Product Overview

Circulating liquid through hydronic heating and cooling circuits, the Grundfos MAGNA1 50 120 F N canned-rotor pump replaces conventional shaft-sealed units with a glandless structure. An air-cooled control housing regulates pump operation. Pipe connections attach via DIN DN 50 ports across mixing manifolds and commercial thermal loops.

Hydraulic performance delivers a maximum head of 12.0 meters and a maximum flow rate of 330.8 L/Min, matching 19.85 m3/h. Powered by a permanent-magnet motor, the unit operates on a 240 V single-phase supply at 50/60 Hz, with power input P1 of 533 W and current draw of 2.37 Amps. Maximum system operating pressure is rated at 10 bar.

Housing construction features a stainless steel casing grade EN 1.4308 ASTM A351-CF8 enclosing a composite impeller. Internal components incorporate a carbon-fibre rotor can, stainless steel rotor cladding, and bearing plate, running on ceramic bearings. Net weight is 18.6 kg with a 280 mm port length, handling liquid temperatures -10 to 110 °C.

Control functionality offers three proportional pressure curves, three constant pressure curves, and three fixed speed steps selectable via a front panel push button. External monitoring and fault signaling are facilitated by a fault relay output and digital start/stop input. Ambient operating temperature spans 0 to 40 °C.

Features

  • Energy Efficiency Index (EEI): 0.20 meeting European Union energy performance standards.
  • Maximum rotational speed rating: 4188 rpm for continuous hydraulic balancing across system curves.
  • Physical shipping package volume and gross weight: 0.046 m3, 20.5 kg for logistics planning.
  • Standard regulatory compliance approvals: CE,VDE,EAC,MOROCCO,UKC for international building code conformity.
  • Drinking water suitability certification: WRAS, ACS for potable water circulation applications.
  • Integrated control functions: 3 proportional pressure, 3 constant pressure, and 3 fixed speed curves.
  • External signal interfaces: Fault relay output signal and digital remote start/stop control input.
  • Casing thermal insulation: Includes clip-on shell insulation covers for system heat retention.
