Rotary Vane, Seal-Less, Mag-Drive Pumps, Warrender WMDAVRotary 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.

Features:

  • Self-Priming and can run dry without damage

  • No gears to wear or metal to metal contact, low internal slip

  • Capable of proportioning with variable speed drives, turn-down ratios depend upon differential head requirements

  • Heavy duty alloy containment shell for added safety

  • Replaceable carbon cartridge-low maintenance costs

  • High torque magnets for direct starting motors

  • Internal relief valve prevents over pressurization
