Product Overview
Featuring a cast iron housing grade EN 1561 EN-GJL-200, the Grundfos MAGNA3 65 150 F 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 DIN DN 65 connections.
Hydraulic performance delivers a maximum head of 15.0 meters and a maximum flow rate of 534.3 L/Min, matching 32.06 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 1377 W and current draw of 6.18 Amps. Maximum system operating pressure is rated at 10 bar.
Housing construction features a cast iron casing grade EN 1561 EN-GJL-200 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 22.7 kg with a 340 mm port length, handling liquid temperatures -10 to 110 °C.
Control features include AUTOADAPT and FLOWADAPT operating modes with integrated differential pressure and temperature sensors. Wireless communication connects via Bluetooth to Grundfos GO Remote software for diagnostics. External interfaces provide two digital inputs, two signal relays, and a 0-10V analog input.
