Metal Bellows

Metal Bellows Accumulators are a unique type of dampener that use a metal bellows separation element between the fluid and gas side of the metal bellows accumulator. This makes the accumulator virtually gas-tight and maintenance free. By replacing the traditional elastomer element or seals, the metal bellows is fluid resistant in temperature ranges of -85 °F to +320 °F. These special features lend themselves to dampening applications in fuel injection systems in heavy diesel engines in the mobile, marine & industrial markets. The SM50P series has a fluid port diverter feature to maximize its dampening capability. The SM50 series has a threaded fluid connection to allow for easy retrofit of standard accumulators in existing systems.
