White Knight DBA Series Pulse Dampeners

Reduce Pulsation and Increases Batch Yields in Ambient Temperature Applications

Overview

DBA Series in-line and top-mount dampeners reduce system pulsation to improve flow control, increase yields, protect components, and minimize downtime for repairs. They are designed for PFA, PSA and PXA Series pumps capable of pressures up to 7 Bar (100 psi) and temperatures of 100°C (212°F).

DBA030 dampeners fit 30 and 60 lpm pumps; DBA060s fit 30, 60 and 140 lpm pumps; and DBA140s fit 60 and 140 lpm pumps.
