  • Quick And Dirty Guide to Vane Pumps - Crane .

    Each type of vane pump offers unique advantages when it comes to specific applications. For example, an external vane pump is great for handling large solids. On the other hand, flexible vane pumps can only handle small solids, but create a good vacuum. Sliding vane pumps can run dry for short periods of time and handle small amounts of vapor.

  • A Great Lie About Hydraulic Pumps | Hydraulics & .

    2017-8-3 · Accordingly, conventional wisdom suggests that outlet pressure is not required for a vane pump to prime. The centrifugal force on the vanes sets up the initial seal to allow the pump to draw fluid from the reservoir. In fact, in the literature for Rexroth's PV7 vane pumps, it clearly states: "All PV7 vane pumps are self-priming".
