Penn Valley Pump offers seven different Double Disc Pump™ sizes that are ideal for use in the municipal, industrial, chemical and food processing industries. The company’s unique pumps combine performance features of a positive displacement pump, with principles based on ‘induced flow’, that allows for superior versatility in fluid handling. All pumps are designed using a ‘Free Disc” technology, as well as a unique principle of operation where discs perform the duties of both the pumping element and valving element, creating a double-acting, non-clogging, pumping action.
