Rotary Vane Pumps and Gas Ballast Explained | BVV

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.

The use of gas ballast in rotary vane vacuum pumps- Vacuum .

The ballast valve can accelerate the extraction of steam without polluting the oil. If the rotary vacuum pump only pumping permanent gas, the gas does not liquefy due to the increase in pressure, so there is no deterioration of the pump oil. However, if the pump is used to vacuum dry or pumping humid air, the gas will have not only permanent gas but also Water vapor, if this portion of water .
