Vane, GX, 1st Stage, Pfeiffer DUO120A - Part# 230092

Vane, GX, 1st Stage, Pfeiffer DUO120A - Part# 230092
These are flat, rectangular pieces that slide in and out as the pump spins. They need to stay pressed against the cylinder wall to create a seal and generate vacuum pressure.
This is the 1st Stage Vane (Part #230092) .
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.
