Penn Valley Pump Co., Inc. manufactures the rugged and reliable Double Disc Pump which combines the performance features of a positive displacement pump and the principle of Induced Flow to provide superior versatility in fluids handling. Based on a Free Disc technology, the pump utilizes a unique principle of operation where the discs perform the duties of both diaphragm and valve, providing a double acting, non-clogging, pumping action. We are proud to be a past WEFTEC Innovative Technology Award Winner with this technology. Our unique design does not rely on close tolerances within the pumping chamber to generate flow which decreases wear. This reduced wear allows the pump to have the lowest life cycle costing of any positive displacement pump on the market and eliminates the high maintenance costs associated with other positive displacement pump styles. The pump incorporates a patented maintain-in-place hinged housing design that allows complete servicing without disturbing the piping. With flow rates ranging from 1-1,400 GPM, the pump is routinely used for sludge handling applications to include: belt press feed, centrifuge feed, rotary press feed, thickener feed, thickened sludge, digested sludge, primary sludge, FOG, scum, septage and more. The Double Disc Pump is self-priming, operates under high vacuum conditions and runs dry without damage. With no mechanical seals or packing glands and sealed for life bearings the pump requires no routine maintenance. We offer a variety of customer oriented programs to ensure your satisfaction without product, such as: Swap-Your-Pump free trial purchase program, rebuild/exchange programs for existing pumps, portable and trailer mounted units, custom configurations to fit existing installations, and same day shipment of all spare parts.
