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.
In-line DBU060 pulse dampener with
PSU060 ultra-high temperature pump.
Top-mounted DBU060 pulse dampener with PSU060 ultra-high-temperature pump.
Features & Benefits
- Up to 93% pulsation reduction minimizes system vibration to protect components, minimize down time for repairs, and increase chip yield
- Flow-specific models for 30, 60, and 140 lpm pumps
- Top-mount and in-line options in various sizes to increase dampening or reduce footprint
- Auto-leveling provides constant, active adjustment for more system control and increased chip yields
- Dead-head capable operation
- Process-safe PTFE and PFA flow paths for harsh applications
- Metal-free design provides safe, leak-free operation without possibility of contamination
- Minimal parts for durable design
- Class 100 cleanroom assembly, testing, and packaging
- Easy to install and service
- Various liquid connection options
