Rotary Vane Pump Guide Sliding Vane Pump Design

The sliding vane pump design makes them generally unsuitable for high viscosity applications, as a thick liquid would prevent the vanes from moving in and out of their slots with ease. In addition, their very tight tolerances mean that solids cannot pass and will jam the vanes; hence them being suited to relatively clean liquids.

What Are Vane Pumps?

13/09/2019  The pump is fitted with a relief valve to prevent the pump from building to a pressure which may damage the pump. The pump head contains a slotted rotor which contain vanes. The vanes create segmented chambers within the pump head, partitioning the pump head between the rotor and outer casing which enable the vane pump to be self-priming as the chambers operate similar to valves.
