Description and specification:
A pump group is a device that ensures and regulates the circulation of solar liquid (a mixture of propylene glycol) between solar collectors and the tank. The group consists of a circulation pump and measuring and regulating devices. It can be used for both flat solar collectors and vacuum collectors. The advantage of the double pump group is that we have the ability to control the temperatures of the heating medium of the solar system on flow and return and the use of an air separator.
