Electro-Hydraulic Power Unit for use with Customer Cylinders

The Servo Power Unit (SPU) was developed as an alternative to the SMART Electro-Hydraulic Actuator (SHA) for those instances where the All-In-One SHA is not able to fit in the available space envelope. The SPU provides many SHA benefits including: precise position, speed and force control, compact size, and high force density. It connects to a customer-supplied cylinder through robust quick connect fittings. The SPU can be located close to the cylinder reducing footprint and reducing hose length.

Servo Power Unit Features:

  • Servo controlled
  • Works with most any cylinder
  • Standard ISO 16028 3/8” cylinder connections
  • Up to 9.88 cc/rev fluid flow at 3,000 PSI
  • Network Connectivity
  • Smooth control; eliminates abrupt flow changes and stress on hoses / connections
  • Dynamic Braking for smooth control with an over-riding load
  • High Efficiency

servo power unit overview


  • The Servo Power Unit (SPU) combines proven technologies into an innovative new power unit with servo actuation control.
  • Provide energy saving power-on-demand unlike traditional hydraulic power units.
  • The compact size allows the SPU to be located very close to the cylinder reducing losses and improving control.
  • Has built-in precision servo control of position, force and speed.
  • Ideal in rugged applications that damage and cause pre-mature failure with ball screw/roller screw actuators.
  • Simple setup and integration with common networks, including CanBus, Ethernet, Modbus and others.
  • Comes as a complete package, factory-tuned and ready to install saving hours of time
