Hawe

HAWE Hydraulik is a German company and specialized manufacturer of compact hydraulic components and systems for industrial and mobile applications. With over 75 years of experience, HAWE delivers high-quality radial piston pumps, directional control valves, pressure relief valves, proportional valves, hydraulic power units, and complete hydraulic systems renowned for their exceptional power density and reliability.

The unique characteristic of HAWE products is their compact design: HAWE's radial piston pumps (R, K series) are the smallest high-pressure pumps in their power category, operating up to 700 bar with very small dimensions. This makes HAWE systems ideal for applications where space is limited: machine tools, test benches, medical equipment, aerospace, and mobile machines.

The HAWE range includes radial piston pumps (R, RZ, K series), axial piston pumps, gear pumps, directional control valves (WN, E series), proportional valves (PSVP, PSV series), pressure relief valves, power units, and complete hydraulic units. HAWE's compact valve blocks (DSV) are unique in the industry, combining multiple functions in an extremely compact unit.

HAWE's electronically controlled hydraulic systems, including EHC (Electronic Hydraulic Control) modules, offer digital proportional controllers, CANbus communication, and diagnostic capabilities for modern mobile machines and test equipment.

At Verkopershulp.nl we carry over 2,336 genuine HAWE parts. As an authorized distributor we guarantee fast delivery, technical support for system selection and configuration, and full warranty on all HAWE products.

History

HAWE Hydraulik was founded in 1949 in Munich, Germany by Karl Heindl. The company pioneered compact high-pressure hydraulics with the development of its signature radial piston pumps. The focus on high pressure in compact dimensions distinguished HAWE early from other hydraulic manufacturers producing larger, heavier systems. From the 1960s to the 1980s HAWE expanded its product portfolio into directional valves, proportional valves, and complete hydraulic power units. The company broadened its distribution network throughout Europe and later into North America and Asia. Key markets were the machine tool industry and later medical technology. Today HAWE has its headquarters and manufacturing in Munich with an international network of distributors in more than 70 countries. The company is investing in digital hydraulics, energy-efficient systems, and IoT connectivity for the next generation of hydraulic control.

Frequently Asked Questions

What makes HAWE radial piston pumps special?
HAWE radial piston pumps are characterized by exceptionally high pressure (up to 700 bar) in an extremely compact design. The radial configuration of the pistons provides lower pulsation and more uniform flow output than axial pumps. HAWE pumps are self-priming, quiet, and offer long service life due to their robust construction. They are ideal for applications where space and weight are critical.
Which HAWE valve is suitable for proportional flow control?
HAWE PSVP proportional valves provide direct proportional control of flow rate relative to electrical control current. The PSV series offers pilot-operated versions for higher flow rates. HAWE's electrically controlled WN series provides on/off directional valves for simpler switching tasks. For advanced servo-like control, HAWE proportional valves with integrated position sensor are available.
Are HAWE valves directly mountable on standard ISO 4401 mounting plates?
Many HAWE directional valves are designed for mounting on ISO 4401 (CETOP) standard mounting plates and are therefore interchangeable with valves from other manufacturers. HAWE also offers its own DSV compact valve blocks that integrate multiple valves in one compact unit, minimizing pipe connections and simplifying installation.
What is the working pressure of HAWE hydraulic systems?
HAWE hydraulic components are designed for working pressures up to 700 bar, significantly higher than most standard industrial hydraulics operating at 200-350 bar. This makes HAWE systems suitable for applications requiring high force in small volumes, such as press applications, bolting technology, and hydraulic test benches.
Are HAWE components suitable for use with biodegradable hydraulic fluids?
Yes, many HAWE components are compatible with biodegradable hydraulic fluids such as HEPG (polyglycol) and HETG (triglyceride vegetable oil). Always check the HAWE compatibility guide for the specific component and fluid type, as some seal materials are not suitable for all synthetic fluids.
How do I maintain a HAWE hydraulic power unit?
Maintenance includes periodically checking the oil level, replacing the hydraulic filter (typically every 1,000-2,000 operating hours), replacing the hydraulic oil (annually or per 2,000 hours for mineral oil), and inspecting seals and couplings for leakage. HAWE supplies overhaul kits per power unit model. Verkopershulp.nl stocks all required parts.
Does Verkopershulp.nl supply HAWE accumulator parts?
Yes, we supply HAWE hydraulic accumulators (bladder and diaphragm accumulators), accumulator bladders, shut-off valves, and safety blocks. HAWE accumulators are available in volumes from 0.16 to 50 litres for working pressures up to 350 bar. Specify the model number and required volume/pressure for the correct accumulator selection.
Which communication protocols do HAWE EHC modules support?
HAWE EHC electronic control modules support CAN J1939, CAN SAE J1939, and CANopen communication protocols for integration into mobile machine control systems. Analog 4-20 mA and 0-10V inputs are standard. Digital I/O for sensors and actuators is also integrated. HAWE supplies configuration software for setting EHC parameters.
