STRAINERS

Model SA Suction Diffuser

Save time. Save money. Save space. Provide smoother flow conditions for the pump. Our suction diffuser eliminates the need for a long pipe entrance, pipe saddle and floor flange, so it is faster to install.

It also features a throwaway start-up diffuser screen, a necessity for hydronic systems and closed or domestic water systems. Remove it after start-up without losing the protection of the larger perforation in the orifice cylinder. Its angle body provides an elbow which facilitates a close transition between system return piping and the system pump suction. Some models even perform as reducing elbows.

Other features:

  • Full-length straightening vanes assure uniform flow pattern
  • Easily removable end cap
  • Pressure gauge tapings permit checking of system conditions
  • Plug/blow down connection permits routine maintenance
