• The PAR-range of hydraulic power supplies offers high hydraulic and electrical efficiency with infinitely variable flow control through variable displacement pump system with additional essential features.
• The PAC-range of hydraulic power supplies are equipped with high-pressure internal gear pump providing constant oil supply and operates at a continuous (adjustable) pressure. These pumps are versatile, providing a very high overall efficiency, have very good pulsation behaviour and operate at low noise emission. Internal gear pumps further have a straightforward and rugged construction that guarantees long service life without the need of extensive maintenance.

All our Hydraulic Power Units /HPUs) are compatible with our servohydraulic dynamic and fatigue testing systems and servohydraulic components for component testing and load simulation. These Hydraulic Power Packs contain a number of essential standard features that makes these units tailor-made for the challenging requirements of servohydraulic test systems working with high responsive servo valves.  

• Long-life and low noise internal gear pump
• Oil tank with vertical mounted motor-pump group
• High Energy Efficient motors comply with European Standard IEC 60034-30-1 with Premium Efficiency IE3 level.
• High-pressure inline filter with clogged filter indication
• Long oil change & filter element intervals
• Compensation of pressure losses
• Designed for serviceability and safe operation
• Pump protected against over-pressure through pressure limiter valves. One fixed to protect system over-pressure one adjustable
• Oil-Tank with cleaning cover for easy servicing
• Damping ring between motor and pump top separate of structure-borne noise between drive unit and tank
• Totally enclosed and noise-isolated version
• Air fan on the rear side of the power pack to avoid high air temperature inside the power pack
• Electric pressure indicator for safety mode in case of failure of a hose, pipe etc.
• Max. oil temp. protection (shut down of the system)
• Adjustable minimum oil level indication (shut down of system)
• Oil pressure manometer on front panel
• Oil temperature indication on front panel
• Motor power indication with electrical safety mode
• Hour meter
• Fluid level gage
• Filler
• Remote turn on/off control of hydraulic through testing software
• To lower the power consumption and to safe operating expenses the power pack includes a pressure control valve which allows to lower the system pressure (if the maximum force is not needed). Therefore, the power consumption will be less. A pressure manometer will indicate the adjusted pressure.
• Including oil water heat exchanger (cooler) to be connected to the cooling water supply (alternative re-cooler/chiller)
• Thermostatically operated water valve for minimum cooling-water consumption
• Meets ISO 4413:10 (Hydraulic fluid power - General rules and safety requirements for systems and their components and the European directive 2006/42/EC for machinery safety
