GENERAL DESCRIPTION DUOTEK Pulsation Dampeners
The active pulsation dampener is the most effective way to eliminate pressure variations at the pump outlet. The DUOTEK pulsation dampener works actively with compressed air and a diaphragm, automatically adjusting the correct pressure to minimise pulsation.
Pulsation dampeners require minimal maintenance and, depending on the application requirements, are available in the same body and diaphragm materials as the pump.
They are specifically designed for demanding applications in potentially explosive atmospheres (ATEX Certification).
SEKO Duotek dampers guarantee a significant reduction of pulsation in rising mains, with an average pulsation reduction of 70%-80% in high back pressure applications.
There is a special FDA-compliant version, made of electropolished AISI 316, which is specifically used in the food industry.
The parts in contact with the liquid have been chosen to ensure full compatibility with most commonly used chemicals. Due to the variety of chemicals available on the market, it is recommended to check the chemical compatibility between the dosed product and the materials in contact. Please refer to the attached document "Chemical compatibility of Seko air operated pumps" for this information. If you have any questions, we will be pleased to answer them.
