Product Introduction:
The AHK series of slurry pumps are single-stage, single-suction cantilever horizontal centrifugal pumps, suitable for transporting liquids containing suspended solid particles in industrial sectors such as metallurgy, mining, coal, electricity, and building materials. These liquids include highly hard, highly corrosive, and high-concentration slurries such as concentrate, tailings, ash slag, coal cinder, cement, soil, and placer minerals.
The AHKR rubber-lined pump is designed for special working conditions with fine particles without sharp edges. High-quality wear-resistant rubber is selected, which has good wear resistance, tear resistance, impact resistance, high elasticity, and chemical stability.
The typical working conditions are as follows: the concentration of the transported slurry is ≤60%, the temperature of the medium is ≤80°C, and the solid particles are 80 to 200 meshes.

Product Introduction:
The ZS series of slurry pumps adopt a horizontal, single-stage, single-suction, cantilever double-shell design. It is a specially upgraded product developed by the design team of Sanlian Pump Industry based on years of experience in centrifugal pump design. This pump features high efficiency, a reasonable structure, a spacious flow passage, strong flow capacity, high reliability, and convenient maintenance.

Product Features:
Aiming at complex pipeline structures, the pump's discharge port is designed to be rotatable. It can be rotated to 8 different installation positions at intervals of 45°.
In applications with long conveying pipelines, by adopting a series connection structure and coordinating with terminal speed regulation, the ZS series of slurry pumps can meet the requirements of most working conditions.
The sealing structure has been optimized. When the head of the pump H ≤ 0.5MPa, packing seal is adopted; when the head is within the range of 0.4MPa ≤ H ≤ 0.8MPa, a combined sealing method of auxiliary impeller plus packing seal can be selected. The packing is made of wear-resistant and corrosion-resistant carbon fiber materials, and the shaft sleeve is flushed and cooled by externally connected clean pressurized water, effectively preventing slurry particles from entering the shaft sleeve and packing, and significantly extending the service life of the packing seal.
