The Penn Valley Double Disc™ pump incorporates a patented repair-in-place hinged housing that allows complete servicing without disturbing the suction or discharge 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, thickener feed, thickened sludge, primary sludge, scum and septage. The Double Disc® pump is self-priming and able to handle high suction lifts as well as being able to run dry without the risk of damage. Our “unique” design does not rely on close tolerances within the pumping chamber thereby eliminating the high maintenance costs associated with other positive displacement pump styles. 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 with our product, such as: trial purchase programs, rebuild/exchange programs, portable and trailer mounted units, custom configurations to fit existing installations, and same day shipment for all spare parts.
