MAGNA1 (D) Pumps and Spares

The MAGNA1 range of high energy efficiency circulators are designed to be used in refurbishment projects to replace a Grundfos UPS product or a small original Magna model. These medium and large circulators are suitable for commercial heating and cooling systems.

They can be used in a number of applications:
- heating systems
- air conditioning and cooling systems
- domestic water systems
- ground-source heat pump systems
- solar heating systems

These pumps circulate liquids in heating systems with variable flows where there's a need to optimise the settings of the pump duty point. This reduces energy consumption, lowering the cost. The electronically controlled motors are based on permanent magnet and stator technology. These high efficiency pumps already meet the Energy Efficiency Index level for 2015.

The range features 44 single and 39 twin pump models, with flange sizes between DN25 and DN100. Within the range there's a maximum head of 18m and a maximum flow of 70m3/h (140m3/h in twin head models). They can accommodate 6-16 bar system pressure and are suitable for liquids as low as -10oC. The liquid temperature of the system is now independent of the ambient temperature, allowing it to work with both heating and cooling systems.

MAGNA1 pumps have improved hydraulics and feature proportional and constant pressure control. There is a choice of nine pump settings and they operate with minimal noise levels. They are simple to install and offer a durable solution with limited maintenance. No external motor protection is required with this model and insulating shells are used for single head pumps within heating systems.
