Discharge pulsation dampener
Overview
Discharge pulsation dampener
Fitting a pulsation dampener in the discharge line eliminates up to 90 % of discharge pulsations, protecting the pump and the process pipeline.
Features and benefits
- Increases process uptime and performance by reducing pulsation in pump and process
- Decreases vibration in your system and eliminates pipe hammer to improve pump performance
- In-line, low maintenance set-up, suitable for any Bredel and APEX pump with hose size from 25 mm (1”) to 100 mm (4”)
- Eliminates up to 90% of the pump discharge pulsation between 2 bar (29 psi) and 16 bar (232 psi) pressure
- Certified to meet directive 2014/68/EU by LRQA
