Features and Benefits

The Wilden® Accu-Flo Velocity Series is the solenoid option for the compact air-operated double-diaphragm (AODD) pump. Featuring a unique detachable mounting foot, Velocity Series pumps can easily be reoriented into a vertical or horizontal position with multiple inlet and discharge port options, a critical consideration for systems and skids.
  • Numerous mounting configurations to fit any application
  • 5.1 m (16.9') dry suction lift for better priming
  • Startup pressures as low as 1.03 bar (15 psig)
  • Bore-seal design that eliminates leaks that result from torque decay
  • Interchangeable footprint with previous Wilden designs (P.025, P25)
