What is a dry sand transfer pump?
What is the difference between a dry sand pump and a wet sand pump?
The main difference between a dry sand pump and a wet sand pump lies in the transfer medium and material state:
Dry sand pump: Mainly used to convey dry, granular materials (such as dry sand) with no or very little water content. It uses gas (such as air or nitrogen) as the transfer medium and conveys by pneumatic principle. It is suitable for materials that need to avoid moisture, or for occasions where dry powders and particles need to be conveyed over long distances, with high efficiency and low pollution.
Wet sand pump: Mainly used to convey a mixture of solid particles containing a large amount of liquid (usually water), that is, slurry (such as mud, wet sand, ore slurry, coal slime, etc.). It uses liquid as the main medium and generates centrifugal force through the rotation of the impeller to push the slurry out. It is suitable for handling fluids with high viscosity and containing solid particles, such as mining, dredging, sewage treatment, ash treatment in the power industry, etc. Wet sand pumps are usually designed to be wear-resistant and corrosion-resistant.

Advantages of dry sand pump
Dry sand faces many challenges in the transportation process, such as environmental pollution and health hazards caused by flying dust, blockage caused by moisture and agglomeration of materials, and severe wear of traditional mechanical equipment by dry materials. Traditional methods such as belt transfer or manual handling are not only inefficient, but also difficult to overcome the above problems. The dry sand transfer pump effectively solves these problems through its unique pneumatic transfer principle: it uses closed pipeline transportation to fundamentally eliminate dust leakage, significantly improves the working environment, and protects the health of workers.
In addition, the dry sand transfer pump can accurately control the air flow speed and pressure in the pipeline. Even in the face of fine dry sand particles, it can maintain a stable and continuous fluidization state to avoid material accumulation or agglomeration in the pipeline, thereby greatly reducing the risk of blockage. In view of the abrasiveness of dry sand, modern dry sand transfer pumps usually use wear-resistant pipeline materials and special lining designs, and by optimizing the transfer speed and elbow design, reduce the impact and friction between the material and the pipeline wall, effectively extend the service life of the equipment and reduce maintenance costs.
What is the purpose of the dry sand transfer pump?
The dry sand transfer pump is mainly used to achieve efficient transportation of dry sand materials in closed pipelines, and is widely used in building materials, casting, chemical industry, power and other industries. In the dry-mix mortar production line, it can be used to transport dry sand from the storage bin to the mixing system to achieve automatic feeding; in the foundry workshop, the dried molding sand can be transported to the molding station to improve the sand loading efficiency and avoid dust pollution; in quartz sand deep processing enterprises, the dry sand transfer pump can undertake the task of transferring materials from the drying section to the grading and packaging section, reduce manual intervention, and improve cleanliness; in addition, in cement plants, glass plants and other powder transfer places, this equipment is also often used to accurately deliver dry sand to the feeding port or reactor to meet the requirements of closed and efficient transfer. This pump is particularly suitable for working environments with high requirements for transfer accuracy, continuity and environmental protection.
