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
Reduces discharge pulsation, lessens vibrations 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 to 100 mm
Eliminates up to 90 % of the pump discharge pulsation between 29 psi and 232 psi pressure
Certified to meet directive 2014/68/EU by Lloyds register
