The Aluminum Body Pneumatic Diaphragm Pump is a versatile and durable fluid transfer solution designed for handling corrosive, viscous, abrasive, and flammable media across a wide range of industries. Its lightweight aluminum construction provides good strength-to-weight performance and corrosion resistance, while the air-operated design eliminates the risk of sparks and leakage.
Industrial Applications
Chemical and Petrochemical Industry
Suitable for transferring acid and alkali solutions such as sulfuric acid and sodium hydroxide, as well as solvents like methanol, ethanol, and various resins or coatings.
Commonly used in acid and alkali wastewater treatment in chemical plants, solvent transfer in petrochemical facilities, and raw material conveying in paint manufacturing.
Environmental Protection and Water Treatment
Efficient for handling wastewater, sludge, slurry, and chemical dosing operations.
Widely applied in sewage treatment plants for sludge transfer, river dredging projects for slurry extraction, and dosing systems for coagulants and disinfectants.
Food and Pharmaceutical Industry
Designed to transport food-grade materials such as syrup, juice, and milk, as well as pharmaceutical intermediates and liquid medicine.
When equipped with sanitary materials such as stainless steel and PTFE diaphragms, it ensures hygienic operation and prevents media contamination.
Mining and Metallurgy
Ideal for pumping mineral slurry, tailings, and liquids containing metal particles under abrasive conditions.
Commonly used in mining slurry pipelines and metallurgical wastewater treatment processes.
Agriculture and Civil Applications
Used for pesticide spraying, irrigation water transfer, and domestic applications like sewage lifting and RV water supply.
Effective for agricultural spraying systems, basement wastewater discharge, and compact washing or water distribution units.
