Pneumatic pumps produced by pneumatic pump manufacturers are efficient, safe, and reliable liquid conveying equipment widely used in various fields, which is of great significance for improving production efficiency, reducing energy consumption, and ensuring production safety. In the future development process, pneumatic pumps will continue to improve and innovate, making greater contributions to the development of various industries.

Pneumatic pumps are widely used in industrial production. For example, in the field of chemical engineering, pneumatic pumps can be used to transport various chemical liquids such as acids, bases, salts, benzene, etc; In the petroleum industry, pneumatic pumps can be used to transport crude oil, natural gas, etc; In the food industry, pneumatic pumps can be used to transport various liquid foods such as juice, milk, etc. Due to its characteristics of no spark, no electromagnetic interference, and no temperature rise, pneumatic pumps can also be widely used in flammable and explosive places.

What are the application scenarios of pneumatic pumps?

Application in the chemical industry

Raw material transportation: Pneumatic pumps can transport various chemical raw materials, including corrosive liquids (such as strong acids such as sulfuric acid, hydrochloric acid, nitric acid, and strong bases such as sodium hydroxide and potassium hydroxide) and organic solvents (such as toluene, acetone, methanol, etc.). Due to the corrosive or toxic nature of many raw materials in chemical production, the explosion-proof and leak proof characteristics of pneumatic pumps are particularly important. For example, in the raw material storage area of a chemical plant, pneumatic pumps can safely transport these raw materials from storage tanks to reaction vessels for chemical reactions.

Treatment of reaction products: the products after chemical reaction, whether they are high viscosity polymer solutions (such as lotion of synthetic rubber, plastics, etc.) or suspensions containing solid particles (such as the products after some catalysts participate in the reaction), can be effectively transported by pneumatic pumps. In some polymerization reactions, the viscosity of the product is high, and pneumatic pumps can use their advantage of transporting high viscosity liquids to transport the product to post-processing processes such as filtration, drying, etc.

Dangerous area operation: In hazardous areas of chemical production, such as places with flammable and explosive gases (such as hydrogen, ethylene, etc.), the explosion-proof performance of pneumatic pumps makes them ideal liquid transportation equipment. It can work safely in these areas without causing explosion accidents due to electrical sparks generated by electrical equipment, ensuring the safe operation of chemical production.

Application in the food and beverage industry

Raw material transportation: In food processing, pneumatic pumps are used to transport various food raw materials, such as milk, fruit juice (including fruit juice containing pulp particles), syrup, jam, etc. These raw materials require hygiene and quality to be maintained during transportation. Pneumatic pumps comply with hygiene standards, and their structure (such as diaphragm pneumatic pumps) can prevent excessive contact between liquids and external air or moving parts, reducing the possibility of pollution. For example, on a juice production line, pneumatic pumps can transport freshly squeezed juice from the juicer to storage tanks or blending equipment.

Filling process: During the beverage filling process, the pneumatic pump is responsible for transporting the beverage from the storage tank to the filling head. It can accurately control the flow rate and ensure the accurate amount of liquid in each beverage bottle or can. Meanwhile, due to its excellent self-priming ability, it can continuously and stably provide beverages even when the liquid level of the filling equipment changes, ensuring efficient filling work.

Cleaning and Disinfection Solution Delivery: In the food and beverage production workshop, it is necessary to regularly use cleaning and disinfection solutions to clean the equipment and site. Pneumatic pumps can transport these solutions, such as acidic or alkaline disinfectants, for cleaning pipelines, containers, and production equipment to ensure hygiene and food safety in the production environment.

Application in sewage treatment industry

Sewage transportation: In sewage treatment plants, pneumatic pumps are used to transport sewage containing various pollutants. Wastewater may contain impurities such as sediment, solid waste, oil pollution, fibers, etc. The anti clogging ability of pneumatic pumps enables them to adapt to this complex composition of wastewater. For example, in the primary stage of urban sewage treatment, pneumatic pumps can transport sewage from the sewage collection pipeline to treatment units such as sedimentation tanks and primary sedimentation tanks for the removal of solid impurities.

Sludge treatment: Pneumatic pumps can also play an important role in the sludge generated during the sewage treatment process. Sludge usually has high viscosity and solid content, and pneumatic pumps can transport sludge from sedimentation tanks or sludge concentration tanks to sludge treatment equipment such as sludge dewatering machines or sludge digestion tanks. During the sludge dewatering process, pneumatic pumps can transport chemical agents (such as coagulants) into the sludge to help it dewater better.

Mining industry applications

Slurry transportation: During mining and beneficiation processes, a large amount of slurry is generated. The slurry contains ore particles, soil, and water, and pneumatic pumps can effectively transport this liquid containing solid particles. For example, in a beneficiation plant, pneumatic pumps can transport mineral slurry containing ore particles from the mining site to beneficiation equipment such as flotation machines, magnetic separators, etc. for ore enrichment and separation.

Mineral processing reagent transportation: During the mineral processing, various mineral processing reagents are required, such as flotation reagents (including collectors, foaming agents, etc.), inhibitors, etc. Some of these drugs are liquids, while others are suspensions containing solid particles. Pneumatic pumps can accurately deliver these chemicals to the appropriate positions in the beneficiation equipment, ensuring the smooth progress of the beneficiation process.

Tailings treatment: For the remaining tailings slurry after beneficiation, pneumatic pumps can transport it to tailings ponds or other tailings treatment facilities. Tailings slurry usually contains a large amount of solid waste and a small amount of residual beneficiation agents. The wear resistance and corrosion resistance of pneumatic pumps can meet the long-term stable operation requirements in tailings treatment processes.

Pneumatic pump is a new type of pump equipment driven by compressed air. It has the characteristics of simple structure, small size, light weight, low noise, and easy maintenance, and is widely used in various industrial fields such as chemical, petroleum, pharmaceutical, food, electronics, metallurgy, building materials, etc. The working principle of a pneumatic pump is to drive the piston or diaphragm inside the pump body to move by the force of compressed air, thereby achieving the purpose of suction or delivery of liquid.

Pneumatic pumps are composed of a small number of components, which are easy to disassemble, replace, and repair, greatly reducing maintenance costs. By adjusting the opening and working rhythm of components such as inlet and outlet valves and exhaust valves, the output flow of the pump can be flexibly controlled. Pneumatic pumps do not generate sparks during operation, making them less prone to fire and explosion. And during the liquid transportation process, due to the lack of mechanical seals inside the pump, leakage problems can be avoided.
