This document provides an exploded view and description of the main parts of a circulator pump. It lists 21 numbered parts including screws, o-rings, housing components, motors parts like the stator and rotor, bearings, impellers, inlet and outlet components made of materials like brass, stainless steel, nylon and cast iron. Key components are the pump body made of cast iron for pressure resistance, a polypropylene impeller, stainless steel back plate and rotor can, and ceramic bearings.

5. Parts

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

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

8. Back plate -stainless steel -ceramic bearing in the middle: high hardness, high temperature resistance

9. Rotor -brass: alloy of copper and zink

10. 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)

11. Stator

12. Terminal box -nylon -capacitor (smoothing the output of the power supplies)

13. Power range system
