The ZJ series slurry pumps are single-stage, single-suction, horizontally cantilevered centrifugal pumps with an axial suction. They adopt advanced solid-liquid two-phase flow theory and are designed based on the principle of minimal loss. The geometric shape of the flow-through components conforms to the flow state of the medium, reducing local and along-path hydraulic losses such as eddy currents and collisions. This not only reduces the wear of the flow-through components but also improves hydraulic efficiency and lowers operating noise and vibration.
The flow-through components of this series of pumps are made of high-hardness alloy cast iron, which has high wear resistance, corrosion resistance, and impact resistance, thus greatly extending their service life. At the same time, the pump body adopts an inner-outer double-layer metal structure, and the pump casing is of a vertically split type. The water outlet can be rotated to eight different positions at 45° intervals, greatly increasing the flexibility of installation and use. The double-casing structure facilitates the replacement of flow-through components. According to pressure requirements, the outer pump casing is made of ductile iron or gray cast iron, and the inner pump casing is made of high-chromium wear-resistant white cast iron or cast steel, effectively extending the maintenance cycle and reducing operating costs.
The bearing assembly of the ZJ series slurry pumps adopts a cylindrical structure, which is convenient for adjusting the gap between the impeller and the front guard plate. It can be removed as a whole during maintenance, and the bearings are lubricated with grease, making maintenance simple. There are various types of shaft seals, including packing seal, auxiliary impeller seal, and mechanical seal. The appropriate sealing method can be selected according to different working conditions to ensure the tightness of the pump and reduce the risk of leakage. The transmission methods are also abundant, including V-belt drive, elastic coupling drive, gear reducer drive, hydraulic coupling drive, frequency conversion drive device, thyristor speed regulation, etc. Among them, the V-belt drive includes CL, CV, CR, ZL, ZV, ZR drives, which can meet various power transmission needs.
The ZJ series slurry pumps have a wide performance range, good cavitation performance, and high efficiency. They can adopt multi-stage series technology to meet long-distance conveying requirements. The maximum weight concentration of the slurry they can handle is: 45% for ash slurry, 60% for mineral slurry, and the medium temperature is ≤60°C. The product range is complete. Horizontal pumps are divided into various specifications according to the outlet diameter, including 350mm, 300mm, 250mm, 200mm, 150mm, 100mm, 80mm, 65mm, 50mm, 40mm, etc. For each specification of pump, different impeller diameters are available according to head requirements, which can meet various harsh conveying conditions.
The ZJ series slurry pumps are widely used in industrial sectors such as electric power, metallurgy, coal, building materials, and chemical industry. In the electric power industry, they can be used for ash and slag removal in power plants; in the metallurgical industry, for processing concentrates and tailings in mineral processing plants; in the coal industry, for conveying coal slime and dense medium coal preparation; in the chemical industry, for conveying abrasive or corrosive slurries containing solid particles, etc.
With its remarkable features such as high efficiency and energy saving, reliable operation, long service life, and convenient maintenance, as well as wide applicability, the ZJ series slurry pumps play an important role in the field of industrial slurry conveying. Choosing the ZJ series slurry pumps means choosing an efficient, stable, and reliable industrial conveying solution.
