Gravel pumps are typically used to move slurry, or a mixture of solid particles and water, from one location to another. Gravel pumps are equipped with motor and bearing housing, which help in maintaining the balance of the pump while it is running. The motor transmits the power to the pump shaft, while the bearing housing supports the bearings and the other components. Gravel pumps have a range of applications. They are used in river dredging and dewatering, as well as in underground and open-pit mining. They can also be used to move tailings, as well as for saltwater disposal and desalination.
Gravel pumps are specially designed for pumping gravel, sand, and other granular material. They are usually high pressure pumps and the flow rate can be controlled by adjusting the impellers. The key components consist of a pump casing, impellers, and shafts.
The pump casing of a gravel pump is generally made from metal or metal alloys such as steel, cast iron, or stainless steel. The casing ensures that the pressure of the water or other fluids follows the design characteristics of the pump. The casing also helps the pump to handle different types and sizes of substances without any adhesion or damage.
The impellers are the main components of a gravel pump. They are responsible for the flow rate and pressure of the material being pumped. Impellers can be made of alloys such as cast iron, stainless steel, and bronze. The impellers also come in a variety of sizes and shapes, like radial, mixed flow and axial-flow.
The shafts are the moving parts inside a gravel pump and serve to transfer the power from the pump’s motor to the impellers. Each shaft has a specific purpose, such as controlling the flow rate, stabilizing the pressure, or regulating the speed of the impeller. The shafts are usually made from alloys such as stainless steel and cast iron.
