AODDampeners from Blacoh Fluid Control.

Blacoh’s newly designed AODDampener constructed of 316L stainless steel with a PTFE diaphragm, employs an automatic air control that utilizes the existing compressed air source in an AODD pump system for charging. According to Blacoh engineer David McComb, with this single configuration Blacoh’s new AODDampener is compatible with over 80% of the existing AODD pump applications in the US.

Mr. McComb explained that their new AODDampener’s unique automatic air control works with AODD systems where fluid pressures vary substantially on a regular basis. “With the automatic air control, you don’t have to adjust the dampener’s charge at pump startup or when there is a change in system pressure. Just turn on the pump and the dampener adjusts itself.”

Another benefit of the dampener’s automatic air control is that it doesn’t require air unless the average line pressure in the system changes. Compressed air is costly, so Blacoh designed the AODDampener to work with minimal air consumption. As the fluid line pressure increases, the air charge in the dampener is increased to match it. When the line pressure drops, the dampener bleeds off charge, keeping the dampener optimally charged for maximum dampening effect.
