Applications

Applications

  • Heat transfer fluid pump
    Heat transfer fluid pump (HTF) pumps circulate thermal oil through the parabolic troughs to heat it up and pump it to the solar steam generator. The main characteristics of the HTF pumps are their high temperature and their double sealing system. Depending on the plant size, HTF pumps can be either double or end suction type.
