Machine Billet, Rotary Vane Seal-Less Mag-Drive Pumps, Warrender WMRARotary Vane Seal-Less Mag-Drive Pumps:

The WARRENDER WMRA Machined Billet Rotary Vane Seal-Less Mag-drive Pumps (superseding the WMDAV) are built for high system pressures and special alloy requirements. All WMRA 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 WMRA 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 pressures. The WMRA pumps are capable of dry self-priming.

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
