1. high precision: both the impeller and the guide impeller are made of precision casting.
2. Low noise: the noise value is less than 40dB during operation, which is safer and more environmentally friendly.
3. High efficiency: the floating impeller is adopted, which is extremely efficient, and the number of pump stages is correspondingly reduced.
4. Save space: Tonghui pump body is formed by precision casting, and the short design is one meter shorter than ordinary pump body on average.
5. No pollution: the pump body and motor are made of 304 stainless steel, which has strong corrosion resistance and no secondary pollution.
6.NEMA: All dimensions of submersible pump motor joints meet NEMA standards.
7. Various combinations: The water pump can be assembled flexibly according to different flow and lift.
8. The only pump sand control design in the world, pump outlet shaft seal and double sand control measures can limit the prevention of fine sand infiltration.
Patented technology, more reliable
The integrally formed patented impeller is balanced and corrected by a precise microcomputer balancer, and the impeller is concentric, which can effectively reduce the vibration generated when the pump is running, relatively improve the stability of the pump motor, avoid the wear of the motor bearing caused by vibration, and prolong the service life of the pump motor.
