- 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.

- Variable port to port dimension models (or zoom)
Using a moveable, flange old pumps can be quickly replaced without changing the pipe.
