  • What is a Solar Pumping Station?

    A solar Pumping station is a module containing Heat transfer fluid circulation pump, solar differential controller, check valve, safety valve, filling valve, Tank temperature sensors and collector temperature sensor.

    Schematic

    This solar pump station is a pre-installed and leak-tested for transferring heat from the collector to the Water 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.
    • Air Vent for manual bleeding of the solar thermal system.
    • Electronic flow meter for displaying fluid flow rate.
    • Manometer for displaying system pressure.
    • Safety valve to prevent over pressure.
    • Flushing and filling unit for flushing, filling and emptying the solar thermal system.
    • Non-return valve: opening pressure 200mmH2O
