Specifications for P-Series Servo Power Unit Only Option
The Servo Power Unit (SPU) is sized based on the customer’s cylinder flow & pressure (speed / load). As a note, most HPUs have a max PSI (e.g. 1500psi or 3000psi). Sizing based on that alone may increase the overall sizing and costs.
Knowing the specific PSI at the cylinder provides the optimum sizing. Having the cylinder’s bore, rod & stroke plus monitoring a pressure gauge and possibly taking a video of the cylinder in operation (for speed) is all you need to size an SPU.
Definitions
| Pump Size: | Pump identifier |
|---|---|
| Gallons/Liters Per Minute: | desired flow (gpm/lpm) |
| Max Working Pressure: | maximum working/operating pressure (psi/bar) |
| Required Torque: | the required motor torque (based on the max working pressure) |
P-Series Power Unit Only is available only with customer supplied motor & drive.

Notes:
**Torque Information for customer-supplied motor & drive instances
- Can be used with most any double-acting cylinder / rod combination
- The factory requires the rod & cylinder diameter and stroke length to properly size
- Cylinders are required to be filled with the factory standard fluid following the factory’s procedure
- This is a Representative Sample of the Servo Power Unit Product Range, Consult Factory for Additional Models
- For additional information on the Operational Performance of Servo Power Units, speak with an Engineer
Servo Power Units are configured to adapt with your cylinder size and performance requirements for force and speed.
Our standard Servo Power Unit provides a maximum of 9.88 cc/revolution (7.8 GPM) at 3,000 PSI
