Dongkai is a leading China Bladder-Operated Vibration Absorber manufacturers, suppliers and exporter. The Bladder-Operated Vibration Absorber could be considered as the most traditional and widespread dampener, since it offers a great performance and is manufactured in a very wide range of sizes and building materials. Competitive in price, it is also easy to install. It is specially indicated for clean liquids without suspended solids and of low viscosity. It is manually adjustable and usually installed together with back pressure valves to guarantee the correct pressurisation of the air chamber in relation to the working pressure of the pump, being this assembly very common in diaphragm or piston metering pumps.
1. Product Introduction of Bladder-Operated Vibration Absorber
Dongkai is Bladder-Operated Vibration Absorber manufacturers and suppliers in China who can wholesale Bladder-Operated Vibration Absorber.

Standard bladder materials are supplied in Nitrile (Buna-N), EPDM, Viton (B), Viton (GF), Peroxide-Cured EPDM, Neoprene, Epichlorohydrin, Hypalon and Butyl rubber.
Designs are available in pressure ratings to as high as 1,380 BarG (20,000 PSIG).
Screwed or flanged connections and a choice of single, twin or multiple porting is available. Thousands of these dampers installed worldwide testify to the effectiveness of this simple design concept in smoothing the flow from reciprocating pumps.
2.Product Parameter (Specification) of Bladder-Operated Vibration Absorber
Bladder-type Damper Advantages
High level of efficiency.
Can be manufactured in various materials.
Competitive pricing.
Large variety of models and sizes.
Excessive adjustment of working pressure limits efficiency, but does not generate other problems.
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.
