Grundfos UPS/D Light Commercial Single & Twin Head Circulators

The Grundfos range of light commercial circulators is used to circulate liquids in hot water and heating systems. The single and twin head variable speed pumps are suitable for installing into light commercial or domestic settings. In order to comply with the latest European legislation, Grundfos has replaced the UPS-D range of circulators with the MAGNA1 range. There is no need to make any changes to the existing pipe work to accommodate these new pumps, as it is simply a straight replacement. The pumps are ‘A’ rated and meet EuP regulations, which have reduced the amount of energy that these types of pumps use.

The MAGNA1 pumps are produced from cast iron and can be used in systems with variable flows. They are also suitable for systems that have hot water priority. The pump will receive a signal that tells it to function based on the maximum curve. This is the type of system that is found in applications such as solar heating. The circulator pumps have three different control modes: proportional pressure, constant pressure and fixed speed.

These circulator pumps are quick and simple to install. Once in operation it is easy to change the setting of the pump. There are nine clear indicator lights to display the setting that has been selected. They are suitable for use with liquid temperatures of between -10C and 110C. The pumps require hardly any maintenance and are extremely durable. They are manufactured to last a considerable length of time and offer a low cost ratio over the life of the system.
