Pump for circulation of fluid media in solar panel powered heating systems.
VSA wet rotor circulators can function perfectly also with high glycol concentrations (up to 60%).
Monobloc body composed of hydraulic section in cast iron and wet rotor motor. Special electrophoresis coating of the pump body to ensure resistance to glycol attack. Motor casing in diecast aluminium. Rotor in engineering polymer, motor shaft in hardened stainless steel held in graphite bearings lubricated by the pumping medium. Rotor protective jacket, stator jacket, and closing flange in stainless steel. Ceramic thrust ring, ethylene propylene seals and brass air breather plug. Two-pole asynchronous motor with squirrel cage rotor designed to run at three alternative speeds on the basis of the setting of a selector on the terminal board in order to adapt circulator operation to the characteristics of the system.
