Mini hydraulic power packs

With their highly compact, weight-optimised design, mini power packs are designed for a wide range of applications. They provide a flow rate from 0,24 lpm to a maximum of 4 lpm. The portfolio includes hydraulic power packs from simple holding functions in reversing mode, simple lifting/lowering functions to special power packs for safety brakes for cranes, lifts and winches.

Mini hydraulic power pack type HR050

In this mini power pack, our well-proven radial piston pump from automotive engineering is integrated directly into the bell housing. As oil tank the unit has a round transparent tank with a M8x1 filler plug.

Technical data

Flow rate: max. 1 l/min
Operating pressure: max. 200 bar

Mini hydraulic power pack type HR080

The type HR080 micro hydraulic power pack features high pressure in the smallest space, with the option to use any installation position. The reversing function is performed by reversing the direction of rotation of the motor. A directional valve is not needed. The motor is protected from overload by an integrated temperature switch. This hydraulic power pack is equipped with a DC or AC motor.

Technical data

Operating pressure: max 210 bar
Flow rate: max. 0.52 l/min
Tank volume: 0.3 L
Weight: 4 kg

Mini hydraulic power pack type A

The mini hydraulic power unit type A is characterized by its modular design. In the power pack, an external gear pump is flanged to the equipment carrier and the oil reservoir is designed as a round plastic tank with an M 14x1.5 filler plug. The power unit is mainly used in automotive engineering, aviation, floor-lock systems as well as in decentralized hydraulic control systems.

Technical data

Max. operating pressure: 210 bar
Max. flow rate: 3 lpm
Use volume: 0.2 - 0,8 l

Mini hydraulic power pack type HICON

The compact hydraulic power pack type HICON’s encapsulated design offers protection against temporary immersion in water according to protection class IP 67. The pump module integrates a gear pump and a brushless motor. The motor's rotation can be reversed, thus facilitating low reversion without requiring a directional valve. When designing the compact hydraulic power pack type HICON, particularly emphasis was placed upon status monitoring. The integrated temperature switch protects the motor from overloading.

Technical data

Max. operating pressure: 170 bar
Geometric displacement volume: 0.5 cm3/rev
Use volume: 0.6 l

Directional valves

Directional seated valves have zero leakage. Depending on the valve type, actuation is electromagnetic, pressure-actuated, mechanical or manual. The range includes seated valves and valve combinations. Directional spool valves are also a type of directional valve. They control the direction of movement and the velocity of single and double-acting hydraulic consumers. The range includes on/off directional spool valves, proportional directional spool valves and valve combinations.

Valve bank (directional seated valve) type SLC1

The SLC1 chained valves are a combined design consisting of seated valves and dual check valves. They can be used to hold hydraulic actuators in position for long periods of time. Restrictor check valves are mounted on the cylinders for speed adjustment.

Technical data

Flow rate: max. 1 lpm
Operating pressure: max. 150 bar

Valve bank (directional spool valve) type TLC3

The TLC3 series connection add-on valve is a combined design consisting of a slide valve and a dual check valve. It can be used to hold hydraulic actuators in position for long periods of time. The built-in T-throttles also allow the user to pre-set the speed of the actuators.

Technical data

Flow rate: max. 3 lpm
Operating pressure: max. 250 bar

Accumulators

Various fittings are available for hydraulic accessories, which are used to connect these hydraulic devices to the pressure lines of HAWE hydraulic power packs and valves in various assembly situations. Piston type accumulators are a type of hydraulic accumulator. A freely moving piston separates the compressible gas cushion from the hydraulic fluid.

Diaphragm accumulator type AC

The diaphragm accumulator type AC is used as a source of pressurized oil. It supports or increases the pump delivery flow or stores pressure energy, e.g. for an accumulator charge circuit. The type AC is available as a miniature hydraulic accumulator. It is particularly suitable for usage in clamping hydraulics. It is used there to compensate for volume changes in the event of temperature fluctuations, to cover any leakage losses or to dampen oscillations.

Technical data
