Rotary Vane Mag-Drive Pumps:
The WARRENDER WMDAV Series Alloy P.D. Rotary Vane Seal-Less Mag-drive Pumps are ideally suited for low flow / high head applications. The top porting design is ideally suited for a confined piping system. All WMRA 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 WMDAV pumps are suitable for thin non-lubricating liquids and/or high differential pressures. The pumps are capable of self-priming from a dry start.
