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.
Not sure which size? Send us your old pump's nameplate photo and we will confirm the right MAGNA.
