Rotary Vane Seal-Less Mag-Drive Pumps

The WARRENDER WMRA Series Alloy P.D. Rotary Vane Seal-Less Mag-drive Pumps (superseding the WMDAV) 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 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 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

Technical Data:

• Flow: .1-11 GPM (22-2500 M³/H)
• Head: To 180 psig (12 bar)
• Temp: To 450°F (to 232°C)
