Grundfos MAGNA3 32-80N (180) Variable Speed Single Head Circulator 240V - 97924343

The MAGNA3 is a single-phase pump with no maintenance requirements suitable for hot water service circulation with extremely low Life Cycle Cost.

The pump is characterised by the following:

  • controller integrated in the control box
  • control panel with TFT display on the control box
  • control box prepared for optional CIM modules
  • built-in differential-pressure and temperature sensor
  • cast-iron pump housing (depending on model)
  • carbon-fibre-reinforced composite rotor can
  • stainless-steel bearing plate and rotor cladding
  • aluminium alloy stator housing
  • air-cooled power electronics

Setting the MAGNA3 is simple – just install the pump and leave it on the AUTOADAPT setting, the pump will then analyse the heating system demands and find the optimum setting. It will then continuously adjust its operation to deal with changing system demands.

Characteristic features:

  • FLOWADAPT and FLOWLIMIT (more than a pump function as it reduces the need for pump throttling valves).
  • Proportional-pressure control.
  • Constant-pressure control.
  • Constant-temperature control.
  • Constant-curve duty.
  • Max. or min. curve duty.
  • Automatic Night Setback.
  • No external motor protection required.
  • Insulating shells supplied with single-head pumps for heating systems.
  • Large temperature range where the liquid temperature and the ambient temperature are independent of each other.

The MAGNA3 enables communication via the following:

  • wireless Grundfos GO Remote
  • fieldbus communication via CIM modules
  • digital inputs
  • relay outputs
  • analog input (more than a pump function as heat energy meter)
