PFBK-065 Fixed Displacement Piston Pump is a heavy-duty fixed-displacement axial piston pump designed to provide powerful and constant hydraulic flow under demanding conditions. With a displacement of 68.4 ml/rev, this pump supplies significant volume per revolution and is suitable for industrial presses, high-pressure test rigs, intensification systems, marine hydraulic systems, and other heavy-duty hydraulic applications.
The PFBK series includes a family of mid-size, high-pressure, fixed-displacement pumps for applications requiring consistent performance and long service life. The PFBK-065 operates on an open-loop circuit capable of handling continuous pressures up to 415 bar and is rated for a maximum rotational speed of 2400 RPM. These parameters make it a dependable choice for systems needing stable flow and pressure under continuous or heavy-duty cycles.
Inside, the PFBK-065 is designed to be rugged and dependable. It features solid build quality, hardened moving parts, and a robust valve arrangement that gives improved resistance to contamination and allows operation with low-lubricity hydraulic fluids. The fixed-displacement design ensures that each revolution of the shaft delivers the same volume of fluid-the best solution for applications needing predictable, repeatable hydraulic output.
With a high displacement and pressure capability, this pump drives large actuators, presses, and fluid-power systems requiring strong hydraulic force and continuous fluid delivery. Its compact footprint with flexible installation makes it suitable for both new installations and retrofit systems. The rugged construction and simple fixed-displacement operation lower maintenance needs, enable better contamination tolerance, and permit long service intervals.
The Oilgear PFBK-065 is a sturdy, reliable, and performance-oriented hydraulic pump for demanding use within the industrial and marine sectors. Here at Rexton Hydraulic, we supply, support, and service this pump to ensure proper selection, installation, and long-term maintenance so that your system will run smoothly and efficiently.
