Leybold Coupling Insert, Part# 20009095

Leybold Trivac pump, the motor spins the pump. But the motor and pump are two separate units. They are connected by a coupling. The coupling has three main parts. There is a hub on the motor shaft. There is another hub on the pump shaft. And between them sits the coupling insert .

The insert is the soft, flexible piece in the middle. Some people call it a “spider” because of its shape. The insert is the most important part of the coupling. It is also the part that wears out first. The insert is made of a flexible material. It flexes every time the pump spins. Over time, that flexing causes wear. This coupling insert (Part #20009095) is the flexible center piece that connects the motor shaft to the pump shaft in Leybold Trivac pumps. The insert transmits torque and power between the two shafts. It also absorbs shocks and vibrations. This helps protect both the motor and the pump from damage. A direct replacement that keeps your pump running smoothly .
