Almatec C-Series The Cost-Effective Plastic AODD Pumps

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 suction and discharge ports are available as separate housing parts. In addition to the standard connection, two further connection foot-prints 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 drives, rotating parts and shaft seals are further features.
