Fluid End Pump Frames Stuffing Box Mechanical Seal Wear Pad of Centrifugal Pump Parts. Concentric Casing Design: Equal wall distance from impeller eliminates eddy currents and cavitation. Open Impeller Structure: Eliminates backflow and reduces wear by mixing fluid with returned liquid. Heavy Load Shaft Design: Large diameter shaft minimizes bending under heavy loads to prolong life. Replaceable Shaft Sleeve: Worn sleeves can be replaced without removing the shaft from the pump. Integrated Gland Design: Sealing and stuffing box functions integrated into a replaceable whole. Thick Mechanical Seal: Over 10 driving plates, 25-50% thicker than market standard for reduced stress. High-Quality Seal Materials: 316 stainless steel, fluorinated rubber, and tungsten carbide end faces. CE, RoHS, ISO Certified: Product meets CE, RoHS, and ISO 9001:2008 international standards.
