Pump station for solar thermal systems flow and return connection PML pump Caleffi 255

Pump station for solar thermal systems, flow and return connection. PML pump Caleffi 255

The series of CALEFFI SOLAR products have been specifically designed for use in solar system circuits, where high temperatures can normally be reached and, depending on the type of system, there may be the presence of glycol. The materials with which the components are made and their performance must necessarily take into account these particular operating conditions.
