Solar pump stations are used on the primary circuit of solar heating systems to control the temperature of the hot water storage. The pump inside the units is activated by the signal from the differential temperature controller. The units contain the functional and safety devices for an optimal circuit control, and are available with flow and return connection and with return connection only.
Solar Pump Station Features
- Ball valves in flow and return in combination with check valves to prevent gravity and thermo circulation
- Unit for flushing, filling and emptying the system
- Air vent for manual bleeding of the solar thermal system
- Flow meter for displaying and setting the flow rate
- Thermometer in flow and return for displaying both temperatures
- Pressure gauge for displaying the system pressure
- Safety relief valve to prevent overpressure
- Three-speed solar pump for wide range of flow rates
