  • Drain port: ½” clamp connection for drain valve (drain valve NOT included)
  • Pump outlet: Standard (vertical) or turned 45°C left.

 

 

Theory of Operation

The W+ pump series is based on a proven hydraulic design that promotes high operational efficiency and reduces noise and vibration levels while maintaining hygienic standards.

Low viscous fluids enter through the center inlet and flow around the impeller which turns at various speeds based on application requirements. The fluid then moves to the outer extents of the impeller vanes by centrifugal force and is directed through the outlet. As with other SPX FLOW centrifugal pumps, impeller and casing designs are optimized to perform more efficiently over a wide range of operating conditions. The casing and port are further designed to maximize performance under low NPSH conditions.

  • 1 - Unique spiral volute positioned in the back plate of the pump ensures a direct transfer of liquid from inlet to outlet
  • 2 - Advanced, high efficiency impeller design
  • 3 - Extended outlets smooth transition to process piping while reducing turbulence and preventing product build-up
  • 4 - Heavy walled pump casing insures that efficiency levels are maintained even at high pressure
