Applications Pharmaceutical and Cosmetic Pharmaceutical and Cosmetic process applications call for demanding hygienic standards and efficient “cleanability” of system components. DEPA® pumps accommodate these requirements with their design and polished surfaces, CIP (cleaning in place) & SIP (sterilization in place). (Pictured) DEPA® 1” polished stainless steel pumps for hydrogen peroxide + additives in a hair colour production process Food DEPA® pumps were designed with an unimpeded flow-path, providing smooth transfer of product, which generates minimal shear effect even with large solid content....

Interchangeable Design A key design concept of our DEPA® Air-Operated Double Diaphragm Pumps is a modular, compact design. Fewer parts lead to pump efficiency thereby reducing downtime and parts inventories. Our pumps can easily be modified to switch from one application to another simply by changing the diaphragms, balls, and seats. Note: The illustration shows the typical arrangement of the clampband version DL. The DH version is refered to as the flanged design as the pump chambers are bolted to the centre block.

Air Control Air Valve In applications distributed across the globe, DEPA® Air-Operated Double Diaphragm Pumps are subjected to impressive ranges of operating temperatures, pressure fluctuations, full load, and intermittent operating conditions. This often places severe demands on the air valve responsible for the distribution of air in the individual chambers, therby regulating the operation of the pump. In order to meet the emerging requirements of industry, DEPA® engineers conduct ongoing intensive research and development work to maintain “state-of-the-art” status for our products. Functional...

Materials and Selection Elastomer Materials (for Diaphragms) The characteristics of various elastomer compounds are taken into account in the selection of diaphragm materials to match the chemical and mechanical requirements of particular applications. The design of DEPA® diaphragms incorporates technological advances developed over years of field experience. Our stateof-the-art manufacturing process directly contributes to the extended lifetime of our diaphragms. A remarkable part of the process is the use of fabric that is integrated during forming within the elastomer, enhancing stability....

Metallic Pumps, Series M - Type DL Overview DEPA® Air-Operated Double Diaphragm Pumps made of cast metal have proven themselves over decades in various industrial applications. The myriad of established applications across the globe include installations on ships, at well-known ceramics manufacturers, in spray painting systems (in the automobile industry), and in mining operations, among countless others. The sturdy cast metal construction provides high resistance to abrasive media and a low flow resistance, owing to its polished surface. They are available in a wide selection of temperature...

Metallic Pumps, Series M - Type DH Overview DEPA DH® Next Generation Air Operated Double Diaphragm Pumps for industrial applications are made of cast aluminum. The flexible, multiport manifold can be customized to plant specifications and provides up to 25 connection options to accommodate various operational requirements. DEPA DH® pumps feature cast feet integrated in the center block housing that enable maintenance in place (MIP). This unique design can reduce downtime by up to 25%* and optimizes assembly and disassembly through a 30%* reduction in required parts. Rubber feet can be easily...
