Working in Unison
As the suction disc lifts from its seat, a vacuum is created that draws fluid into the pump chamber. At the same time, the discharge disc remains seated to direct flow through the pump.
The Double Disc Pump combines positive displacement pumping with unique free-disc technology to deliver smooth, non-clogging flow. Two discs operate in unison as both pumping and valving elements, enabling reliable handling of solids, rags, slurries, and other difficult media while minimizing wear and maintenance requirements.
Pump Cycles
During discharge, pressure causes the suction disc to seat while fluid is pushed toward the outlet. This positive valving action helps maintain consistent flow, even with solids-laden media.
Small displacement per stroke
A short stroke length and small displacement per revolution create smoother flow than traditional reciprocating pump designs, making the technology suitable for sensitive transfer and dewatering applications
Solids, rags and plastics
Large disc openings allow solids, rags, plastics, and debris to pass without clogging, while low internal velocities help reduce wear when handling abrasive slurries and sludge.
Sealed fluid chamber
Flexible trunnions eliminate the need for packing, mechanical seals, lubrication, and flush water, providing a clean, leak-free design with minimal maintenance requirements
Priming and Re-Priming
Delivers strong dry-priming and re-priming capabilities, helping maintain dependable operation in dewatering, wastewater, and industrial transfer applications.
