Based on double hose structure with expansive inner hose, reinforced outer hose, and compressed air in between, Flowrox Expulse absorbs up to 90% of pulsations, settling restless pipes, pressure peaks, and uneven flows. Product is naturally resistant to wear, corrosion, and most chemicals. Designed to clean itself on every pulse, dampener does not collect sediment or particles. It also compensates for misalignments of pipeline and provides flexible connection to pump.
