Product description

Notes

For converting HK PVPC axial piston pumps to pressure regulators with load sensing function (type L)

Description

The delivery volume of the pump is automatically regulated to generate a flow rate with a constant pressure drop (independent of the load) via a throttle.
The pump flow rate is continuously regulated by changing the throttle.
The load sensing control system always includes a hydraulic expansion joint to limit the maximum pressure.
Adjustment range of the expansion joint:
20 - 280 bar (type HK PVPC 3029, 4046, 5073)
20 - 250 bar (type HK PVPC 5090)
Standard setting of the expansion joint:
280 bar (type HK PVPC 3029, 4046, 5073)
250 bar (type HK PVPC 5090)
Differential pressure adjustment range: 10 - 40 bar
Standard differential pressure setting: 14 bar
