Conventional diaphragm pulsation dampener
Characteristics of the conventional diaphragm pulsation dampener
The diaphragm pulsation dampener belongs to a range of conventionally designed dampeners which offers a somewhat lower performance than bladder type pulsation dampeners, but is manufactured in an extremely wide range of sizes and building materials. These are more suitable than the bladder type when the liquids contain suspended solids or are of a certain viscosity.
This Flexodamp pulsation dampener is manually adjustable and is usually installed in conjunction with back pressure valves to ensure the correct pressurisation of the air chamber in relation to the working pressure of the pump.
Advantages
- Similar assembly as conventional bladder.
- Can be manufactured in various materials.
- Improved possibility of use with liquids with suspended solids or viscous liquids with respect to bladder dampeners.
Disadvantages
- Manual adjustment of working pressure.
- Usually requires the use of other accessories such as back-pressure valves to avoid pressure variations in the system-
- Excessive adjustment of working pressure limits efficiency, but does not generate other problems.
- Average level of efficiency.
