The new ProVore PRG-Series grinders from Liberty Pumps are designed for use in residential applications where addition of a bathroom or other fixtures below sewer lines requires pumping. The unit, powered by a 1-horsepower motor, is designed to operate on 115 or 230 volts and can be plugged into standard 20 amp circuitry. The ProVore features Liberty’s patented V-Slice cutter technology, which easily shreds solids such as feminine products, rags and other unwanted debris. Compact factory-assembled systems are available in both simplex and duplex versions.
