Compact hydraulic power pack type HK and HKF

Product description

The compact hydraulic power pack type HK and HKF consists of the tank, the integrated motor and the radial piston or gear pump directly attached to the motor shaft. The compact design that this achieves is a crucial advantage compared to conventional hydraulic power packs. A fan, which effectively dissipates the heat from the hydraulic system, is mounted on the housing. In the case of type HKF, the fan is powered by a separate motor independently of the pump motor.

Single-circuit, dual-circuit or triple-circuit systems can be assembled. A radial piston pump, an external gear pump or an internal gear pump can be used as a hydraulic pump. Compatible, ready-for-connection, complete solutions can be assembled easily using a wide range of connection blocks and the valve banks that can be combined with them.

Features and benefits:
  • Environmentally friendly thanks to low oil filling volume; low cost of disposal and low hydraulic fluid costs
  • Long service life and high reliability
  • Suitable for nominal operating modes S1 (continuous operation), S2 (short period operation), S3 (periodic intermittent operation) or S6
  • Speed control possible with frequency converter
Intended applications:
  • Clamping systems and tool loaders in lathes
  • Test bench construction
  • Material testing machines
  • Renewable energy plants
  • Welding machines and robots
