Vane, 1st Stage - GX, Galileo, Varian - Agilent, Part# 230055G

Part # 230055G 1st Stage Vane compatible with Galileo D08 / D12 and Varian/Agilent DS202 / DS302

The first-stage vane in a rotary vane vacuum pump, also known as the high-vacuum stage, creates an initial level of vacuum. During this stage, the gas is drawn into the pump, and the pressure inside the chamber decreases. The gas discharged from the first stage then flows into subsequent stages for further compression, resulting in even lower vacuum levels.

The vanes in a rotary vane vacuum pump play a critical role in its operation. Over time, they can wear out due to friction, heat, and chemical exposure. Regularly inspect the vanes for signs of wear, damage, or deterioration. The frequency of inspection depends on factors such as pump usage, operating conditions, and the quality of the vanes. If you notice a decline in pump performance (e.g., decreased vacuum level or slower pumping speed), it might be time to check the vanes. Some manufacturers recommend replacing vanes after a certain number of operating hours (e.g., every 1,000 hours). If you observe significant wear or damage during inspections, replace the vanes promptly. It’s better to replace vanes earlier than risk pump failure due to worn-out vanes. Follow the manufacturer’s recommendations regarding material (e.g., carbon, graphite, or other suitable materials). For proper installation, follow the pump’s service manual or guidelines provided by the manufacturer. Remember that timely vane replacement helps maintain pump efficiency, extends the pump’s lifespan, and ensures reliable vacuum performance.
