YQSH series submersible seawater three-phase asynchronous motor【Stainless steel submersible motor】, is a new product developed based on the introduction of technology from the German company Ritz. This product is a wet filled water seal structure, mainly used for driving submersible pumps to extract seawater from offshore platforms, and can also be used in other water quality with high chloride ions. The important components of the electric motor, such as the guide bearing and thrust bearing, have adopted new structures and materials, and a series of special designs have been adopted in sealing and anti-corrosion. They have the advantages of simple structure, reliable operation, long service life, easy maintenance, and high power performance indicators.

Conditions of Use
a. The electric motor should be completely submerged in seawater, with a depth of no more than 70m and a minimum distance of 5m from the seabed.
b. The electric motor operates continuously.
c. The seawater temperature shall not exceed 30 ℃.
d. The motor should be used vertically, and a water absorbing cover should be added during use to ensure that the flow velocity of water passing through the surface of the motor is greater than 0.5m/s
e. The electric motor must be filled with clean water or other water solutions prepared according to the prescribed ratio.

1. Scientific design, high single-stage lift, especially suitable for high lift needs, smooth operation with low noise.
2. The use of high-quality precision cast stainless steel as raw material and the adoption of scientific formula casting ensure the compactness of the molecular structure of the castings.
3. The precision machining of CNC lathes ensures the parallelism and perpendicularity of components, thus ensuring the concentricity of the pump body height and extending its service life.
4. Strict inspection, meticulous assembly, and full load performance testing are carried out in the factory to ensure users' peace of mind during use.
5. The bearing shell adopts an improved rubber bearing shell (confidential formula), which has twice the service life of ordinary bearing shells.
6. Pump shafts come in various materials such as stainless steel 431, stainless steel 631, Monel, etc. to suit different usage scenarios.
7. The impeller is made of stainless steel 304, 316, 316L, tin bronze, aluminum bronze, etc.
8. Some series of products draw on the technology of Ritz in Germany, increasing the circumference to fully meet the needs of high head submersible pumps.
