An AODD pump (Air Operated Double Diaphragm) is one of the most reliable and versatile solutions for industrial fluid transfer. Designed to efficiently and safely handle a wide range of liquids, it is capable of operating with abrasive, viscous, flammable and extreme temperature fluids. Its robust construction and the wide range of materials available for key components make it suitable for highly demanding sectors, such as the chemical, food, energy and water treatment industries. In this article, we will look at the main types of fluids that can be handled with AODD pumps.
Handling abrasive fluids
Handling abrasive fluids such as paint with metal flakes, epoxy resins with zinc particles or industrial sludge can quickly compromise the internal components of an inadequately designed pump, causing premature wear, loss of efficiency and costly downtime. In this case, the recommended materials for handling abrasive fluids are stainless steel (SS316) or technical plastics such as POLYPROPYLENE or PVDF (polyvinylidene fluoride). To address these critical issues, it is essential to select construction materials that guarantee high mechanical, chemical and wear resistance. Stainless steel (SS316), for example, offers considerable corrosion resistance and mechanical strength ideal for aggressive and abrasive environments. PVDF (polyvinylidene fluoride) stands out for its excellent chemical resistance and dimensional stability, making it ideal for applications with aggressive or highly abrasive fluids, while for abrasive but chemically less reactive fluids, POLYPROPYLENE is the best choice. Debem’s AODD pumps designed for abrasive fluids incorporate reinforced balls and seats to ensure reliable sealing and to prevent damage due to prolonged contact with solid particles. Optimized internal volumetric profiles reduce mechanical wear, prolonging the life of the pump.
Transporting viscous fluids
Handling high viscosity fluids, such as food sauces, industrial adhesives or resins, requires pumps capable of guaranteeing constant and efficient transfer, avoiding hiccups or pressure drops that could compromise the entire production process. Debem pumps dedicated to handling viscous fluids feature optimised volumetric profiles designed to reduce internal resistance during liquid transfer. This feature allows for greater flow efficiency, avoiding the risk of cavitation or operational blockages. Another distinctive feature is the pumping cycle adjustment, which allows the pump’s operation to be adapted to the specific viscosity of the fluid. This flexibility ensures greater operational precision and a reduction in energy consumption and wear of internal components. Finally, the use of high-quality components ensures a long pump life, even in continuous operation and with particularly dense fluids.
Pumping flammable fluids
Handling flammable fluids, such as industrial solvents, fuels and volatile chemicals, requires the application of strict safety standards to prevent accidents and ensure reliable operations. Thanks to their pneumatic operation, double diaphragm pumps eliminate the risk of electrical sparks, making them the ideal solution for ATEX-rated or potentially explosive environments. For maximum safety, these pumps are designed with a grounding system, which prevents the build-up of dangerous electrostatic charges during fluid transfer. In addition, their ATEX certification ensures their compliance with European regulations for hazardous areas, thus offering a reliable level of protection in critical environments. Operationally, Debem’s diaphragm pumps for flammable fluids are designed to operate continuously and safely, ensuring stable transfer and minimising the risk of leakage or malfunction.
