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
  • Smooth control; eliminates abrupt flow changes and stress on hoses / connections
  • Dynamic Braking for smooth control with an over-riding load
  • High Efficiency
  • Network Connectivity
