The pump unit aims to force the circulation of the solar liquid flowing between the solar collector and the heat exchanger (often referred to as the tank). The solar liquid transmits heat from the solar collector to the exchanger.

The core of the pump unit is the circulating pump of specific parameters which enables the operation of the solar system as required. The pumps purchased fulfil the project design parameters and have energy class A, which will lower the costs of the system use as its power consumption will be lower.
