Single-Stage Mining Slurry Pump
Product Features
The single-stage mining slurry pump is a special centrifugal pump designed specifically for conveying abrasive slurries containing solid particles in the mining industry. It adopts a single-stage, single-suction, cantilevered horizontal structure, featuring strong wear resistance, high efficiency, compact structure, and reliable operation. This pump is a key piece of equipment in mining, mineral processing plants, metallurgy, and coal industries for conveying abrasive media such as slurry, tailings, and coal slime.
Single-stage pump features include simple structure, convenient maintenance, high efficiency, and good reliability. Its applications are wide-ranging, covering industrial boosting, urban water supply, water treatment, and agricultural irrigation. The single-stage pump converts mechanical energy into liquid kinetic energy through impeller rotation.
Simple and Compact Structure
The single-stage pump has a relatively simple structure, typically consisting of an impeller, pump casing, shaft, and bearings.
High efficiency
Utilizes centrifugal force to convert mechanical energy into liquid kinetic energy, resulting in high performance.
Wide range of applications
Highly adaptable to different flow rate and head requirements.
Convenient Maintenance
Some models, such as horizontal split-case pumps, do not require disassembly of pipelines and motors during maintenance, facilitating upkeep. Furthermore, some pumps are designed to allow replacement of the mechanical seal without disassembling the motor.
High operational reliability
Shaft seals (such as mechanical seals or packing seals) ensure stable pump operation; some double-suction pump models can achieve long-term leak-free operation.
Adaptable to different media
Pumps of different materials and models can be designed according to the characteristics of the transported media, such as corrosion-resistant chemical pumps and high-temperature resistant media pumps.

Material Description
The material selection for single-unit mining slurry pumps needs to comprehensively consider wear resistance, corrosion resistance, and economy:
High-chromium Alloy Materials
High-chromium wear-resistant alloys such as Cr27 and Cr30, with a hardness reaching HRC58-62, offer excellent wear resistance and are suitable for conveying media containing a large amount of solid particles and abrasive properties. High-chromium alloy cast iron typically contains more than 12% chromium (Cr). Chromium improves the as-cast structure of white cast iron, forming carbides and significantly enhancing the material's wear resistance. After heat treatment, its hardness can reach HRC 58-62, making it suitable for highly abrasive applications.
Stainless Steel Materials
304, 316, 316L, etc., offer good corrosion resistance and are suitable for conveying media containing corrosive substances. Duplex stainless steels such as A49 and A33 not only possess the wear resistance of high-chromium alloys but also exhibit good corrosion resistance and strong acid resistance, making them particularly suitable for pumps used in flue gas desulfurization systems.
Wear-resistant Rubber Materials
Non-metallic wear-resistant materials such as natural and synthetic rubber are primarily suitable for conveying fine-particle slurries without sharp edges. Their wear resistance is superior to some metallic materials, and they are especially suitable for conveying slurries with particle sizes less than 10mm.
Ductile Cast Iron Materials
QT500-7, etc., offer good strength and toughness, making them suitable for conveying media containing solid particles. Pump casings can be made of ordinary cast iron, cast steel, alloys, etc., allowing users to choose according to specific applications.
Company Introduction
CZME is a world-class manufacturer of high-performance pumping solutions, serving industries such as mining, construction, environmental protection, and water treatment. We specialize in producing slurry pumps, dredging pumps, desulfurization pumps, marine dredging pumps, and other industrial pumps for handling solid, highly abrasive, and corrosive slurries.
Application Scenarios
Single-unit mining slurry pumps are widely used in the following areas:
- Mining Industry: Used for slurry conveying, tailings conveying, and slag treatment in mineral processing plants. In the mineral processing flow, slurry pumps are required at every stage from ore crushing to concentrate production, including ball mill discharge, hydrocyclone feeding, flotation feeding, concentrate conveying, and tailings conveying. Approximately 80% of slurry pumps are used in mineral processing plants. Due to the harsh conditions in the initial ore processing stage, the service life of slurry pumps in this stage is generally short.
- Metallurgical Industry: Used for conveying blast furnace slag, furnace slag, and iron oxide scale in steel plants. Slurry pumps in the metallurgical industry need to handle high-concentration, highly corrosive slurries and potential particulate abrasion.
- Power Industry: Used in hydraulic ash removal, fly ash conveying, and flue gas desulfurization systems in thermal power plants. In flue gas desulfurization systems, slurry pumps need to convey media containing limestone or gypsum slurry, a condition characterized by not only abrasion but also strong corrosiveness.
- Coal Washing Industry: Used for conveying coal slurry and heavy media in coal washing plants, transporting coal slime and heavy media coal preparation. Due to different operating conditions, larger coal chunks and coal gangue are prone to clogging, placing high demands on the design of slurry pumps.
- Dredging and River Management: Used for dredging rivers, lakes, and seas, land reclamation, and sand mining operations. These pumps are often called "mud pumps" or "sand pumps," characterized by extremely wide flow channels that allow the passage of large pebbles or mud.
- Other Fields: It is also widely used in chemical, building materials, environmental protection, municipal engineering and other fields to transport slurries containing abrasive solid particles, and has become an indispensable key equipment in modern industry.
