Slurry pumps are equipment for conveying slurry containing solid particles, and are mainly used in mining, power plants, metallurgy, dredging, chemicals, building materials, petroleum and other industries.
To choose a suitable slurry pump to extend its service life, you can consider the following aspects:
Medium characteristics
- It is necessary to clarify the composition of the slurry, such as whether it contains corrosive chemicals or just solid particles such as mud and sand. If it is corrosive, you need to choose corrosion-resistant materials to make the slurry pump, such as high-chromium alloy.
- Pay attention to the concentration of the slurry. Slurry with high concentration will cause greater wear on the pump. Therefore, for high-concentration slurry, you should choose a pump with strong wear resistance, and its flow-through parts may need to use special wear-resistant materials.
- Consider the particle size of the slurry. Large particles are prone to blockage and excessive wear. You need to choose a slurry pump with a large pump body flow channel that can allow large particles to pass.
Flow and head
- Determine the flow rate according to the actual working conditions. The flow rate refers to the volume of liquid delivered by the pump per unit time. It is necessary to ensure that the rated flow of the selected pump can meet the delivery requirements in the working scenario.
- The head should be appropriate. The lift refers to the height to which the pump can lift water. It is necessary to consider the resistance of the entire conveying pipeline, vertical height and other factors, and select a slurry pump that can provide sufficient lift to avoid long-term overload operation of the pump.
Types of pumps
- Centrifugal slurry pumps are suitable for conveying media containing certain solid particles, with a wide range of flow and lift; while positive displacement slurry pumps are more suitable for conveying high-viscosity and high-concentration slurries. Choose the appropriate type according to the specific slurry characteristics and usage scenarios.
