This Vane Spring (Part #3836534) is a replacement part made specifically for Pfeiffer UNO 1.5A and DUO 1.5A vacuum pumps . Its job is to provide the necessary tension and support for the vanes inside your pump . This allows the vanes to move freely while maintaining proper contact with the pump’s rotor . If you are rebuilding your pump, you will need four of these springs for a complete repair
