Class 125 Suction Diffusers

Series 1011 Class 125 Suction Diffusers provide economical and compact pump protection by straining foreign particles and providing proper flow conditions to the pump. This series mounts directly to the suction side of a pump in either the horizontal or vertical position.


  • Straightening vanes on outlet side reduces turbulence into pump, minimizing stress and erosion within pump
  • Reduces installation cost and joint leak paths because one unit acts as elbow, strainer, and entry pipe to the suction side of the pump
  • Knobs open quickly for easier maintenance access
  • O-ring seal eliminates need to clean sealing area and install a new flat gasket
