Range Filtration

Suction Diffusers

Removes Large Particle Impurities in Pipeline Systems

A suction diffuser combines an elbow and built-in strainer with flow straightening at the pump suction inlet. It simplifies installation, reduces space and fitting requirements, and eliminates the need for an equivalent length of ten pipe diameters of straight run on the pump suction side.

Design features

  • Available with RF and FF flange
  • Full Length Straightening Vane Assembly ensures uniform flow tothe suction inlet of the pump
  • Metering Port allows for the monitoring of system conditions
  • Disposable Fine Mesh Start-Up Strainer promotes cleaner more trouble free system
  • Removable Cover Plate and reusable O Ring allows for easy access and maintenance of Permanent Strainer
  • Blow Down port allows for routine maintenance and removal of sediment and debris
  • Fabricated design.Can also be Ductile Iron Body on all units
  • Optional Magnetic Insert totrap small metallic particles
  • Installed for perpendicular alignment
  • Drain connections are standard and are furnished with plug.
  • Drain can be provided with product on request.
  • Oversized Body Cylinder ensures minimal pressure drop
