structure and performance
The shielding sleeve is embedded inside the stator to isolate the rotor cavity and stator cavity, ensuring that the pump is completely leak free. Hastelloy stator shielding sleeve is made of special technology, with high precision, good quality, no welding defects, high magnetic permeability, and strong corrosion resistance. The sliding bearing material is made of crystalline silicon carbide (SSICSIC30), which has high strength, good wear resistance, and strong corrosion resistance. Its service life is more than 10 times that of graphite bearings. The shielding motor is a three-phase squirrel cage induction motor with high efficiency, protection level IP55, and explosion-proof level dellCT3-T5. This series of pumps has a simple and compact structure, easy installation and maintenance, automatic hydraulic balance of axial force, low noise, safe and reliable, and low total operating costs.
Scope of Application
1. Chemical industry
Used for transporting various chemical liquids such as acids, bases, solvents, etc. Its corrosion resistance and leak free characteristics make it particularly suitable for handling highly corrosive media.
2. Oil and gas industry
Used for transporting crude oil, natural gas, and related liquids. Its high head and high pressure characteristics enable it to adapt to complex transportation conditions.
3. Pharmaceutical industry
Used for transporting drugs, solvents, and medicinal solutions. Its low noise and leak free characteristics make it an ideal choice in the pharmaceutical process.
4. Electronic and semiconductor manufacturing
Used for transporting liquids with high purity and cleanliness, such as ultrapure water, deionized water, etc. Its low noise and leak free characteristics ensure a clean and stable production environment.
5. Nuclear power industry
Used for transporting nuclear grade liquids such as coolant, reactor cooling water, etc. Its high temperature, high pressure, and high head characteristics make it an important component of nuclear power plants.
6. Metallurgical industry
Used for transporting high-temperature molten metals, slag, etc. Its high temperature and high pressure resistance characteristics enable it to adapt to extreme working conditions.
7. Urban water supply and drainage and fire protection system
Used for boosting and transporting water, as well as for high-pressure water transportation in fire protection systems, to ensure stable water supply and pressure.
8. Heating, Ventilation, Refrigeration, and Landscape Sprinkler Irrigation
Used for transporting refrigerant and cooling water to ensure the normal operation of the air conditioning system. In garden sprinkler irrigation, it is used to transport high-pressure water for sprinkler irrigation.
9. Other fields
Shielded multi-stage pumps are also widely used in agricultural irrigation, food processing, environmental protection treatment and other fields, for transporting various liquid media.
