N°5 – Circulators training – NVQ Level

Circulators (small wet rotor pumps) are all of the in-line type. Their light weight allows direct installation on the pipe between union connections or between flanges.

We recognise:

  • Fixed port to port dimension models :

Even though non-standard, the port to port dimension on small “domestic” circulators used by all manufacturers is 180 [mm].
For specific applications, such as fitting wall mounted boilers, even smaller devices exist.

Port to port 180             Port to port 158 [mm]

  • Variable port to port dimension models (or zoom)

Using a moveable, flange old pumps can be quickly replaced without changing the pipe.
