Flow Diffusers


  • Can be mounted horizontally in tank with discharge side facing away from suction
  • Discharge side should be pointed towards the tank wall or tank bottom
  • Can be highly effective in reducing aeration, foaming, turbulence and noise caused by return lines
  • Flow rates to 300 gpm


Flow diffusers are for hydraulic high-speed return lines, to slow down fluids entering the reservoir. They help cure foaming problems and prevent cavitation caused by flow disturbance at the pump inlet. They allow greater freedom in reservoir design and may even eliminate the need for tank baffling plates. They also reduce reservoir noise.

Our flow diffusers are rugged, high-performing products for a wide variety of hydraulic systems. We’ve got the right diffusers to protect your machinery, and if we don’t, we will make it for you through our custom, integrated manufacturing process.


  • These flow diffusers may be ordered with nut or nipple connector upon request
  • Pleated screen available for return line filtration upon request
