A vibration dampener is a box containing gas (usually dry nitrogen). ; Its main function is to prevent oil from entering the circuit. These spacers are made of two materials: rubber (NBR, EPDM, FPM, butyl, silicone, etc.) or thermoplastic (mostly PTFE), but can also be made of stainless steel There is metal
In every pulsation dampener there is a separator element between the gas it is charged with and the liquid of the circuit; its basic function being to avoid the leaking of the gas into the circuit. This separator element is basically made of two kinds of materials: Rubber (NBR, EPDM, FPM, butyl, silicone, etc…) or a thermoplastic material (normally PTFE); although it can also be made in stainless steel
The damper when used when there are rubber distribution elements is called a bladder damper . If the material is PTFE, we are talking about membranes and dampers, depending on the product. Special design shock absorber. All vibration dampers are designed to ASME VIII Div. ) changes in customer needs.
The bellows can also be made of stainless steel, to suit special dampeners designed for working with high temperature liquids.
Choosing between different types of dampener depends on characteristics of the circuit like working pressure, temperature and chemical compatibility between the liquid and the material of the separator.
All our pulsation dampeners are made according to the ASME VIII Div.1 & 8 codes requirements.
We can supply all of our dampeners with different circuit connection gauges as well as fitted with whatever flange, either screwed on, welded or integrated, to suit the customer’s needs.
