The slurry pump front casing, also known as the cover plate, is a core front pressure-bearing and flow-through component of AH, ZJ, ZGB, HH and  series horizontal slurry pumps. It matches the double-shell structure of slurry pumps and forms a complete sealed pump cavity with the rear casing, volute and front liner. The front casing adopts high-strength ductile iron and cast steel as the base material, equipped with replaceable wear-resistant liners of high-chrome alloy, rubber and polyurethane. It is suitable for conveying high-concentration and high-abrasive solid-liquid slurry in mining, coal washing, power plant desulfurization, river dredging and other industrial working conditions. As the key sealing and guiding part at the front end of the pump, it undertakes slurry inlet diversion, cavity sealing and fixing of protection plates and sealing components, isolating slurry erosion on external pump structures. Adopting precision casting and integral heat treatment, all products pass non-destructive testing and pressure inspection with no pores, sand holes or leakage. It is fully compatible with original factory standards, supports multi-angle installation and non-standard customization for replacement and new installation scenarios. (2) Product Advantages 1. Double-layer Structure with Dual Protection of Pressure Resistance and Wear Resistance The high-strength outer shell resists pressure and deformation, while the detachable wear-resistant inner liner bears direct slurry scouring and particle impact. The liner can be replaced independently after wear without changing the whole front casing, greatly reducing spare parts cost. 2. Multiple Material Options for Full Working Condition Adaptation Three mainstream wear-resistant materials are available: high-chrome alloy for high-abrasion working conditions with coarse and hard ore particles; natural rubber with excellent cavitation resistance and weak acid-base resistance, suitable for desulfurization slurry and fine tailings; polyurethane with light weight and no metal pollution, ideal for chemical and environmental protection medium transportation. 3. Optimized Flow Channel to Improve Operational Efficiency The front flow channel is optimized by fluid mechanics to ensure smooth inlet diversion, reduce slurry turbulence, eddy current and impact loss, lower pump operation resistance, avoid medium deposition and blockage, and maintain long-term efficient and stable operation of the pump. 4. Excellent Sealing Performance to Prevent Leakage Precision die-casting ensures a flat and smooth sealing surface. High-precision positioning holes achieve a perfect fit with liners and seals, effectively preventing slurry leakage and air inhalation, solving the problem of poor sealing of ordinary casings, and adapting to high-pressure and high-concentration slurry conveying. 5. Easy Installation and Maintenance, Lower Downtime Cost The standardized split structure allows independent disassembly and replacement without removing the overall pipeline. It simplifies maintenance operations, greatly shortens equipment downtime and improves continuous production efficiency. 6. Exquisite Craftsmanship and Longer Service Life Adopting precision investment casting and integral high-temperature heat treatment, the casing has a compact structure, high strength, strong impact resistance and crack resistance. All products are inspected by multiple non-destructive tests to ensure stable quality, with a service life far longer than ordinary cast iron front casings. 7. Full Model Spot Supply and Strong Versatility Covers all mainstream slurry pump series including AH, HH, ZJ, ZGB and , with fully interchangeable dimensions consistent with original factory standards. Sufficient spot goods support batch procurement and foreign trade supply, and non-standard specifications can be customized and delivered quickly.
