View all specifications

The Oilgear PFBK fixed displacement, axial piston pump is a mid-sized, high-pressure, dual discharge pump capable of delivering up to 1000 bar of continuous working pressure.

With providence in multiple tough environment applications including, high pressure test rigs, die-casting and injection moulding, intensifier systems, extrusion press systems, forging processes, civil projects, and a broad variety of metal forming systems.

The PFBK range features a single high-pressure outlet port to insure high speed operation. The swash plate is installed at 13 degrees which provides a very low piston head loading to improve load and wear on the pump.

Through drive options are easily achieved with the PFBK meaning you can mount additional pumps with up to 37.3 Kw capacity. 

All Oilgear pumps are designed to thrive on low-viscosity fluids that feature a higher water content such as Skydrol™, Stack Magic™, Erifon™ and 98/2.

As with all Oilgear pumps, all contact surfaces such as the cylinder surface running on the valve plate and the pistons running on the swash block surface are all hardened for incredible durability.

Within the PFBK series, we can offer a displacement range of  35- 68cc/rev.

Pump Specifications:

  • Circuit Type: Open loop
  • Fluid Type: Hydraulic, low lubricity
  • Displacement: 44.7cc/rev
  • Max Continuous Pressure: 700 Bar
  • Max Speed: 1800 RPM

High pressure, quiet in operation, super high efficiency, compact design, competitive pricing, and impressive lead time are the key attributes of the Oilgear PFBA piston pump. Available in 4 displacement sizes, the PFBK is your go to selection for high pressure systems running with low viscosity fluids.

Standard Features:

  • Six hardened steel pistons operate within a stationary block (with no centrifugal force) which massively reduces wear and load
  • Each of the steel pistons are hydrostatically balanced which reduces piston wear, allows for a higher-pressure operation, and permits use of low viscosity fluids
  • Single hardened swash plate for incredible wear resistance
  • Both the inlet and outlet check valves are seated in such a way for

Product Options:

  • Integrated boost
  • Thru-shaft availability for driving multiple pumps from a single power source
  • 4 different seal options
  • Left- or right-hand rotation
  • SAE A or B mounting flange
