Rotary Vane Pumps and Gas Ballast Explained | BVV

A gas ballast is a passageway that leads into the compression side of the crescent cavity allowing for small airflow. The amount of airflow allowed is controlled through a cap located on the exterior of the pump. Fig.3: Gas Ballast Diagram Using a Gas Ballast. Some pumps have three positions for the gas ballast: closed, medium flow, and high flow.

FAQ Pumps - JB Industries, Inc.

On the initial pull of vacuum on a system, the gas ballast is open allowing the initial volume of air in the system to bypass the oil so as to not contaminate the oil immediately. When the pump starts to quiet down, close the gas ballast and the pump will start reducing atmospheric pressure in the system to boil the moisture and non-condensables.

Jan 10, 2017 · In addition to rotary-vane pumps, it is also used in scroll pumps and piston pumps, to name a few. Wolfgang Gaede developed the gas ballast principle in 1935, which was first applied to rotary-vane pumps. The ballast gas is drawn into the pump chamber through a one-way valve (aka gas ballast valve) located on the pump.
