Almatec Metal CHEMICOR AODD Pump

Almatec CHEMICOR Series Stainless-Steel AODD Pumps

When developing Almatec® CHEMICOR Series Stainless-Steel Air-Operated Double-Diaphragm (AODD) Pumps, special attention was paid to the shape of the product chambers. The result is a pump design that offers soft changes in direction, smooth flows and no dead corners. The pump image shows a model with optional draining system.

CHEMICOR Series pumps are manufactured from stainless steel 1.4408/SS316 (G-X 6 CrNiMo 18 10), which is a cast steel that is resistant to corrosion and acids, and is frequently used for fittings and pump casings because of its good general chemical stability. This material in a precision lost-wax casting is used for the wetted housing parts of the CHEMICOR Series. The lost-wax process is a complex casting process yielding a smooth and dense surface with increased resistance to corrosion.
