Compact hydraulic power pack type HK and HKF

Product description

Compact hydraulic power packs are a type of hydraulic power pack. They are characterised by a highly compact design, since the motor shaft of the electric motor also acts as the pump shaft.

The ready-for-connection compact hydraulic power pack type HK, HKF, HKL and HKLW includes an electric drive which runs in oil. The stator is securely attached to the housing (tank). The compact hydraulic power pack is suitable for hydraulic systems with operating mode S2, S3 or S6.

The compact hydraulic power pack type HK, HKF, HKL and HKLW is suitable as a highly compact control system, since connection blocks and valve banks can be directly mounted.

Features and benefits:
  • Suitable for continuous operation with intermittent load S6 and continuous operation S1
  • Additional external fan for optimum use of power
  • Wide range of applications, with three sizes available
  • Long lifetime and excellent reliability thanks to use
    of radial piston pumps
  • Environmentally friendly thanks to low oil filling volume; low cost of disposal and low hydraulic fluid costs
  • Tailored range of valves and accessories from modular system
  • One-circuit to three-circuit pumps available
Intended applications:
  • Clamping systems on machine tools and turning centres
  • Handling and clamping systems on machine tools and fixtures
  • Welding machines, robots
  • Endurance test bench construction
  • Hydraulic torque wrenches
