The difference between centrifugal pumps and slurry pumps
Thread Content
What is the fundamental difference between these two types of pumps? Can they all handle media containing particles? What is the limit?
Most centrifugal pumps are primarily used to transport media with physical properties similar to water, that is, free of particles or containing only very small particles. Slurry pumps are specifically designed for transporting media containing mortar, sewage, and impurities.
In principle, a slurry pump is a type of centrifugal pump. Because the principles applied to them are all the same. The main working components of a centrifugal pump are the impeller and the casing; the impeller, which is located within the casing, is mounted on the shaft and connected to the prime mover to form a single unit. When the prime mover drives the impeller to rotate, the blades in the impeller force the fluid to rotate; that is, the blades do work on the fluid in the direction of its motion, thereby increasing the pressure potential energy and kinetic energy of the fluid. At the same time, under the influence of inertial forces, the fluid flows from the center toward the edges of the impeller, and exits the impeller at high speed to enter the discharge chamber, from where it is then expelled through the diffuser tube; this process is known as the water compression process. At the same time, as the fluid at the center of the impeller flows toward the edges, a low-pressure area is formed at the center of the impeller. When this pressure becomes low enough, under the influence of the pressure at the suction side, the fluid enters the impeller through the suction chamber; this process is known as the suction process. Due to the continuous rotation of the impeller, the fluid is continuously discharged and drawn in, enabling continuous operation. The basic working principle of slurry pumps is the same as well; they all operate based on centrifugal force. Therefore, a slurry pump is a type of centrifugal pump.
Slurry pumps fall under the category of centrifugal pumps. As the name suggests, they are centrifugal pumps capable of transporting slurry particles; they have an open impeller and are made from wear-resistant materials. The range of centrifugal pumps is too wide. . .
A slurry pump is a type of centrifugal pump; in addition to slurry pumps, certain specially designed centrifugal pumps can also handle media containing particles – each product needs to be analyzed on a case-by-case basis
The original poster doesn’t understand at all. Based on their working principle, they include centrifugal pumps, piston pumps, rotary vane pumps, etc. Classified by the working medium conditions, there are slurry pumps, sewage pumps, etc. For example: What is the difference between men and the elderly? You’re saying to let others answer you like that?

Centrifugal pumps are classified according to their specifications, while slurry pumps are classified based on the applications for which they are used; under the first classification method, all of them are considered centrifugal pumps. According to the second category, they are further divided into clean water pumps, sewage pumps, slurry pumps, etc., based on their purpose
The original poster should keep working hard to learn more! A centrifugal pump is considered in contrast to a positive displacement pump; a centrifugal pump uses the centrifugal force of the pump to continuously transport materials to the desired location, whereas a positive displacement pump relies on regular changes in the volume of its pumping chamber to transfer materials

Hehe, thank you all. I know that the working principles of slurry pumps and centrifugal pumps are the same, but in the industry, these two types of pumps are referred to differently; slurry pumps require a special design. What I want to know is what is the typical concentration of sewage or slurry, or the size of particles that a centrifugal pump can handle? In other words, under what circumstances is it necessary to use a slurry pump?
Ordinary centrifugal pumps handle multiphase flows, while slurry pumps are designed for two-phase flows and for solid-liquid mixed fluids; this design improves wear resistance, and the impeller design reduces the amount of machining required, facilitating processing of high-hardness materials
