Key spare parts include:

1. Screw and Rotor: As the core components of a pump, the screw and rotor are typically made from high-strength alloy materials, ensuring their wear resistance and long service life.

2. Sealing Components: Includes various seals, O-rings, and gaskets, used to prevent leaks and maintain the pump's sealing performance.

Bearings and shaft sleeves: Support and protect the rotating components of the pump, made of wear-resistant and high-temperature-resistant materials to ensure stable operation of the pump.

4. shaft sealing device: Different types of shaft seals, such as mechanical seals or packing seals, are used to protect the pump bearings and prevent medium leakage.

5. Drive Components and Couplings: Includes motor, reducer, and coupling accessories for the driving pump, ensuring normal operation of the pump.
