Air vessels

With traditional air vessels, the gas cushion is held directly above the conveyed fluid. Under peak pressures and/ or excessive flow, this cushion is compressed above the fluid level and released during the suction stroke of the pump. The fluid is then displaced into the discharge pipe and minimises pulsations accordingly.

Since there is no separation between gas cushion and medium, air vessels are mostly only used for low pressure applications or at the suction side.
