Features
- Their compact design allows installation in space constraint areas, delivering more power than standard pumps.
- They feature a saddle-type swashplate with steel-backed polymer bearing to allow continuous operation, extending the pump's service life.
- They have a unique tapered design that reduces vibrations and features an optional power control to aid the machine in using power more accurately.
Frequently Asked Questions
What is a pressure compensator spool?
The compensator spool consists of a plunger that slides in a cylindrical barrel that automatically reduces (or stops) pump flow if system pressure on the pump outlet port rises above a predetermined maximum pressure.
How to install the open circuit piston pump?
- Install the piston pump in such a position that the case drain maintains an oil level at or above the unit centre line.
- Oil level must be at the centre line or above before starting the piston pump.
- Provide a case drain line of adequate size to limit the case pressure to 25 psi (maximum).
- Ensure that the combined torque required to turn two or more pumps must not exceed the torque rating of the input drive shaft of the front piston pump.
What is the purpose of valves in these piston pumps?
These pumps feature valves for maximum heat transfer and protect the valve seats from dust and contamination.
