Grundfos MAGNA1 65-80F (340) Variable Speed Circulator 240V

Designed for circulating water in heating and domestic hot-water systems, the Grundfos MAGNA1 65-80F (340) is an A-rated, EuP-ready variable-speed circulator that runs on 240V. The MAGNA1 65 range has 340 mm port-to-port dimensions and 65 mm flanged connections; this unit is built in cast iron and is intended for applications such as heating systems, main pumps, mixing loops and heating and air-conditioning systems.

• Variable-speed control with selectable proportional, constant-pressure and fixed-speed curves for matching pump performance to system demand.
• Maximum flow up to 40 m3/hr and maximum head of 8 m, supporting a wide range of circulation requirements.
• Liquid temperature range suitable for water from -10 °C to 110 °C.
• 240V single-phase motor; listed full-load current range 0.26–2.11 A and motor power values shown in the product data.
• Low noise, maintenance-free design and compliance with EuP requirements to reduce life-cycle energy use.

Dimensions are approximately 340 mm (h) × 266 mm (w) × 386 mm (d) and the unit weighs about 23.8 kg. The pump is suitable for systems requiring hot-water priority via an external signal and includes indicator lights for pump setting selection.
