PFBK-043 Fixed Displacement Piston Pump

The PFBK-043 is a sturdy, fixed-displacement axial piston pump that has been designed for heavy-duty hydraulic systems running under continuous high pressure and hard operating conditions. This heavy-duty axial piston pump provides strong volumetric flow per revolution at 44.7 ml/rev, and hence, it is fit for high-pressure test rigs, industrial presses, intensifier units, marine systems, and such heavy-duty operations.

This pump has an open-loop circuit and is able to support a continuous maximum pressure of 700 bar. It can run at speeds up to 2400 RPM, combining high flow capacity with stable continuous operation-a key advantage for systems that run for long hours under tough loads.

Inside, the PFBK-043 uses a rugged, stationary-cylinder design with hardened pistons and durable valves, ensuring a long service life and resistance to wear. The fixed displacement and robust poppet-type valve construction offer excellent contamination tolerance, even when using low-viscosity or specialty hydraulic fluids. This construction makes the pump ideal for extreme environments, fluctuating loads, and heavy-duty hydraulic tasks.

Because the displacement is fixed, the pump delivers a constant, repeatable flow with each shaft revolution — giving your hydraulic system a stable, predictable output. That reliability is critical in applications requiring a high degree of accuracy, pressure consistency and repeatability. The pump’s simplicity also minimizes maintenance complexity and helps minimize your chances of downtime.

PFBK-043 supports flexible integration; it is designed to mount and configure easily in new systems or during retrofitting of existing setups. It fits very well in the intensifier units, forging presses, test benches, marine hydraulic systems, and industrial machinery wherever high pressure and steady flow matter the most.
