White Knight DBH Series Pulse Dampeners

Reduce Pulsation and Increases Batch Yields in High-Temperature Applications

Overview

DBH 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 PFH, PSH and PXH Series pumps capable of pressures up to 5.5 Bar (80 psi) and temperatures of 145°C (293°F).

DBH030 dampeners fit 30 and 60 lpm pumps; DBH060s fit 30, 60 and 140 lpm pumps; and DBH140s fit 60 and 140 lpm pumps.
