Slurry pump: a key conveying equipment in industrial production

I. Definition and Basic Function

A slurry pump is a mechanical device used for pumping liquids containing suspended solid particles. It increases the pressure of a liquid - solid particle mixture (slurry) to create flow. Operating specifications include maximum discharge flow and maximum discharge pressure, horsepower and brake horsepower, revolutions per minute (RPM) of the motor / pump rotating assembly, and media temperature.

II. Types of Slurry Pumps

Centrifugal Slurry Pumps

These are commonly used in slurry transport systems. The development of centrifugal pumps to handle high pressures and slurries with increased density and viscosity has broadened their range of application. They can be used for various industrial processes.

Positive Displacement (PD) Pumps

Also suitable for slurry transport systems, they work by trapping a fixed amount of slurry and then forcing it into the discharge pipe.

Submersible Slurry Pumps

Ideal for underwater applications, featuring advanced sealing and wear - resistant materials. They are designed to operate while submerged in the slurry, which is useful in applications such as in pits or sumps where the slurry is collected.

III. Applications in Industrial Production

Mining Industry

In the coal mining industry, slurry pumps are used to convey coal slurry over long distances. These conveying systems usually need to overcome high lift and long distance. Slurry pumps ensure the smooth conveying of coal slurry with their strong lift capacity and continuous and stable working performance. They are also used in tailings treatment.

Power Plants

Slurry pumps handle challenging materials that would clog or damage conventional pumps from the depths of mines to the heart of power plants. They can deal with slurries that may be corrosive or abrasive, which are common in power plant processes such as handling ash slurries.

IV. Factors Affecting Slurry Pump Performance

Particle Concentration and Flow Rate

The Euler - Euler method was used to examine how well slurry pumps performed when subjected to varying particle concentrations and low flow rates. The outcome demonstrated that the internal flow field was unstable and local wear was severe when the slurry pump was operating under part - load flow conditions.

Abrasion Resistance

Since they handle slurries with solid particles, the components of slurry pumps need to be robust and have good abrasion resistance to maintain consistent performance even in harsh conditions.

V. Manufacturers and Product Offerings

Metso Outotec

Their slurry pumps have a long history that leads to today’s modern slurry pump product line. Several companies and product lines have been combined over the years. Modern research and development techniques are now used to develop the next generation of slurry pumps.

DAE Pumps

Offers a comprehensive range of slurry pumps to meet diverse industrial requirements. Their product lineup includes slurry pumps engineered for durability and efficiency in handling abrasive and high - density slurries, as well as submersible slurry pumps.
