Particles, sediment, and abrasive materials can clog flow passages, damage the impeller, and accelerate wear on pump components. One technology that can be used for these applications is the Air Operated Double Diaphragm (AODD) Pump.<\/p>\n<p style=\"text-align: justify;\">An AODD Pump is a positive displacement pump powered by compressed air. It uses two diaphragms that operate alternately to draw in and discharge the fluid. Since it does not rely on a rotating impeller, an AODD Pump can be a suitable option for handling viscous, abrasive, corrosive, or certain solid-laden fluids.<\/p>\n<h2><strong>Why Are Solids a Challenge?<\/strong><\/h2>\n<p style=\"text-align: justify;\">Fluids containing solids can be found in wastewater treatment, mining, chemical processing, oil and gas, petrochemical, and manufacturing applications. These fluids may take the form of slurry, sludge, sediment, fibers, or solid particles suspended in a liquid. The level of difficulty depends on the size, shape, hardness, and concentration of the particles:<\/p>\n<ul>\n<li><strong>Hard or sharp particles:<\/strong> Can potentially erode internal pump components.<\/li>\n<li><strong>Long fibers:<\/strong> Can become entangled and clog flow passages.<\/li>\n<li><strong>High solids concentration:<\/strong> Can increase viscosity and flow resistance.<\/li>\n<\/ul>\n<p>Therefore, flow capacity alone is not enough when selecting a pump for solids-handling applications. You should also check the fluid passage diameter, check valve configuration, wetted-part materials, operating pressure, and maximum allowable solids size.<\/p>\n<h2><strong>Key Advantages of AODD Pumps<\/strong><\/h2>\n<p style=\"text-align: justify;\">AODD Pumps feature relatively open flow passages and use a check valve system to control the direction of fluid flow. This configuration allows them to handle certain types of suspended solids without relying on a rotating impeller.<\/p>\n<p style=\"text-align: justify;\">Another advantage is their ability to handle changing fluid conditions. During a process, fluid viscosity and solids concentration may vary. An AODD Pump can adjust its flow rate by regulating the compressed-air supply, provided the pump remains within its specified operating limits.<\/p>\n<p style=\"text-align: justify;\">Certain AODD Pump configurations also offer self-priming capability. This can be beneficial when the pump is installed above the liquid level or used for tank-draining applications. Some configurations can also tolerate dry-running for limited periods; however, this capability must always be confirmed based on the specific pump model and diaphragm material.<\/p>\n<p style=\"text-align: justify;\">Because AODD Pumps do not use a conventional mechanical shaft seal, the potential for leakage through a shaft-sealing area can be reduced. This characteristic can be particularly valuable when handling corrosive, contaminated, or hazardous fluids.<\/p>\n<h2><strong>ALMATEC AODD Pumps<\/strong><\/h2>\n<p><img decoding=\"async\" src=\"https:\/\/winstonengineering.com\/id\/wp-content\/smush-webp\/nc\/p\/3\/0\/6\/306-510x340.jpg.webp\" alt=\"Plastic AODD Pumps\" \/><\/p>\n<p><a href=\"https:\/\/winstonengineering.com\/id\/en\/product\/plastic-aodd-pumps-1\/\"><strong>ALMATEC AODD Pumps<\/strong><\/a> can be considered an effective solution, particularly when solid particles are suspended in corrosive chemical fluids.<\/p>\n<p>These pumps are available in PE (Polyethylene) and PTFE materials, including conductive variants for specific applications and operating environments:<\/p>\n<ul>\n<li><strong>PE material:<\/strong> A suitable choice for applications where corrosion resistance is required, particularly compared with conventional metal pump materials.<\/li>\n<li><strong>PTFE material:<\/strong> Offers excellent compatibility with a wide range of aggressive chemicals and is widely used for components that come into direct contact with the fluid.<\/li>\n<\/ul>\n<p>According to the Winston Engineering catalog, ALMATEC pumps are available with capacities of up to approximately <strong>600 liters per minute<\/strong> and operating temperatures of up to approximately <strong>120\u00b0C<\/strong>. Actual performance depends on the pump size, material, diaphragm type, and configuration.<\/p>\n<p style=\"text-align: justify;\">ALMATEC pumps can be considered for applications in wastewater treatment, chemical processing, pharmaceutical manufacturing, oil and gas, and petrochemical industries. When handling chemical mixtures containing solids, make sure that all wetted-part materials have been verified against the manufacturer&#8217;s chemical compatibility chart.<\/p>\n<h2><strong>Conclusion<\/strong><\/h2>\n<p style=\"text-align: justify;\">Both Wilden and ALMATEC product lines are designed to provide reliable pumping solutions for specific application requirements, including general solids handling, slurry transfer, and corrosive chemical fluids.<\/p>\n<p style=\"text-align: justify;\">To determine the most suitable pump configuration, a comprehensive assessment of the solids size, solids concentration, chemical properties, operating pressure, and temperature is essential.
