Coupling Insert, Leybold, Trivac, Part# PL20009094 – vacstellar

Description

This Coupling Insert (Part# PL20009094) is the flexible heart of your Leybold Trivac pump’s drive system. It connects the motor to the pump, absorbing vibrations and minor misalignments. Replacing this critical wear part prevents damage, reduces noise, and ensures smooth, reliable power transfer for your D40B, D65B, D40BCS, and D65BCS models. This protects both the motor shaft and the pump shaft from stress. Without it, metal would grind against metal, causing premature wear, noise, and potential failure.
