Parts

Pump body

-cast iron: good pressure resistance (maximum working pressure: 6 bar)- inlet ring in the middle made of stainless steel

Impeller

-polypropylene (PP)-using metal component to connect the impeller with the ceramic rotor shaft (clamp connection)

Back plate

-stainless steel-ceramic bearing in the middle: high hardness, high temperature resistance

Rotor

-brass: alloy of copper and zink

Rotor can

-Stainless steel-Closes the part of the pump where water can be ( the water can’t reach the electrical part of the pump)

Stator

Terminal box

-nylon-capacitor (smoothing the output of the power supplies)

Power range system
