VSA Serisi

Description 
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.
