Flowrox™ Expulse™ pulsation dampener

Smooth and quiet flow

Flowrox Expulse pulsation dampener has an important job to minimize pulsation distractions, a common issue with several types of positive displacement pumps. Pulsations can result in annoying noise and vibrations in the process pipeline, which can potentially lead to breakages over time.

Simple and insensitive

Easy and fast to maintain. Resistant to wear, corrosion and most chemicals.

Saves energy

Absorbs up to 90% of pulsations and saves up to 10% of energy by temporarily storing it to the flexible inner hose and filler gas.

Quiets noise

Quiets the annoying noise of the pulsating pump in the pipelines.

Easy, independent and reliable

Easy to install on any pulsating pump type from any manufacturer in the market. There are no breaking diaphragms or bladders.

Protects pump bearings and gearbox

Reduces hammering of the pipeline and pump.

Fluent processes without distractions

We offer an ideal solution to this problem: Flowrox Expulse. This innovation will help you to achieve the dream of any plant operator – fluent processes without any distractions. Flowrox Expulse is a flexible inline pulsation dampener which quiets noise while settling pressures peaks and uneven flows. The design is based on a double hose structure with an expansive inner hose, reinforced outer hose and compressed air between the layers.

Simple and intensive pulsation dampener

Flowrox Expulse is the simplest and most robust inline pulsation dampener on the market. It quiets the banging noise by settling up to 90% of pressure peaks that can eventually lead to pipeline breakage. Moreover, it saves up to 10% in pumping energy by temporarily storing it to the flexible inner hose and filler gas. The flexible construction eases system maintenance, leading to reduced downtime costs.
