Versatile Applications Across Industries

The AODD pump is engineered to handle a broad spectrum of fluids including corrosive chemicals, abrasive slurries, viscous liquids, solvents, and even sensitive food products. Its compatibility with various construction materialssuch as Aluminium, Polypropylene, Stainless Steel, and PTFEmakes it adaptable for use in chemical processing, food manufacturing, pharmaceuticals, and wastewater treatment, among other industries.

Reliable Performance & Safety Features

This pump delivers a maximum pressure of 100 PSI (7 bar) and supports air inlet pressures between 2 and 7 bar, accommodating different process requirements. The leakage-free double diaphragm design minimizes the risk of fluid loss and contamination, while its self-priming capability ensures efficient startup. Optional inline filters add further process protection for both the pump and downstream equipment.

Easy Installation and Maintenance

Portable and floor-mountable, the AODD pump streamlines installation for both temporary and permanent setups. Bolted or clamped construction allows for rapid maintenance and part replacement, minimizing downtime. Its pneumatic operation eliminates the need for electric power, increases safety in hazardous environments, and reduces the need for extensive wiring or electrical approvals.

FAQs of Air Operated Double Diaphragm Pump:

Q: How does the self-priming feature of the AODD pump benefit operations?

A: Self-priming enables the AODD pump to start pumping fluids without pre-filling, even when the suction line is dry. This simplifies start-up procedures, prevents air binding, and reduces downtime, especially in applications with intermittent or unpredictable flow.

Q: What types of fluids and materials can the AODD pump handle?

A: The pump is suitable for transferring a diverse range of fluidsincluding chemicals, abrasive slurries, viscous liquids, solvents, food products, and even corrosive or abrasive materialsthanks to its various material options such as PP, SS304, SS316, Aluminium, and PTFE.

Q: When should inline filtration be used with this pump?

A: An inline filter is recommended to protect the pump and downstream equipment when handling fluids containing particulates or debris. This is especially important in applications processing slurries or solids up to 6 mm, ensuring reliable and long-lasting pump performance.

Q: Where can this pump be installed, and how portable is it?

A: The AODD pump can be both portable and floor mounted, allowing flexibile installation in fixed plant setups or as a mobile solution for on-site fluid transfer tasks. Its compact size and reasonable weight make it suitable for a variety of environments, including tight industrial spaces.

Q: What benefits does pneumatic operation offer for industrial users?

A: Pneumatic (air-operated) action eliminates the need for electric connections, making the pump safe for use in hazardous or explosive atmospheres. It also lowers noise levels to below 70 dB, promotes safety, and reduces maintenance associated with electrical components.

Q: How does the pumps seal design prevent leaks?

A: The pump uses a double diaphragm, leakage-free seal system. This prevents fluid leakage and cross-contamination, making it ideal for handling hazardous or valuable materials while maintaining workplace safety and product integrity.
