Solar Pump Station SR962S

Double pipeline pump station SR962S
This solar pump station is a preinstalled and leak-tested group of fitting for transferring heat from the collector to the storage tank.
It contains important fittings and safety devices for the operation of the solar thermal system:
Ball valves in flow and return in combination with check valves to prevent gravity circulation.
Flow rate check for displaying the flow rate.
Manometer for displaying the system pressure.
Safety valve to prevent inadmissible overpressure.
Flushing and filling unit for flushing, filling and emptying the solar thermal system.
