Applications In a modern heating, cooling and domestic hot water supply system there are different circuits in which UPM3 circulator 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 circulator 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....

Gas or oil-fired space and combination heaters Most of the installed systems for space and water heating in building services are still using fossil fuels such as natural gas or mineral oil, although the use of gas and liquid fuels out of biomass is increasing. Heaters with higher water content, such as floorstanding boilers, are heated independent of the actual flow. Heaters as wall-mounted boilers are only fired when there is a minimum flow through the primary heat exchanger. In a combi-boiler, the circulator pump supplies both the heating system and the hot water supply. More and more of these...

Micro/Mini combined heat and power cogeneration Cogeneration of heat and power (CHP) can be divided into combustion engines, stirling engines and fuel cells. Dosing and circulator pumps with customised specification are often installed inside the fuel cell process unit. Used secondary circulators are not that different from boiler applications. However, vibrations, liquid temperature and ambient temperature can be relatively high. Often a constant flow is required, therefore a buffer tank is an advantage. Thermal solar system Solar collectors convert sunlight into heat that can be used for heating...

This circulator pump range is designed for integration in boilers and other heating appliances with remote control of the speed, corresponding to low-voltage PWM signal input. One-pipe heating system Two-pipe heating system Underfloor heating system This circulator pump range with user interface is designed for several purposes: • The internal-controlled variant can be used in heating appliances as stand-alone or replacement pump, for example in heating kits. • The remote-controlled variant can be integrated in boilers and other heating appliances where the speed is changed, corresponding to...

4 UPM external control mode and signals 4. UPM external control mode and signals Control principles The UPM3 and UPM3 FLEX circulators are controlled via a digital low-voltage pulse-width modulation (PWM) signal which means that the speed of rotation depends on the input signal. UPM3 HYBRID circulators are controlled either internally or externally can be set to either internal or externally controlled. The speed changes as a function of the input profile. These communication signals are standardized in the VDMA Einheitsblatt 24244 "Wet runner circulating pumps Specification of PWM control signals"....
