Air Operated Diaphragm Pumps in Cast Metal
DEPA air operated diaphragm pumps made of cast metal have established themselves over decades in various industrial areas. 
The DEPA Series M Air-Operated Diaphragm Pumps were developed for the smooth transfer of abrasive, solids-containing and viscous media. The direct pneumatic drive means that there is no need for electric driven motors, base plates and couplings.
The compact and efficient designs are easy to transport, and are therefore flexible enough to use on construction sites, mining applications as well as in stationary operation in different industries.
Bodies made of cast aluminum AL 233, ductile iron GGG 40, cast stainless steel 316L and Hastelloy C are available so that the pumps can be individually adapted to transfer tasks. The elastomer materials for diaphragms, valve seats and valve balls have to be selected from the compatibility list.
World-wide installations on ships, well-known ceramic manufacturers, in spray painting systems and automobile industry and in mining are amongst their many varied applications.
In the range of cast metal pumps more than 20 models with different sizes and designs are available to serve almost any type of application. The sturdy cast metal construction ensures high abrasion resistance when pumping abrasive media, a low flow resistance due to the high surface finish, availability throughout a wide temperature range, excellent corrosion resistance and a long lifetime.
Size range: DN15-DN80 (0.5"-3")
