Medium UPM - EU range
This data booklet applies to the Grundfos Medium UPM pump range.
Applications
In a modern heating, cooling and domestic hot water
supply system there are different circuits in which
Medium UPM pumps in different versions can be
placed. A differentiation must be made between the
heating (or cooling) production and the distribution.
On the production side there are some applications
where pumps are used in primary or internal circuits
e.g. for geothermal or solar thermal brine circuits.
The distribution side is often split into two circuits - a
primary and a secondary circuit - in order to keep the
flow and temperature independent from each other. A
heat exchanger, a hydraulic separator or a buffer tank
can be used for this separation.
For some heating generators (e.g. condensing boilers,
heat pumps or district heating) it is important to keep
the return temperature as low as possible. Therefore it
is necessary to keep the right balance between flow in
primary and secondary circuits. Without separator, the
primary pump creates a differential pressure in the
secondary circuits. A generator effect can happen in
the secondary pump, from which Medium UPM pumps
are protected.
The primary pump is mostly integrated into the heating
appliance and controlled via a control signal (e.g.
PWM or BUS) to ensure the optimum operation of the
boiler, for instance.
