Trending best features of FLOWGUARD PULSATION DAMPERS 2025

Flowguard pulsation dampers (also known as dampeners) are hydro-pneumatic devices designed to eliminate pulsations, vibrations, and noise from positive displacement pumps. Using them in fluid systems improves instrument accuracy, extends pump life, and reduces maintenance and operational costs. They also prevent pipe fractures caused by vibration and protect personnel from leaks.

Flanged Connection. Flowguard pulsation dampers feature a sealed volume of inert gas, typically nitrogen, contained within a flexible membrane inside a noncorrosive shell.

When a pressure pulse occurs, part of the fluid energy compresses the gas. As

pressure decreases, the gas expands, releasing the stored energy back into the

system. This action dampens pressure fluctuations and minimizes vibrations. Design Efficiency

Flowguard dampers feature a simple yet highly efficient design, outperforming traditional hydraulic accumulators. Their rugged construction ensures reliability, affordability, and easy maintenance. Our standard housings are made from non-corrosive 316 stainless steel, polypropylene, or specialty alloys including Inconel, Titanium, Hastelloy, and Monel™. The membrane is available in a wide variety of elastomers, PTFE (Teflon®) diaphragms, and PTFE or stainless steel bellows.

Broad Range to Fit Your Needs CoorsTek provides a wide range of Flowguard

pulsation dampers to accommodate pressures from 150 psi (10 bar) to 15,000 psi (1,000 bar) and may be custom made to meet any specification or a particular

duty requirement.

Certified High Quality

Designed and manufactured to the highest standards, Flowguard pulsation dampers are supplied to internationally recognized pressure vessel design codes and standards to satisfy customer requirements.
