Product Description Product DescriptionThe mud pump piston sealing ring is the core sealing component of the pump's hydraulic end, directly impacting the pump's operational efficiency and service life. Structure and Type1. Double-lip Sealing StructureDouble-lip design: The front end features a pointed front lip, with 1~2 pointed back lips in the middle. The outer edge of the back lip is elevated by 0.1~0.3mm compared to the front lip, and the junction is crafted with transitional rounded corners.Function: The front lip can accommodate large particles, while the back lip captures smaller particles and stores them in the angle, reducing friction resistance, enhancing wear resistance, and prolonging the life of the seal.2. Assembly Type and Integral Type StructureAssembly: Comprised of oil-resistant rubber lips (NBR or PU) and a nylon/tetrafluoroethylene/adhesive canvas root, secured by a pressing plate and clamp spring.Integral type: Utilizes polyurethane (PU) for integrated molding, with a hardness of 94 Shore A, providing superior wear resistance suitable for high-pressure environments.3. Multi-stage Sealing OptimizationThe design incorporates a nylon ring at the small cone end of the rubber leather bowl, and a polyurethane wear-resistant layer is applied to the outer side, forming a multi-stage seal to minimize erosion from mud infiltration.Detailed PhotosProduct ParametersKey performance parametersworking pressure Conventional type 19.6 to 35 MPa, HNBR type up to 75MPatemperature range-20~ + 150oC, high temperature type (HNBR) long-term tolerance of 150oCLife promotionThe new lip design improves the life span by 1.5 to 2 times, up to an average of 491 hoursPackaging & ShippingInstallation InstructionsApplication scenarios and maintenance key points1. Typical ScenariosOil Drilling: For high-pressure mud and sand-bearing particles, it is recommended to use PU or HNBR materials.Mining: In high-wear environments, adhesive canvas root or polyurethane composite materials are preferable.2. Maintenance StrategyRegular Inspection: Check for lip wear and root erosion every 200 hours and replace any abnormal parts promptly.Installation Specification: Ensure that the pressing plate and clamp spring are securely fastened to prevent root stripping due to mud infiltration.
