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.

Bearing Assembly

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 housing.

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.

Installation Types :

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.

DC Type: The output shaft of a motor is directly connected to the input shaft of a pump via a pump coupler. This type of connection is suitable for applications where the speed of the slurry pump is the same as that of the motor.

CV Type: The tailing handling slurry pump is driven by a belt connected to the crankshaft of the engine. This way of connection allows for saving space, easy installation, and fast adjustment of pumping speed. The motor is fixed to the motor support frame which is located on the bearing support above the slurry pump.

ZV Type: Another type of belt drive that allows easy adjustment of pumping speed. The motor is directly fixed to the bearing support. This way of installation is suitable for motors with larger horsepower than is possible with CV type of installation. Due to the installation of motor onto the bearing support, this method helps save installation space.

CR Type: This type of belt drive makes it easier to adjust pumping speed. The installation allows both the motor and slurry pump to be fixed to the ground. The motor is installed to the side of the pump. This installation method is suitable for large-power motors.

Wet End Parts Materials

Key wet-end components of XAH heavy-duty slurry pumps cover impeller, casing liner, frame plate liner and throat bush. These core spare parts are predominantly manufactured from high-chrome alloys and elastic rubber materials. A05 high-chrome alloy serves as the standard option for heavily abrasive yet mildly corrosive slurry thanks to superior abrasion resistance and balanced cost performance. When pumping strongly corrosive media, A49 alloy or rubber lining becomes the preferred alternative.
