Product Overview
Featuring a stainless steel housing grade EN 1.4308 ASTM A351-CF8, the Grundfos MAGNA1 25 120 N canned-rotor circulator pump provides glandless circulation for hydronic loops and HVAC networks. Internal electronics eliminate shaft seals through a canned-rotor configuration. Primary duties encompass mixing circuits, surface heating, air conditioning, and chiller loops using G 1 1/2 inch connections.
Hydraulic performance delivers a maximum head of 12.0 meters and a maximum flow rate of 95.8 L/Min, matching 5.745 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 188 W and current draw of 1.51 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 4.95 kg with a 180 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.
Features
- Energy Efficiency Index (EEI): 0.20 meeting European Union energy performance standards.
