Valisi VPHP In-Line Pulsation Dampeners

Valisi VPHP In-Line Pulsation Dampeners reduce vibrations, pulsations, and hydraulic shocks in the system, whilst increasing the life of the hose and preventing damage in pumps, valves, and process instrumentation. A reinforced rubber hose is mounted inside a metallic, cylindrical pressure vessel; compressed air or nitrogen fills the space between them, allowing the hose to adjust its volume according to the pressure at pump discharge, compensating for any pulsation in the liquid flow.

VPHP Pulsation Dampeners can decrease the pressure fluctuations caused by the operation of the pump by 90%, granting a safer system and environment. VPHP Pulsation Dampeners are available in four sizes and are suitable for models VPH25 to VPH125 (shoe pumps) and N5N to N7N (roller pumps). 

Pulsation dampeners comply with European PED Directive 2014/68/EU. NBR-FDA hoses can be used for food applications.

Key Benefits

  • High Efficiency:

Capable of reducing pressure fluctuations and pulsations by up to 90%.

  • How They Work:

VPHP dampeners feature an internal hose encapsulated within the unit. The space surrounding the hose is pressurized with air or nitrogen. When the pump pushes a pulse of fluid, the hose expands to absorb the excess volume and pressure. During the pump's intake cycle, the air/gas cushion forces the trapped fluid back into the line.

  • Safety and monitoring:

Can be fitted with a NAMUR capacitive sensor for reliable detection of internal hose faults.

  • Material versatility: 

Available in various sizes, ideally suited for Valisi VPH (shoe) and N7N (roller) series pumps.

Typical applications: 

Dosing and metering: Ensures a uniform flow of liquid for precise dosing of chemicals. 
Industry and water treatment: Ideal for pumping abrasive, viscous or corrosive liquids under high pressure. 
Food and pharmaceutical industries: Enables the damage-free pumping of liquids subject to sanitary requirements and sensitive to shear.

Progressive cavity pumps

Today, ASCO POMPE manufactures screw pumps that are used in a variety of industries, from wastewater treatment plants to the wine and food industry. Screw pumps are positive displacement pumps and are designed for pumping various types of liquids: viscous, abrasive, additive liquids, suspensions and dispersions. The valve-less design of the pump, the direct dependence of its performance on the engine speed, and the ability to change the direction of flow of the pumped liquid are undoubtedly the advantages of screw pumps.
