Hyvair Piston Pump 33 GPM – PCP33-3K-4CK-2AS-2

The Hyvair PCP33-3K-4CK-2AS-2 piston pump delivers up to 33 GPM at pressures to 3000 PSI, making it a powerful choice for demanding industrial hydraulic systems. Engineered for continuous-duty performance, this heavy-duty axial piston design provides stable flow and pressure for presses, injection molding machines, test stands, and other high-pressure applications where reliability is critical.

Featuring an ISO C 4-bolt mounting flange and a 1-1/4″ keyed shaft (3″ long with 5/16″ key), the pump integrates easily into standard power units and existing equipment layouts, reducing installation time and retrofit costs. A 1-1/2″ SAE inlet and 1-1/2″ SAE outlet provide generous porting for efficient oil flow, helping minimize inlet restrictions and cavitation in high-output systems. The #12 female SAE case drain connection ensures proper housing drainage and cooling, extending seal and bearing life under continuous load.

The PCP33-3K-4CK-2AS-2 is built around a pressure-compensated, adjustable-flow design that automatically matches output to system demand. This helps lower heat generation, reduce wasted horsepower, and improve overall energy efficiency, especially in circuits with varying duty cycles. By maintaining consistent pressure with variable flow, the pump supports smooth machine operation and precise control of actuators.

Backed by Hyvair’s reputation for rugged construction and dependable service life, this 33 GPM piston pump is an excellent upgrade from gear or vane pumps when you need higher efficiency, tighter control, and long-term durability in industrial hydraulic power units.
