Spider Coupling, Leybold, Trivac, Part# 20009358 – vacstellar

Description

This spider coupling is a flexible connector for your Leybold Trivac pump. It connects the electric motor to the pump head. Its special job is to absorb vibrations and small misalignments. This protects both the motor and the pump from damage.The center spider is usually made of a flexible material like polyurethane. Over many years of use, it can wear out or crack. Replacing the coupling is much cheaper than repairing a damaged motor or pump bearing. It’s a smart piece of preventative maintenance.
