Slurry pumps are a type of pump product suitable for transporting liquids (water) with suspended solids, and they belong to the category of centrifugal pumps in terms of working principle. Slurry pumps are widely used in many industries, including mining, power plants, dredging, metallurgy, chemical engineering, building materials, and petroleum, especially in mineral processing and coal preparation plants.

Efficient operation is a major feature of slurry pumps, and one of the main factors affecting their efficient operation is the selection and design. In addition, the selection and design of slurry pumps also have a significant impact on their service life and are a key factor in determining whether the slurry pump can achieve efficient operation.
Slurry pumps have the characteristic of low loss; the flow components of the pump have a relatively long service life, which helps save production costs. Additionally, the entire industrial system operates relatively stably, so the operation of the slurry pump does not affect the entire industrial system, greatly facilitating smooth work progress.
A subtle advantage of slurry pump design is the fixed device for low-friction bearings on the rotor. While other manufacturers allow internal radial bearings to 'float' within the housing, slurry pumps keep the bearings in proper position. This feature, combined with a short cantilever impeller and large diameter shaft, creates an unusually rigid and deflection-resistant rotating component. Furthermore, fixing the short shaft length between the radial bearing and mechanical seal surface reduces the likelihood of thermal growth issues that could cause overpressure at the sealing surface. This is crucial for providing a mechanical environment that can offer long service life for mechanical seals. Therefore, selecting the correct type of bearing is very important for slurry pumps.
Features of submersible slurry pumps:
1. The entire unit of the submersible slurry pump has a dry motor structure below the pump. The motor uses mechanical seal protection to effectively prevent high-pressure water and impurities from entering the motor cavity.
2. In addition to the main impeller, submersible slurry pumps also have a stirring impeller that can stir up slag deposited on the bottom of the water into turbulence before pumping it out.
3. The impeller, stirring impeller, and other main flow components of submersible slurry pumps are made from highly wear-resistant materials that are wear-resistant, corrosion-resistant, and non-clogging, with strong sewage discharge capacity that can effectively pass larger solid particles. They are not limited by suction range, have high slag suction efficiency, and provide more thorough dredging.
4. No auxiliary vacuum pump is required, resulting in lower investment; there are no auxiliary stirring or spraying devices, making operation simpler.
5. The motor is submerged in water without needing to build complex ground protection and fixing devices, making management easier;
6. The stirring impeller of the submersible slurry pump directly contacts the sediment surface, with concentration controlled by submersion depth, making concentration control easier. The equipment operates directly underwater with no noise or vibration, keeping the site cleaner.
The above are some knowledge points about slurry pumps; I hope they can help everyone choose products that meet their needs.
