  • 【Durable Materials】:The impeller is made of high-performance chloroprene rubber composite material, which maintains flexibility and elasticity under temperature differences of -20 ° C to 120 °C, and has excellent corrosion resistance and deformation resistance. Even in harsh water quality or high temperature conditions, it can maintain strong pumping capacity. Non asbestos gaskets and stainless steel gaskets precisely control the clearance between the impeller and the pump body, effectively preventing medium leakage and ensuring optimal flow rate.
  • 【Restore Cooling & Protect Engine】: Replacing aging impellers and seals can quickly restore the efficiency of cooling water circulation, effectively prevent engine cylinder pulling due to overheating, and significantly extend engine life.
  • 【Complete Repair Kit】:This kit not only includes the core impeller, but also integrates related components with extremely high wear rates. Resolve all potential hazards at once, eliminating the hassle of searching for multiple part numbers and forming a complete cooling system repair loop.
