Casing and Impellers of Xbsy Mission Centrifugal Pump Parts. Concentric Casing Design: Equal distance from impeller eliminates eddy currents and cavitation, reducing radial bearing load. Open Impeller Structure: Eliminates backflow, reduces wear, and allows fluid mixing for extended service life. Durable Shaft Sleeve: Replaceable ceramic sleeve prevents shaft replacement; no need to remove shaft during maintenance. Heavy Load Capacity: Large diameter shaft minimizes bending under heavy loads, prolonging packing life. Thick Mechanical Seal: 25-50% thicker than market standard with over 10 driving plates for reduced stress. High-Grade Materials: 316 Stainless steel, fluorinated rubber, and tungsten carbide ensure superior performance. Integrated Sealing Box: Replaceable gland integrates sealing and stuffing box functions for easier maintenance. CE and ISO Certified: Product meets CE, RoHS, and ISO 9001:2008 standards for quality and safety.
