Product Explosion Diagram
1. The water pump structure is shielded.
2. The front bearing seat is in contact with the medium, and the front insulating pad is used to insulate the front bearing seat and the casing;
3. To meet the insulation requirements of the rear bearing seat, a new structure is designed to isolate the rubber package of the rear bearing seat from the casing to meet the insulation requirements of the medium and the casing. The rear bearing seat is a separate component, distinct from the casing. The rear end face fixes the controller to dissipate heat for the controller, reduce temperature rise, and increase the service life of the controller. The front end is in contact with the circulating medium to take away the heat from the controller.
4. The motor shaft is a hollow structure. The medium enters the shielding sleeve through the front bearing seat in the high-pressure area of the volute, and enters the bottom of the motor shaft through the cross groove of the rear bearing seat after reaching the rear bearing seat, and returns to the water inlet of the water pump through the center hole of the motor shaft, forming a small heat dissipation circulation system.

Products Description
product key Feature
1. High efficiency and energy saving: It has high hydraulic efficiency and mechanical efficiency, which makes its energy consumption low during operation and meets the national requirements for energy conservation and emission reduction.
2. Smooth operation: The impeller and the motor rotor are coaxial, which makes the whole equipment run smoothly, with small vibration and low noise.
3. Easy maintenance: The special design makes its maintenance simple and convenient, reducing the maintenance cost and downtime of the equipment
4. Safe use: The motor is in direct contact with the liquid, and no additional mechanical seal is required, which effectively avoids the risk of leakage and is safe and reliable to use
