Grinder Pumps are ideal for residential and light commercial sewage transfer and are designed to handle the same type of materials as a sewage ejector pump but can pass more challenging solids. If you are pumping to a pressurized sewer main, pumping a very long distance, or have a high vertical height required to lift the sewage, then a Grinder Pump with a minimum of 2 HP will most likely be required. If, on the other hand, you have an existing effluent or sewage pump struggling with clogs or binding, Little Giant's new 1 HP Grinder Pump is the ideal drop-in replacement. Regardless of your system's specific grinding needs, we have a solution for every contractor and homeowner!
