Air Operated Double Diaphragm

From the most aggressive chemicals to potable water, the Duotek range of air-operated double-diaphragm pumps represents one of SEKO’s most versatile dosing and liquid transfer solutions.

Excellent chemical compatibility courtesy of premium materials such as Hytrel, Santoprene, EPDM, PTFE, 316 stainless steel and more means the Duotek AODD pumps can handle liquids as diverse as acids, paints, adhesives and carbonated drinks. This, combined with a superior capacity for moving highly-viscous media, allows Duotek to be used in a virtually limitless range of applications. 

Special versions of the Duotek AODD pump include an FDA-approved model with food-grade electro-polished stainless-steel construction. Meanwhile, the complete absence of electrical components makes Duotek fully submersible and ATEX-compliant for use in explosive atmospheres.
