Flanged Chemical Diffusers

Multi-Orifice Design

FLANGED MULTI HOLE DIFFUSER flanged injectors & diffusers

Flanged diffusers are designed to fit into a flanged additive port. The diffuser flange is sandwiched between the flanged port and a mating blind flange or flanged pipe.  They provide an easy method of distributing chemicals throughout the entire pipe diameter.

Sized for each application, they will include a multitude of orifice holes along the injector. 

These smaller holes distribute chemicals throughout the pipe. Long service life with low maintenance-scaling liquids not issue due to thin wall/large diameter 

As these chemical diffusers can be designed to be supported at both end of the pipe, PVC, Kynar and Teflon diffusers can have much longer solution tubes than the typical cantilevered unsupported diffuser.   

Teflon diffusers are an excellent choice for concentrated sulfuric acid injection!

Chemical diffusersare available in a variety of materials including:

  • Teflon
  • Kynar
  • 316L S.S.
  • Hastelloy C-276
  • Titanium
  • PVC
  • CPVC 
  • Fiberglass

supported PVC diffuser

For longer length diffusers constructed from plastics, such as PVC, we can provide a metal support tube which allows for longer unsupported lengths.  Ideal for larger pipelines and channel diffusers that require both a longer diffuser and the corrosion resistance of plastics.  Great for Chlorine solutions, dilute acids, etc.
