The impeller and the sheath are lined with evergreen independent research and development of high wear-resistant rubber, ensure the pump can not be worn, in the same project, compared with other metal pump long life 2 times, reached the international top quality, the rubber lining wear index has reached 128%.

Because the wear resistant rubber is light and elastic, the starting energy consumption is small, and the running noise is reduced by more than 60%. 

Because of the small proportion of rubber, the impeller is especially lightweight, which makes the maximum lift and maximum flow of the pump increase by 10-20% than the other pumps, and the overall efficiency is increased by more than 30%.

The whole body is protected by abrasion resistant rubber, and the high abrasion resistant rubber over-current parts have low failure rate. Besides. The overflow parts are light, convenient to change and reduce the operation and maintenance costs.
