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
  • 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 (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 Lloyds register
