Features
The absolute concentricity of the pump shaft and the excellent dynamic and static balance of the impeller ensure smooth operation without vibration. The hard alloy seals of different materials ensure that there is no leakage in the conveyance of different media. The structure is simple and reasonable. The key part adopts international first-class quality support. The trouble-free working time of the whole machine is greatly improved. Easy maintenance, easy replacement of seals and bearings. Series flow range 1.5 ~ 2000m3 / h, head range 5 ~ 125m
1. Stable operation: The absolute concentricity of the pump shaft has excellent dynamic and static balance, which ensures smooth operation and absolutely no vibration.
2. No water leakage: Carbide seals of different materials ensure that there is no leakage in the conveyance of different media.
3. Low noise: The water pump under two low-noise bearings runs smoothly, except for the weak sound of the motor, which is basically no noise.
4. Low failure rate: The structure is simple and reasonable, and the key parts are equipped with international first-class quality. The trouble-free working time of the whole machine is greatly improved.
5, easy maintenance: replacement of seals, bearings, simple and convenient.
6. More space-saving: The exit can be left, right, and up, which is convenient for pipe layout and installation, saving space.

Product Usage
