Almatec's Plastic AODD

The range of plastic air-operated double-diaphragm (AODD) pumps by Almatec exceeds industry quality requirements by incorporating standard features and complementing them with a solid block design, energy-efficient air control system, cutting-edge diaphragms, and best-in-class materials. A solid body construction adds to the pumps’ stability and operation’s safety level. Also being mechanically machined using CNC technology, the perfect tolerances between the walls and the parts are achieved. Almatec plastic AODDs are manufactured using PE or PTFE, making them economical to own.

Almatec pumps follow the conventional working principle of an AODD pump. They move fluid by the alternate and repeated back-and-forth movement (strokes) of two flexible membranes or diaphragms mounted on a common shaft. Although diaphragm pumps can be driven directly, with the shaft connected directly to a motor, AODD pumps use compressed air with a sophisticated distribution system directing the air alternately to two air chambers on the opposite sides of the diaphragms.

AODD pumps are capable of handling abrasive, highly viscous fluids, sludges, slurries, and shear-sensitive fluids. AODD pumps are robust, reliable, easy to maintain, and relatively low cost. They tend to be general workhorse devices and are typically used for transfer applications in a wide variety of industries.
