High Pressure Slurry Pump Overview
High pressure slurry pumps are pumps specially designed to handle slurries containing solid particles. They can provide extremely high outlet pressure and pump head so that slurry, coal slag, mud, etc. can be pumped to a longer distance.
The Kingda high-pressure slurry pump features a robust housing that can withstand higher pressures, and optional wear-resistant materials reduce erosion from slurry, maximizing the service life of the high-pressure slurry pump.
High pressure slurry pumps play an indispensable role in many industries, such as mining, dredging, tunnel, chemical, power plants, etc., which need to provide a high-pressure pumping environment to cope with the challenges of long-distance, high-pressure, and high-lift pumping.
High Pressure vs. High Head: What Is the Difference?
| Comparison | High Head | High Pressure |
|---|---|---|
| Definition |
It represents the energy transferred from the pump to the slurry, indicating the height difference the pump can pump the slurry to after overcoming pipeline resistance. It is usually expressed in meters (m) or feet (ft). |
This represents the force per unit area exerted by the slurry on pipelines and pumps, usually expressed in bar, kPa, MPa, or psi. |
| Influence of Slurry Density |
The pump head of the same centrifugal pump is mainly determined by the rotational speed and the impeller, and usually does not change with the density of the medium. |
At the same head, the greater the density of the slurry, the greater the pressure generated. |
Note: The final pump selection needs to consider multiple factors such as slurry density, solid concentration, viscosity, particle size, pipeline friction, NPSH, etc.
Explore how we successfully removed high-solids slurry from a 90-meter deep subway tunnel. In this video, Kingda provided a complete tunnel fluid delivery solution for the urban subway project.
In this project, booster pump station solved the problem of fluid delivery in a tunnel nearly 100 meters underground. Through a series of equipment and multi-stage high pressure slurry pumps in the booster pump station, ultra-long distance and ultra-high pressure fluid delivery were finally achieved.

High Pressure Slurry Pump Features
Pressure-resistant pump casing
The unique pressure-resistant casing design of the SGHP high pressure slurry pump ensures that it can easily cope with the impact of high-speed fluid on the pump under extremely high pressure and maintain the stability of the entire conveying system, which greatly improves the efficiency of the project.
Easy maintenance
The horizontal end-suction high-pressure slurry pump and modular platform and accessories can easily maintain or replace pump components, simplify manual maintenance operations, and enable it to enter the production process faster.
High efficiency
Our engineers combine the flow and pressure data of the pumping site, optimize the blade length of the impeller and increase the flow channel width, so that it can pass solid particles with larger diameters to ensure that there will be no blockage.
Always at optimal efficiency
Kingda SGHP high pressure slurry pump uses a more stable variable frequency motor and is equipped with a PLC control cabinet. In the event of a decrease in slurry volume or a sudden change in pressure, the motor speed is adjusted to keep the pump at its best efficiency, greatly reducing the wear on the pump.
Remote monitoring
When we install the pump, we will install the intelligent monitoring module in the pump. You can monitor the pressure, flow, and vibration speed of the pump through the Kingda remote monitoring system. When the data is abnormal, you will be warned by email or message to prevent greater economic losses.
Optional materials
Kingda provides many slurry pump lining materials to make your project more efficient. Ductile iron, wear-resistant alloy, stainless steel, rubber, ceramic, engineers will make the best choice according to the density and concentration of slurry to ensure that users are provided with efficient solutions.
KFSD sealing technology
The KFSD sealing system can withstand the erosion of high-temperature and high-pressure slurry. The equipped filter can effectively filter impurities in the water and reduce the risk of pump shaft leakage, greatly extending the service life.
Excellent performance
When we design fluid conveying solutions for customers, we will ensure that the slurry pump has sufficient redundancy. When encountering large pieces of solids or viscous slurry by chance, the extreme performance of Kingda high pressure slurry pump will break through all obstacles and without clogging.

The Kingda SGHP series high-pressure slurry pumps are designed specifically for high-pressure, long-distance conveying applications. Clamps on both sides of the pump body significantly increase the pump’s pressure-bearing capacity.
When used with a Kingda booster pump station, the SGHP pumps can be efficiently connected in series, significantly increasing conveying distances and maximizing fluid delivery efficiency.
High Pressure Slurry Pump Applications
Mining industry
High pressure slurry pumps are used in many links of the mining industry, from the transportation of coarse-grained slurry and flotation slurry to the long-distance transportation of coarse tailings.
Tunnel shield
In the process of tunneling, a large amount of highly abrasive mud and solid wastewater will be generated, which requires high-pressure and high-lift slurry pumps to remove the mud from the depths of the tunnel.
Dredging project
The slurry produced by dredging contains a large amount of gravel, debris, and silt. If a high pressure slurry pump is not used, it is difficult to discharge these slurries smoothly.
Metallurgical chemical industry
A lot of high-concentration slurries will be produced in metallurgical and chemical engineering, and there is a need to transport wastewater and waste residues over long distances. High pressure slurry pumps are undoubtedly the best choice.
Power plant
In the process of flue gas desulfurization, power plants need to transport a large amount of corrosive slurries such as limestone and gypsum. High pressure slurry pumps can smoothly transport these slurries with high solid content.
Booster Pump Stations for Long-Distance Transport
Kingda booster pump station plays an important role in the whole fluid transportation solution. Booster pump station is often used in ultra-long distance and high-load fluid transportation applications. It is often installed in the middle position to increase the pressure to meet the needs of long-distance and high-load transportation.
Kingda booster pump station can be connected to the project engineering control room to achieve remote control and reduce labor costs. By remotely controlling the booster pump station, the fluid transportation system can maintain stable pressure and flow to achieve maximum efficiency of fluid transportation.
Booster pump station is usually used in mining, tunnel shield, water treatment system. The additional pressure and flow added by the booster pump station ensure the smooth operation of the transportation system.

FAQ
When transporting slurry over extremely long distances or with significant height differences, the head and pressure of a single pump may not be sufficient to deliver the slurry to the designated location. In such cases, multiple pumps need to be connected in series to achieve the desired head and pressure.
Accurate slurry data is essential for selecting the right pump and preventing premature pump wear.
When choosing a slurry pump, factors such as slurry density, solids concentration, particle size, particle shape and hardness, and viscosity must be considered, as these factors influence the selection of materials, motor, and pump structure design.
Positive displacement pumps are suitable for conveying high-viscosity slurries or gas-liquid mixtures with high solids content. They also have low shear force and can be used to convey biological slurries, oils, etc. They are characterized by high efficiency and stability.
