Application: PD45 Axial Piston Pump

     A 'very quiet' pressure compensated pump was required for use on a piece of laboratory equipment. The target sound level was below 83 dB(A) and the flow had to be 20 GPM at 4,000 PSI. This is 50 horsepower! Parker’s PD45 (2.7 cubic inch / revolution) axial piston pump held the solution. Not only does it have a cast iron housing; but, it incorporates their “Ripple Chamber” technology engineered into the side ported pump. The ripple chamber reduces pressure pulsations (called ripple) at the outlet of the pump by 40-60%. This leads to a significant reduction in overall system noise, without the added expense of noise dampening components. The pump was powered by a 1,800 RPM electric motor. At this speed the pump produces a sound level of 76 dB(A). Through the use of this pump and correct power unit construction, the customer’s expectations were met.
