Rotary Vane Mag-Drive Pumps, Warrender, WMRA, WMRP, SeriesRotary Vane Pump Models

WARRENDER, LTD produces the technically-superior WMRA pump range that is unique in both design and operation. The WARRENDER WMRA rotary vane seal-less mag-drive pumps are suited for low flow – high pressure applications, high-pressure systems or where metering is required.

The integration of zero-leakage magnetic couplings eliminates the need for mechanical seals or packing glands, thus significantly reducing the need for costly and time-consuming maintenance as well as process contamination. This high pressure pump range enables you to comply with the latest toxic emissions regulations.

The WARRENDER WMRA 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 WMRA pumps are capable of self-priming from a dry start.

Rotary Vane Pump Features:

  • High-head, low-flow functionality minimizes bypass requirements

  • Does not need priming and can run dry without damage

  • Heavy-duty alloy casing and containment shell

  • No gears to wear or metal-to-metal shearing, low internal slip

  • Capable of proportional operation with variable-speed drive component

  • Chemical resistant carbon or silicon carbide sleeve bearings

  • Quick-change rear cartridge assembly allows ease of servicing and reduces maintenance costs

  • High-torque magnetic couplings eliminate need for soft-starting motors

  • All ports are raised-face 150 lb. or 300 lb. ANSI flanges (600 lb. and 900 lb. are also available)
