Slurry Pump End Cover – Core Component for Sealing Protection and Precise Adaptation

Product Overview: Key Sealing and Protection Accessory for Slurry Pumps
This product is a dedicated end cover for medium and heavy-duty slurry pumps such as Jch-Tiktop 6/4-AH(R). Made from high-quality HT200 gray cast iron through integral casting, it serves as a core component for pump body sealing protection and part positioning. It precisely fits transmission components like the large-diameter DAM073M shaft and 45# steel shaft, and perfectly matches cartridge-type bearing housings and bearing assemblies. Its key functions include sealing the internal space of the pump body, fixing the axial position of bearings, and isolating external impurities. Through tempering treatment and precision machining, the HT200 material endows the end cover with excellent rigidity, sealing performance, and adaptability. It effectively cooperates with bearing assemblies to reduce vibration, block sand, gravel, and moisture in slurry media from invading, and provides comprehensive protection for core components such as pump shafts and bearings, ensuring the long-term stable operation of slurry pumps under heavy-load and impurity-rich working conditions.

Core Advantages: Empowered by HT200 Material for Harsh Slurry Conditions
1. Adaptable Material Performance with Stable Protection
HT200 gray cast iron has a Brinell hardness of HB180-250, featuring uniform and dense material, high rigidity, and excellent deformation resistance. It accurately matches the working pressure and load requirements of medium and heavy-duty slurry pumps, effectively withstanding internal pump pressure and external impact, and avoiding end cover deformation or seal failure caused by pressure fluctuations. Complementing the high-strength characteristics of 45# steel shafts, it maintains structural stability in high-concentration slurry transportation scenarios, providing solid support for the sealing system.

2. Optimized Structural Design for Enhanced Sealing Protection
Integrated seal groove design: Precisely fits seals such as O-rings and skeleton oil seals, forming a dual sealing barrier to effectively block slurry, dust, and moisture from invading the bearing cavity, preventing lubricant leakage and corrosion of internal components, and extending the service life of bearings and shafts;
Precision positioning and bolt hole design: Fully matches the mounting holes of bearing housings and pump frames, and is firmly fixed by bolts to ensure tight fitting between the end cover and pump body, reducing vibration gaps during operation and improving overall sealing performance;
Adaptation to short overhang design: The thickness and structure of the end cover are mechanically optimized to help reduce shaft deflection and minimize the impact of vibration on the sealing system, further enhancing sealing reliability.

3. Precision Machining for Excellent Fitting Accuracy
High-precision machining using CNC lathes and milling machines ensures key dimensional tolerances are controlled at IT7-IT8 level, with end face flatness error ≤0.02mm. The fitting clearance with 45# steel shafts and bearing assemblies is precisely controlled, avoiding vibration noise or seal failure caused by fitting deviations, ensuring smooth rotation of the shaft, and reducing wear between components to improve the operational smoothness and service life of the entire pump unit.

4. Strong Adaptability and Flexible Customization
HT200 gray cast iron has good machinability and can be customized with structural parameters such as bolt hole positions, seal groove sizes, and end cover thickness according to the assembly requirements of different slurry pump models, perfectly matching the assembly standards of various medium and heavy-duty slurry pumps. The surface can be treated with anti-rust painting, phosphating, etc., to further improve corrosion resistance, adapting to harsh working environments such as dusty and high-humidity conditions in mining and metallurgy industries.
