What Do You Need to Know About Gravel Pumps?

What is a Gravel Pump?

A gravel pump is a specialized type of pump designed to handle and transport abrasive materials, particularly gravel, sand, and slurry. It is widely used in industries such as mining, dredging, and construction, where the efficient movement of these materials is essential.
Gravel pumps are typically centrifugal pumps, which means they use rotating impellers to create centrifugal force and propel the material through the pump. These pumps are specifically designed to withstand the harsh conditions associated with handling abrasive materials, such as high solids content, large particle sizes, and corrosive environments.

Key Components of a Gravel Pump

A gravel pump consists of several key components that work together to facilitate the handling and transportation of abrasive materials. Let&#;s take a closer look at these components and how they function:

• Impeller: The impeller is a rotating component with vanes or blades that create centrifugal force. As the impeller spins, it imparts kinetic energy to the fluid, pushing it outward and generating pressure.
• Casing: The casing is a stationary housing that surrounds the impeller. It directs the flow of the material and helps maintain the efficiency of the pump. The casing often has a wear-resistant lining to withstand the abrasive nature of the pumped material.
• Suction Pipe: The suction pipe connects to the inlet of the pump and is responsible for drawing in the material from the source. It may include a strainer or screen to prevent large debris from entering the pump.
• Discharge Pipe: The discharge pipe is connected to the outlet of the pump and transports the material to the desired location. It may include additional fittings or valves to control the flow rate and direction.
• Motor or Diesel Engine: The motor or power source provides the necessary energy to drive the pump. Gravel pumps can be powered by electric motors or diesel engines, depending on the specific application and requirements.

How Does a Gravel Pump Work?

The operation of a gravel pump can be summarized in the following steps:

• Priming: Before starting the pump, the suction pipe and casing need to be filled with fluid to create a vacuum. This process is known as priming and ensures that the pump can effectively draw in the material.
• Material Intake: Once the pump is primed, the rotating impeller creates a centrifugal force that draws the material into the pump through the suction pipe. The impeller blades accelerate the material, increasing its velocity.
• Centrifugal Action: As the material enters the casing, the curved shape of the casing and the high-speed rotation of the impeller cause the material to move in a circular motion. The centrifugal force generated by the impeller pushes the material towards the casing walls.
• Pressure Generation: The material is then forced out through the discharge pipe due to the increasing pressure within the casing. This pressure is a result of the centrifugal force and the design of the pump components, including the impeller and casing.
• Material Transport: The material is transported through the discharge pipe to the desired location, where it can be deposited or further processed as required.

Gravel pumps are designed to handle abrasive materials efficiently and reliably, thanks to the combination of centrifugal force and durable components that can withstand the wear and tear caused by the particles being pumped.

Five models to choose, from 90 m3 /hour to 554 m3 /hour. Configured as a highly efficient, shaft driven, direct drive Vertical (Submersible) Slurry Pump / Gravel Pump, which can be used as a semi-submersible pump to a depth of 1.2 &#; 1.6 meters (depending on the model). Primarily used in hydraulic sluicing, as the most efficient means of slurry ore transport from the hydraulic sluicing mining area to the wash plant site, away to the wash plant site. Used whenever trucking the ore is unapplicable or not feasible. The other usage is for removing and transporting slurry ore from a temporary tailings dam at the treatment plant site, away to a permanent disposal dam site.

The other usage is for removing and transporting slurried ore from a temporary tailings dam at the treatment plant site, away to a permanent disposal dam site.

Highly efficient tool for breaking and disintegration of heavy clay, configured either after Trommel or Grizzly Separator and prior to the concentration of minerals contain in heavy & sticky clay ore. These models are mounted on robust enclosed skid frames for protection and foot suspending below a tri-frame if required. The pump can then be suspended above the pump medium i.e waste treated ore, for convenient positioning.
