The casing has been upgraded to PPS+GF material, providing strongcompression, improving fatigue and stress resistance. lts sandblastedsurface enhances smoothness and corrosionresistance, ensuring highstrength, temperature resistance, chemical durability, and betterdimensional stability.

The water pump impeller is made of PPS+GF material, which has betterdynamic balance performance, more stable rotation, will not deflect and isnot easy to deform or fall off.

The moving ring of the pump head water seal is made of high-quality siliconcarbide and graphite materials, which have high wear resistance, low noiseand good air tightness: the static ring sealing ring is made of hydrogenatecbutadiene rubber. which can prevent the coolant from being contaminatecto the greatest extent .

The balls and rollers in the water pump bearinas are made of Cr15 materialThe unique one-ball-one-column design ensures uniform force and stablerotation, achieves optimal load distributionand further improves productperformance. Used in conjunction with precision mechanical seals, theservice life can be maximized.
