Product Overview
The Grundfos MAGNA1 50 180 F N canned-rotor circulator pump integrates a permanent-magnet motor within a glandless structure for commercial building services. Eliminating mechanical shaft seals, internal liquid seals isolate stator windings. Connection interfaces feature DIN DN 50 ports for hydronic heating, air conditioning, and surface cooling loops.
Hydraulic performance delivers a maximum head of 18.0 meters and a maximum flow rate of 375.3 L/Min, matching 22.52 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 769 W and current draw of 3.4 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 19.5 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.
