Product Category

Series SR
Warrender Series SR alloy centrifugal Mag-drive pumps provide the advantages of a heavy-duty seal-less process pump in a compact, cost effective design. SR 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.

 

Features
  • Seal-less magnetic drive coupling
  • Rugged alloy casing and pump components
  • Heavy duty alloy containment shell
  • High efficiency enclosed impeller design
  • Silicon carbide sleeve vs. carbon journal bearings with intermittent dry-run capability
  • High torque magnets suitable for direct starting motors
  • Close-coupled NEMA motor frame or bearing pedestals
