Rotary Vane Seal-Less Mag-Drive Pumps:
The WARRENDER WMDAV Series Alloy P.D. Rotary Vane Seal-Less Mag-drive Pumps are ideally suited for low flow / high pressure applications including chemical injection and metering systems. All WMDAV pumps are equipped with zero leakage magnetic couplings to meet the latest toxic emissions regulations. The WMDAV pumps feature self-compensating sliding-vanes which maintain design head and flow capacities for extended operating life. The WMRA pumps are suitable for thin non-lubricating liquids and/or high differential head pressures. The pumps are capable of self-priming from a dry start.
