Bieri Combination Hydraulic Pumps

Bieri BKP Combination Pump

This combination pump includes an external BRK radial piston pump coupled through a flange and onto the primary gear pump in a compact design that can be installed in any position with self-priming and venting capability. Perfect for use in two separate hydraulics circuits with different pressures and displacements. This combination can also be ordered with an MRK Multi-outlet radial piston pump. The part description would be MKP.

Bieri BKP combination hydraulic pump

Bieri KKP

This compact, light pump is well-suited to systems that require low flow rates in the high pressure area and high flow rates in the low pressure area. The Bieri KKP is self-priming and can be started at maximum pressure. Integrated safety features include a low-pressure unloading valve and a fail safe valve. A hollow shaft allows for direct mounting of
a motor without a bell housing and coupling.

Bieri SKP

This compact self-venting combination pump is available in a variety of combinations. It is intended for vertical installation in the oil reservoir and includes an integrated low-pressure unloading valve, a fail safe valve, and a hollow shaft for direct attachment of a motor without the need for a bell housing and coupling. Similar to the KKP, this pump is well-suited to systems that require low flow rates in the high pressure area and high flow rates in the low pressure area.
