AODD Metal Pumps – Reliable Air Operated Pumps for Demanding Industrial Processes

Industrial processes often require pumps capable of handling abrasive fluids, corrosive chemicals, solvents, oils, sludge, and liquids containing suspended solids. Conventional centrifugal pumps may struggle with these demanding applications, making Air Operated Double Diaphragm (AODD) Metal Pumps the preferred solution.

At NIMIS INDIA, we supply high-performance AODD Metal Pumps engineered for dependable operation, low maintenance, and superior durability across a wide range of industries. These pumps are powered entirely by compressed air, eliminating the need for electric motors and making them ideal for hazardous and explosion-prone environments.

Whether you need to transfer chemicals, wastewater, petroleum products, paints, adhesives, or slurries, our metal diaphragm pumps provide exceptional performance with outstanding reliability.

What is an AODD Metal Pump?

An Air Operated Double Diaphragm (AODD) Metal Pump is a positive displacement pump that uses compressed air to alternately move two diaphragms, creating suction and discharge without requiring electrical power.

Because there are no rotating mechanical seals, AODD pumps are capable of handling viscous fluids, abrasive media, solids, and shear-sensitive products with minimal maintenance.

Their self-priming capability and ability to run dry make them one of the most versatile industrial pumps available.
