Key Industries:

Pharmaceutical and Cosmetic

Pharmaceutical and Cosmetic process applications call for demanding hygienic standards (EHEDG, FDA, and 3A) and efficient “cleanability” of system components. DEPA® pumps accommodate these requirements with their design and polished surfaces (up to 0,5 μm) permitting in-place cleaning and sterilization.

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.

Paint and Varnish

Paints and varnish production utilizes unique applications. Two of these applications are dosing of chemicals and mixing of paints. A commonly found process—transfer of solvents—can create an explosion-prone atmosphere. Our DEPA® pumps operate safely under these conditions, and come with full ATEX certifcation for your peace of mind.

Tanks/Cisterns - Evacuation (or transfer between vessels)

DEPA® pumps operate effectively in applications such as emptying of mobile and stationary tanks. Their high flow rate speeds up this process. The media transferred (pumped out) can vary from solvents and acids to alcali or other products.
 

Industrial & Chemical

The selection of available housing and elastomer materials make our pumps adaptable for most highly aggressive or corrosive media. DEPA® pumps’ outstanding chemical resistance and robust design contribute to a reliable and safe operation.
