Power Units

with energy-saving intermittent cycling

Application
These power units are especially suitable for the operation of small to medium-sized hydraulic clamping fixtures.
Maximally 2 clamping circuits for single or double-acting cylinders are available, that can be controlled independently of each other. Thereby also "shuttle machining" is possible, i. e. that during machining of the workpiece in one fixture, workpiece change on the second fixture can be made.

Description
A special feature is the mounting of pump and electric motor in the reservoir. Thus hydraulic and electric control can be arranged in a space-saving way and easily accessible on the reservoir cover. The modular design enables a multitude of control variants. 
The radial piston pump is available with three different flow rates and operating pressures.
To allow an energy-saving intermittent cycling only leakage-free poppet valves are used.

Energy-saving intermittent cycling
The electric motor is only running, as long as hydraulic oil is really required, that means to

• extend and retract the clamping cylinder
• build up the operating pressure

Advantages

• Very compact design
• Energy-saving intermittent cycling
• Many control variants
• Electronic pressure switch
• Digital pressure display
• Quick pressure adjustment by teach-in function
• Electric control optimally adapted
• High-quality leakage-free poppet valves
• Pressure generator also without valves available
• Useful accessory already mounted
• Alternatively manual switch or foot switch
• Ready for connection
