The Grundfos MAGNA3 will automatically analyse the heating system, find the optimum setting and then continuously adjust its operation to changes in demand. The result is optimum comfort and minimum energy consumption.

In addition, MAGNA3 pumps are extremely flexible and reliable, and have low noise levels, long life and no maintenance requirements. They are fitted with IR communication and can offer external control and monitoring via expansion modules.

UPS Large

Grundfos Large UPS is a canned rotor, centrifugal pump for circulating water in heating systems and smaller air-conditioner systems in commercial buildings. These pumps are based on glandless pump or canned rotor technology. The pumped liquid cools and lubricates the motor and rotating parts.
Large UPS circulators are typically used in commercial building like schools, hospitals and office buildings for circulating domestic hot water, heating water and air-conditioning fluid.

UPS pumps constitute a complete range of 3-speed circulator pumps, available both in 50 and 60 Hz.  The circulator pumps in cast iron pump housing version
are specifically designed for heating systems.

The pumps can be used in both open and closed systems. UPS pumps are of the canned-rotor type, i.e. pump and motor form an integral unit without a shaft seal and with only two gaskets for sealing. The bearings are lubricated by the pumped liquid.

The Grundfos SEV and SE1 pumps are designed for handling wastewater, process water and unscreened raw sewage in heavy-duty municipal, utility, and industrial applications.

These two technologically very advanced series of pumps are available with efficient single-channel or SuperVortex impellers allowing for free passage of solids up to 100 mm in size. This greatly reduces the risk of clogging, and ensures maximum up-time and low operating costs.
