Hawe Hydraulic Power Packs

Hawe Hydraulic Power Packs KA and KAW Series

Compact hydraulic power packs are characterised by a highly compact design, as the motor shaft of the electric motor also acts as the pump shaft. The compact hydraulic power packs Type KA and KAW include an electric motor that runs in oil. The stator is securely attached to the housing (tank). These power packs are suitable for hydraulic systems with operating modes S2, S3, or S6. Heat is dissipated via surface convection, so an external cooler is typically not necessary.

For systems with high loads, an external fan for additional heat dissipation can be optionally mounted on the housing. Type KA features a 3-phase motor, while Type KAW includes a single-phase motor. Both KA and KAW types are available in horizontal and vertical versions. A radial piston pump or external gear pump can be used as the hydraulic pump. These compact power packs are ideal for highly compact control systems, allowing direct mounting of connection blocks and valve banks.

Features and benefits:

Additional separately driven fan for maximum power utilisation

Modular tank extensions for flexible fill/usable volumes

Long lifetime and excellent reliability through radial piston pumps

Environmentally friendly due to low oil fill volumes and reduced disposal/hydraulic fluid costs

Coordinated range of valves and accessories from a modular system

Suitable for both vertical and horizontal installation

Optimal efficiency via suboil motor cooling, direct force transmission, and smart heat dissipation

Intended applications:

Brake and rotor adjustment modules on wind turbines

Clamping systems on machine tools and appliances

Torque wrenches

Riveting and clinching equipment

Presses

Handling systems
