ZJR Type Centrifugal Slurry Pump

The ZJR pump (where "R" in the model number indicates a rubber liner) is a heavy-duty centrifugal pump with a double pump casing (vertically split type) structure. Its key feature is that the pump body and pump cover are equipped with replaceable rubber liners, and the impeller can also be made of rubber. It is particularly suitable for transporting slurries with certain corrosiveness or those requiring reduced wear and noise. . This series of pumps has a wide range of performance capabilities, with flow rates ranging from 12.6 m³/h to 5400 m³/h, a lift range of 5 - 68 meters, and outlet diameters of 25 - 450 mm. . The outlet of the pump can be rotated at intervals of 45° to be installed in eight different positions, meeting the requirements of various pipeline layouts.

Rubber inner lining for wear resistance and corrosion prevention: The flow components (such as the inner lining of the pump body, the impeller, etc.) are made of wear-resistant rubber (such as neoprene, polyurethane, etc.), which have excellent anti-wear and corrosion resistance. They are particularly suitable for transporting acidic or alkaline slurries or media that are corrosive to metals. At the same time, they can effectively reduce operating noise. .
High efficiency and energy conservation, along with wide performance range: Adopting an optimized hydraulic model design, it reduces vortex and impact losses, resulting in high efficiency. It has a wide performance range and excellent cavitation performance. It can meet long-distance transportation requirements by being connected in multiple stages in series. .
Reliable structure and easy maintenance: The pump body is of a vertical double-shell structure with an inner rubber lining. The rubber lining can be used until it wears through before being replaced, significantly extending the maintenance period and reducing operating costs. . The bearing assembly adopts a cylindrical structure, which is convenient for adjusting the gap between the impeller and facilitating overall disassembly during maintenance. .
Sealing and transmission methods are flexible: The shaft seal offers various forms such as packing seal, auxiliary impeller power seal, and mechanical seal, to meet different working conditions and sealing requirements. . The transmission methods include direct connection (DC), V-type belt (CL, CV, CR, ZL, ZV, ZR), gear reduction box, and hydraulic coupling, among others. .
Smooth operation and long service life: The design ensures the rigidity of the shaft, resulting in low vibration during operation, low noise, and low bearing temperature rise, with a long service life.

The ZJR type slurry pump is particularly suitable for the following industrial fields that have requirements for both corrosion and wear:
1. Chemical and wet metallurgy
Scenario: Phosphate production, titanium dioxide production, wet smelting of non-ferrous metals, etc.
Application: Transporting corrosive slurry containing acidic or alkaline components, such as phosphoric acid slurry, sulfate slurry, leaching solution, etc.
2. Mining and mineral processing
Scenario: Metal ore processing plants, especially those handling sulfide ores or using acidic reagents.
Application: Transporting concentrate, tailings slurry, or providing feedstock for hydrocyclones.
3. Electric power industry
Scenario: Flue gas desulfurization (FGD) systems in coal-fired power plants.
Application: Transporting weakly corrosive limestone slurry or gypsum slurry.
4. Coal washing and environmental protection
Scenario: Coal washing plants, industrial wastewater and municipal sewage treatment.
Application: Transporting coal slurry water, heavy medium suspension, or treating industrial sludge containing corrosive chemical substances.

1.Exquisite craftsmanship, high-standard product design
Long service life, easy operation, easy maintenance
Each production stage is strictly controlled to ensure that the products delivered to customers 100% meet national standards, and supply customers with higher-quality high-quality water pumps.

2.The pump body is made of customized cast iron/stainless steel materials. The impeller is made of wear-resistant and corrosion-resistant alloys and other materials. The hydraulic model design has been optimized, resulting in a more accurate curve for head and flow rate that better meets the actual usage requirements. The pump body material and control system can be customized according to the customer's medium characteristics (such as sand content, acid and alkali content), installation space, and operating duration, etc.
