This 2nd Stage Vane (Part #230103) is a replacement part made specifically for the high-performance Pfeiffer DUO 12M two-stage rotary vane pump. It is designed for use in the second stage (high vacuum stage) of this reliable pump, which can achieve an ultimate pressure down to 2 × 10⁻¹ Pa (approx. 1.5 × 10⁻³ Torr) . Vanes are the heart of any rotary vane pump, and this component is critical for achieving the pump’s maximum vacuum rating.

Pfeiffer DUO 12M, 2nd Stage Vane - Part # 230103

Pfeiffer DUO 12M, 2nd Stage Vane - Part # 230103
This is the 2nd Stage Vane (Part #230103) .
As the rotor spins, these vanes are pushed outward by springs and centrifugal force. They slide in and out of their slots, constantly maintaining perfect contact with the pump’s cylinder wall. This action traps a volume of gas and then compresses it, pushing it out of the exhaust. This is the fundamental process that creates and maintains your vacuum.
Without vanes in good condition, your pump simply cannot perform.
