HZJ Series Heavy Duty Double-case Slurry Pump

The HZJ Series are designed with high chrome alloy materials heavy duty slurry pump specifically designed to accommodate large quantities of abrasive and solids with particles at high flows.



Typically used in the mining, beneficiation, metallurgy industry units are designed to handle liquids chemical slurries, mud, lime , fly ash, gravel and mineral products. Applications range from transfer to filter press feed, and blasting.



The HZJ series of pumps are manufactured utilising oversized bearings of heavy duty design. Bearings can be grease or oil lubricated. Designs are available in a variety materials to accommodate all slurry types and can be directly motor driven or belt driven depending on application.



Structural Features:

- Single stage, single suction, double-case, horizontal centrifugal pump;



- Wet parts such as casing, impeller, liner plate in anti-abrasion high chrome cast iron alloy;



- The rotating assembly adopts standard bracket structure;



- Packing or mechanical seal; Sealing system cooled by pumped liquid or external cooling fluid. Expeller seal creates a hydrodynamic seal by creating an area of low pressure around the shaft. Expeller seals improve shaft sleeve lifetime and minimises water use. This combination ensures at low rpms and when the pump is stopped that the unit does not leak.



- The wet parts such as casing, impeller are thickened, the impeller channel is widened, generally designed as 3 or 4 vanes, to increase the flow area, reduce the flow rate of slurry in the channel, so as to improve the service life of the wet parts under severe abrasion conditions, suitable for the transportation of heavy abrasion slurry in various industries;
