Gravel pumps are cantilever and centrifugal pumps. It adopts a single pump shell structure connected by a cassette, which has good wear resistance, corrosion resistance and high reliability. Gravel pumps have the characteristics of reasonable structure, wide flow channels, reliable operation, large flow rate and long service life. It is especially suitable for the continuous transportation of highly abrasive materials whose particles are too large to be transported by ordinary slurry pumps.
The main use of gravel pumps is to pump mediums such as solids (gravel, sand, and sludge) from one place to another. This process of medium movement is known as slurrification, which involves the introduction of solids into the inlet side of the pump chamber in order to generate a slurry. The slurry is then moved to the desired destination by the power of the pump, which pumps the slurry through the discharge port.
The pumping process of a gravel pump is known as positive displacement. This means that the gravel pump continuously displaces (moves) a set amount of medium with each cycle of the pump. By understanding the difference between positive and negative displacement pumps, it is possible to ensure that the gravel pump is used correctly and efficiently.
The size and type of gravel pump that you need for your application will depend on the scope of the project. For example, if you need to pump sand or gravel for a small pool, you do not need a full-sized gravel pump. A small jet-style pump can do the job just fine. On the other hand, for large-scale operations that involve larger volumes of medium, more powerful and specialized gravel pumps may be necessary. Some of the types of gravel pumps that are used in industrial settings include submersible pumps, centrifugal pumps, and piston pumps, among others.
