AIR-OPERATED DOUBLE-DIAPHRAGM PUMPS | PRODUCT BROCHURE Where Innovation Flows

The Almatec® C-Series Air-Operated Double-Diaphragm (AODD) Pump is a cost-effective, reliable and superior-built alternative and features a solid design suitable for a wide array of pumping tasks. The distinctive and proven solid design provides the mass needed for an oscillating pump. The suction and discharge ports are available as separate housing parts. In addition to the standard connection, two further connection footprints are available to match existing installations. The ring tightening structure, good suction head, self-priming and dry run capability as well as the absence of...

FUNCTIONAL PRINCIPLE The ALMATEC C-Series is based on the functional principle of double diaphragm pumps. The basic configuration consists of two external side housings with a center housing between them. Each of the side housings contains a product chamber which is separated from the center housing by a diaphragm. The two diaphragms are interconnected by a piston rod. Directed by an air control system, they are alternately subjected to compressed air so that they move back and forth. In the first figure, the compressed air has forced the left-hand diaphragm towards the product chamber and...

VISCOSITY AND PUMP CAPACITY The capacity specified in the pump performance charts generally refer to water (1 mPa-s). The value must be reduced correspondingly when pumping liquids with higher viscosity. The design capacity can be read off directly from the graph and the corresponding pump size selected. The example shown here is based on a required capacity of 10 m3/h with a product viscosity of 6000 mPa-s. The dash-dotted line intersects the design capacity scale at 17 m3/h.
