In the fuel injection system of heavy diesel engines, pressure fluctuations occur frequently, caused by the high pressure pumps during the injection process.
These produce pulsations which adversely affect components and, in the worst cases, the entire engine, and can even damage them beyond repair. This results in high maintenance and repair costs.
If unsuitable types of damper or accumulator are selected, the desired effect is often short-lived. In addition to the classic metal bellows accumulator solution, HYDAC has now developed a "RETROFIT SOLUTION" as well. With the tried & tested metal bellows as the separating element, permanent damping is guaranteed.
The compact design and the variable connection options ensure quick replacement and are effective in reducing engine downtime. Using HYDAC metal bellows accumulators therefore saves time and money and reduces pulsations permanently.
Metal Bellows Accumulator advantages
- Metal bellows is fluid-resistant across entire temperature range
- 1:1 replacement whether a repair or in an emergency
- Quick conversion to HYDAC metal bellows accumulator during a service interval
- Simply replaced
