The DEPA Series L stainless steel, Hygienic Diaphragm Pumps are suitable for chemical cleaning in place (CIP) or steam sterilisation in place (SIP). They are designed for transfer of abrasive, viscous or shear sensitive media, including products with entrained solids and require minimal maintenance. Because of the low shear, positive displacement pumping action, delicate products including entire chunks of fruit, vegetables and meat can be transported without damage. This gentle action also avoids excessive wear on pump internal components. These pumps use oil free air and require no oil or grease lubrication, so obviating any risk of product contamination by lubricants.
Incorporation of the widely used, threaded milk connections (DIN 11851) ensures that the pumps can be quickly and easily dismantled for visual inspection. Choice can be made from a variety of construction materials for the internal diaphragms and valve balls, to meet exact requirements.
The Series L range are manufactured in four sizes with connections: DIN 15 to DN50. The option of DIN 11851 Tri-clamp, SMS, is also available.

[title_small title=”Overview” /]
Clean In Place (CIP) and Sterilise in Place (SIP) standards are not uniform throughout the world, and our pumps were designed to take into account regional requirements. Consequently, the Series L range is available in polished stainless steel 304 or 316L, with high-gloss clamp bands, and as a DH-UE version in a flanged construction design. By using a large ball valve clearance, our pumps can handle media containing solids, such as pieces of fruit, meat or vegetable, without suffering damage.
