The Expulse Pulsation Dampener from Flowrox settles pipeline pressure peaks and uneven flow. Dual hose technology with an outer reinforced layer for pressure retention and an inner flexible process layer creates an expansive cavity for air changes capable of absorbing up to 90 percent of the pulsation caused by pumping. The in-line design allows for both vertical and horizontal installation, providing greater flexibility when dealing with tight installations. It relieves the stresses of breaking diaphragms or bladders and is naturally resistant to wear, corrosion and most chemicals, giving it a long product life cycle. The dampener cleans itself on every pulse and doesn’t collect sediment or particles. It combines a pulsation dampener with a connection hose for ease of pump maintenance and alleviation of pipe stresses. It is easy to install on any pulsating pump from any manufacturer. 410/636-2250; www.flowrox.us.
