Baffle Valve Pumps for Media Containing Solids

 

For pumping semi-solid media with a maximum diameter of 2" (51 mm) and solids up to 3/4" (19 mm)

ARO® flap valve pumps are designed for fluids that can only be pumped to a limited extent with conventional check valve pumps. These include fibrous, abrasive, or slurry-like liquids, as well as fluids containing large solids.

The flap valve design ensures a stable pumping process even with both suspended and free-flowing solids. With effective flow rates of up to 651 l/min, these pumps are suitable for rugged industrial applications involving demanding media.

  • Pumps with flap valves can be used in the following areas:
  • Drainage
  • Water treatment
  • Transfer of bulk materials
  • Filter press feed
