Built on standard slurry pump design, the SiC ceramic slurry pump is a next-generation pumping solution. It fully utilizes silicon carbide ceramic’s outstanding properties — excellent wear resistance, corrosion resistance, impact resistance and high-temperature tolerance — combined with professional SiC ceramic technology to upgrade traditional slurry pumping performance.
This pump features a simple structure, strong part interchangeability, wide compatibility, high operating efficiency and low overall running costs.Under the same working conditions, the life of ceramic pump is more than 4-6 times that of traditional high chromium alloy slurry pump.
It is widely used for mining, mineral processing, metallurgy, power generation, coal washing, chemical processing and sand washing industries. With stable and reliable field performance, SiC ceramic slurry pumps have won wide recognition and positive feedback from global customers.
What Is Silicon Carbide (SiC)Material?
Silicon carbide (SiC) is a proven wear-resistant material. It features high hardness and stable molecular structure, with outstanding resistance to corrosion and high temperature. It is widely used in mining, metallurgy, power, chemical and other industries.Most slurry pumps at home and abroad work with highly corrosive and abrasive media under harsh conditions. Thus, wetted parts need strong anti-corrosion and anti-wear performance. Silicon carbide ceramic — including silicon nitride bonded sintered SiC ceramic and resin-bonded SiC composite ceramic — is your top pick.
SiC ceramic is the most widely used non-metallic industrial ceramic with superb high-temperature resistance. Its excellent structural performance relies on refined microstructures, so high-quality SiC powder production is the core to make premium SiC ceramic parts.
Silicon carbide (chemical formula: SiC) is a covalent compound. Both carbon and silicon have four valence bonds, and silicon carries partial metallic properties. Their network & bulky molecular structure delivers remarkable mechanical strength. That’s why SiC boasts great high-temperature strength, wear resistance, corrosion resistance, high thermal conductivity and excellent insulation.
Why Choosse Silicon Carbide (SiC) Ceramic Material?
Excellent chemical stability: Resists corrosion from nearly all inorganic acids, organic acids and alkalis, with great anti-oxidation performance.
Extraordinary wear resistance: 3 to 5 times more wear-resistant than high-chromium wear-resistant steel.
Outstanding corrosion tolerance: Compatible with most acids, alkalis and chemical agents, except hydrofluoric acid and hot concentrated alkali.
▲ Exceptional Wear Resistance of Silicon Carbide
Silicon carbide features a diamond-like tetrahedral crystal structure bonded mainly by covalent bonds. Its hardness ranks second only to diamond.
Extraordinary wear resistance: 3 to 5 times more wear-resistant than high-chromium wear-resistant steel.
▲Superior Impact Resistance of Silicon Carbide
Great impact resistance: Withstands impact from large granular materials and steel balls.
▲High Temperature Resistance of Silicon Carbide
Wide operating temperature range: Stable long-term service from -40℃ to 90℃, peak working temperature up to 110℃.
Our ceramic slurry pumps are built for easy maintenance, high efficiency and long life. Here’s how:
All flow-passing parts (pump body, impeller, liners) are made of wear-resistant, corrosion-resistant silicon carbide ceramic, ensuring long service life.
The axial adjustment structure lets you easily adjust the impeller gap, keeping the pump running at high efficiency at all times.
Back-pull design allows you to remove the impeller, shaft and seal without disconnecting the suction and discharge pipes, making maintenance fast and simple.
Large-diameter, short overhang pump shaft reduces deflection, protecting the seal and extending its life.
Thin-oil lubricated bearings are housed in a removable bearing box with rubber seals to keep out dirt and water.
A large tapered space between the impeller and pump cover prevents solids from entering the shaft seal, further extending seal life.
Rigid shaft design with roller and thrust bearings handles heavy radial loads, keeping the drive system running smoothly and reliably.

DISSCUSS YOUR APPLICATION
Shaft Seal Types
XAH series heavy-duty slurry pumps support three mainstream shaft sealing solutions: packing seal, expeller seal and mechanical seal. Users can select the most suitable sealing configuration based on on-site working conditions and personalized application requirements. The detailed structure and applicable specifications of each sealing type are displayed in the figure below.
Packing Seal
A packing seal works by filling elastic packing material into the pump’s stuffing box. As the packing gland compresses the material, it expands radially to fully seal the clearance between the shaft sleeve and stuffing box, achieving effective leakage prevention. This sealing structure allows a slight amount of dripping during operation and features excellent universal adaptability. Serving as the standard sealing configuration for Warman slurry pumps, it boasts mature technology, affordable costs and extremely convenient replacement and maintenance procedures. It is worth noting that packing seals require continuous shaft sealing water for normal operation, with the sealing water pressure maintained 0.035MPa higher than the pump outlet pressure.
Expeller Seal
The expeller sealing structure prevents slurry leakage by utilizing the centrifugal pressure generated by the impeller-driven expeller during operation. This sealing method requires no shaft sealing water, avoiding dilution of the conveyed slurry, which makes it ideal for water-scarce working environments and applications that demand undiluted slurry media. This seal is only applicable when the pump inlet pressure is no more than 10% of the outlet pressure; it cannot work properly beyond this range. Fitted with an oil cup, the expeller ring needs regular grease replenishment to ensure stable performance. Notably, the packing structure undertakes the sealing function when the pump is shut down. In addition to standard metal configurations, rubber-made expeller rings and complete expeller assemblies are also available for diverse working conditions.
Mechanical Seal
Mechanical seals are specially designed for strict no-leakage working scenarios and fluid conveying requirements. Though they feature a relatively higher cost, they deliver outstanding durability and simple replacement procedures, while requiring standardized and rigorous daily operational maintenance. Three mainstream types are available for different working conditions. The external flushing mechanical seal requires clean external flushing water with a constant pressure of 0.1MPa. The internal flushing mechanical seal also adopts clean flushing water, with the water pressure set 0.1MPa higher than the pump chamber pressure to achieve effective internal flushing. The non-flushing mechanical seal operates stably without any flushing water supply, meeting the demands of diverse special working conditions.
XAH series heavy-duty slurry pumps are equipped with robust cartridge-style bearing units that adopt grease lubrication for stable and long-term operation. Frames ranging from A, B, C, D, E, F to G are fitted with two opposed-mounted imperial single-row tapered roller bearings for balanced load bearing. In comparison, frame types including R, S, ST, T, TU and U feature a different configuration: one imperial double-row tapered roller bearing installed at the pump side, paired with two metric cylindrical roller bearings arranged at the drive side. The end cover adopts a labyrinth sealing structure with an integrated dust ring to block external dust and impurities. Precise axial clearance adjustment can be easily completed via the adjusting bolt installed between the pump frame and bearing .
Pump Frame
XAH heavy-duty slurry pumps feature an integral pump base designed to securely support the cartridge bearing and shaft set via clamping fasteners. Few penetrating bolts fasten the frame plate onto the main frame body. This compact, high-rigidity layout simplifies field disassembly and routine servicing. Every frame specification matches a rated maximum drive power plus the optimal flush water flow rate required for packing-type shaft seals.

XAH series heavy-duty slurry pumps rely on matched drive motors to supply power for slurry conveying tasks, with multiple flexible transmission options for different installation layouts. Common drive forms consist of direct-coupled DCZ, horizontally side-mounted CRZ, top vertical CV and inverted top-mounted ZVZ to satisfy varied site layout demands.
