How to choose
- Match the pipe size and the port-to-port length of the pump you are replacing.
- Pick a maximum head above your system's needed head; the pump's control will turn it down to suit.
- Cast iron or stainless steel (N) housing, to suit the system.
- Twin-head (D) where the building cannot lose circulation if one pump head fails.
- MAGNA3 for AUTOADAPT, heat energy monitoring or fieldbus BMS communication; MAGNA1 for nine-setting control with a fault relay and start/stop input.
