Our Rotary Vane pumps feature self-compensating sliding-vanes which maintain design head and flow capacities for extended operating life. This high pressure pump range is suitable for thin non-lubricating liquids and / or high differential pressures. The RV pumps are capable of self-priming from a dry start.
ROTARY VANE PUMPS
Machined Billet Rotary Vane Seal-less Mag-Drive Pumps (superseding the WMDAV) are built for high system pressures and special alloy requirements. All WMPA pumps are equipped with zero leakage magnetic couplings to meet the latest toxic emissions regulations. The absence of mechanical seals eliminates costly pump maintenance, lost production time and process contamination. The WMPA pumps feature self - compensating sliding-vanes which maintain design head and flow capacities for extended operating life. The WMPA pumps are suitable for thin non-lubricating liquids and/or high differential pressures. The WMPA pumps are capable of dry self-priming.

machined thermoplastic self-priming rotary vane seal-less Mag-drive pumps (MP Series) are positive displacement pumps intended for low-flow / high head applications, high-pressure systems or where metering is required. CNC machined from solid Simona polypropylene or polyvinylidene fluoride (PVDF, Kynar), WMRP Machined In-Line pumps are extremely resistance to internal or external corrosion, permeation and migration of solvents and corrosive. WMRP Machined In-Line pumps can handle pressurized applications and are capable of dry starting. Zero-leakage operation ensures maximum safety and full compliance with toxic emissions regulations.
