Pfeiffer Vane, 2nd Stage – GX, Part# 230072G

This is the 2nd Stage Vane (Part #230072G) .

Think of it like a piston in an engine, but instead of moving up and down, it slides in and out. As the rotor spins, the vane is pushed outward by springs and centrifugal force. It glides along the inside of the pump’s cylinder, trapping gas and pushing it out of the pump.

GX material is a special composite chosen for its excellent properties in vacuum pump applications . It offers:

• Thermal stability: It holds its shape and properties even at higher temperatures.

• Corrosion resistance: It stands up to many chemicals and corrosive gases.

This means your replacement vanes will last longer and perform better, even in demanding conditions.
