This quarterly technical session hosted online will cover the topic of piston pumps and load sense controllers. The session will be presented by Ian Lavington - fitter and turner by trade with 26 years experience with Commericial Intertech followed by 2 years with Parker followed by running his own business in Western Australia selling gear pumps.

The webinar, hosted by Fluid Power Society of WA will be over Zoom with live engagement during the presentation. RSVP below to receive the details to join the event.

The webinar link using Zoom will be emailed out to the participants who have RSVP'd here prior to the event.

Post event notes:

1. Follow-up questions

Question: Can you please clarify the RPM question regarding pump efficiency?

Answer: The maximum piston pump speed depends on displacement. A 5cc pump can rev up to 6000rpm whereas a 1000cc pump has a max speed of 950rpm. The minimum speed depends on output pressure as efficiencies especially volumetric are high at low speeds. Generally you would not run a axial piston pump below 100rpm and an external gear pump below 500rpm.

Question: Is standby and differential pressures the same value?

Answer: The bias spring of the pump is on-top of the differential pressure of the pump. The bias spring is required to get the pump to swash on.
