
Liberty grinder pumps are available in a range of horsepower and flow capacities. Select based on the total dynamic head (vertical lift plus friction losses in the discharge line), the discharge line diameter, and the number of fixtures connected to the system. For complete installations, consider a Liberty grinder system package that includes a matched basin, pump, and controls.
