White Knight DBU Series Pulse Dampeners

Reduce Pulsation and Increases Batch Yields in Ultra-High-Temperature Applications

Overview

DBU 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 PFU, PSU and PXU Series pumps capable of pressures up to 7 Bar (100 psi) and temperatures of 210°C (410°F).

DBU030 dampeners fit 30 and 60 lpm pumps, and DBU060 dampeners 30, 60 and 140 lpm pumps.
