DPT Pulsation Dampeners

Pulsations are a common challenge with Peristaltic Pumps, occurring when the shoes release the hose after compression on the discharge side. As the compressed hose returns to its original shape, the volume at the pump’s discharge increases, causing pressure drops along the installations discharge line. This occurrence gives rise to undesirable pulsations, vibrations and hammering within the piping system.

Fortunately, our DPT Pulsation Dampeners have been designed to tackle these pulsations head-on, keeping them to a minimum. These dampeners use a compressed vessel with a reinforced hose filled with compressed air or nitrogen. This is to absorb and mitigate the pulses generated by the Peristaltic Pump. It’s important to note that although these dampeners have been designed for Peristaltic Pumps, they are suitable for additional pump types as well.

The lifetime of the hose in a Peristaltic Pump is significantly extended, ensuring long-term reliability and reducing maintenance costs, By minimising pulsations, the dampeners enhance the overall performance of your installation, promoting smooth and uninterrupted operations. For added convenience, these dampeners can be installed in either a vertical or horizontal position, accommodating the unique requirements of your pumping system.

• Reduced downtime and maintenance costs: by curbing pulsations, these dampeners minimise wear and tear on your system
• Easy to clean: as the inner part of the hose is the only part to come into contact with the fluid being pumped, maintenance procedures and cleaning routines are simplified
• Versatile: while designed for Peristaltic Pumps, these dampeners are also suitable for use with additional pump types
• Certified design: our DPT Pulsation Dampeners comply with rigorous standards set out by the European PED Directive 2014/68/EU
• Superior fluid compatibility: these dampeners can handle abrasive, corrosive and even viscous fluids with particles up to 20% of the inner hose diameter

Dampening Effect:

The dampener installed at the pump outlet (light blue) decreases the flow pulsation hen compared to that without it (shown in dark blue). This results in a proven pulsation reduction by up to 80%!
