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 storage tank. It contains important fittings and safety devices for the operation of the solar thermal system:

  • Ball valves in supply and return lines in combination with check valves to prevent gravity circulation.
  • Flow meter for displaying the flow rate
  • Manometer for displaying the system pressure
  • Safety valve to prevent inadmissible over pressure
  • Flushing and filling unit (optional) for flushing, filling and emptying the solar thermal system.
