PFBK-033 Fixed Displacement Piston Pump

Oilgear PFBK-033 Fixed Displacement Axial Piston Pump is designed for applications that require high-pressure capability, constant flow output, and long-term durability. The displacement of 33 cc/rev results in strong hydraulic performance with great suitability for industrial systems that call for reliable and repeatable flow under grueling working conditions.

Part of Oilgear's robust PFBK series, the PFBK-033 is designed to operate under continuous high pressures and is therefore best fitted for heavy-duty hydraulic systems such as metal forming equipment, high-pressure lubrication circuits, forging and extrusion machinery, hydraulic power units, and special industrial tools. Due to its fixed-displacement structure, it provides a consistent flow output during every revolution, which, in return, makes it reliable in applications where predetermined flow and stability are required.

Inside the PFBK-033, a rugged rotating assembly is supported with hardened wear surfaces, precision bearings, and a durable swashplate mechanism. These components work in concert to minimize internal wear, reduce friction, and provide smoother hydraulic operation over extended duty cycles. Oilgear's design also enhances contamination resistance, enabling the pump to perform reliably even in systems where fluid conditions can vary.

This model is engineered for a wide range of hydraulic fluids, including standard oils, low-viscosity formulations, and certain specialty fluids. Compatible with modern hydraulic oils, it ensures that lubrication remains stable and service life is extended, even under the most demanding applications or in high-temperature environments. The construction of the PFBK-033 supports excellent efficiency, reduced noise levels, and dependable flow delivery over a broad operating range of speeds.

The pump has a compact, practical footprint that can be easily integrated into a variety of existing machinery or newly designed hydraulic systems. The multiple shaft options, mounting configurations, and porting arrangements provide flexibility for installation and help the engineers in designing an efficient hydraulic circuit with no compromise on space or performance.
