Features
- They feature a pressure flow compensator that automatically reduces (or stops) pump flow if the system pressure on the pump outlet port rises above a pre-set maximum pressure.
- They come with a polyacrylate shaft seal to offer excellent resistance to hot oil, automatic transmission and Type A power steering fluids.
- They have an oil-free design to prevent oil contamination that can cause damage to equipment.
- They also feature a low profile design to minimise the vibrational effect and allow noise-free operation.
Frequently Asked Questions
What mounting orientation is used for open-circuit piston pumps?
These pumps can be mounted in any position with the help of the mounting hub and two-bolt mounting flange (in conformance with SAE standards).
What is cavitation?
Cavitation occurs when there is a very low suction pressure, causing erosion to the metal surfaces due to the vapour bubble collapsing, allowing the liquid to rush into the subsequent spaces at high velocity and creating water hammering.
What is a suction static head?
It is the height difference between the surface of the inlet reservoir and the centreline of the pump.
