PFBK-052 Fixed Displacement Piston Pump

Oilgear PFBK-052 pump is designed to meet the demands of heavy-duty hydraulic systems for reliable, fixed-flow output with strong pressure capacity. This model ensures substantial fluid volume per revolution, with 54.5 cc/rev displacement, which will be a sure support in applications related to industrial presses, test rigs, intensifier systems, marine hydraulics, extrusion or forging equipment, and other demanding hydraulic applications.

This pump belongs to the fixed-displacement series PFBK, characterized by high-pressure operation and long service life. It supports open-loop circuits and is engineered to sustain 700 bar of continuous pressure while operating at speeds up to 2400 RPM. Such specifications make it capable of managing heavy work and continuous duty cycles with stable flow and consistent performance.

Internally, the design of the PFBK-052 includes a robust, stationary piston cylinder configuration with hardened pistons and a rugged valve arrangement. This provides minimum wear, offers greater contamination resistance, and holds performance consistent under extreme ambient conditions. Fixed-displacement construction also assures constant, repeatable flow with each revolution — which is important in applications where a high degree of accuracy, pressure stability, and repeatability are important.

The pump provides ease in system design with its robust construction and fixed output, since less complexity in the control is needed when compared to variable-displacement pumps. With a stable flow and pressure, this type of pump is ideal for hydraulic presses, high-pressure test benches, marine hydraulic systems, extrusion/forging machines, or any system where a reliable, steady hydraulic supply is critical.

Whether for powering heavy machinery, upgrading an existing hydraulic system, or building a new high-pressure hydraulic circuit, the PFBK-052 offers a strong balance of flow volume, pressure capability, durability, and service life. At Rexton Hydraulic, we supply, install, maintain, and service the full PFBK series to make sure your pump performs reliably under demanding conditions.
