The coupling connects these two parts together. It transfers the power from the motor to the pump. But it does something else too. The coupling is flexible. It has a soft rubber-like spider shape in the middle. This flexibility absorbs shocks and vibrations. It also allows for small misalignments between the motor and the pump. This protects both the motor and the pump from damage. The elastomer material is designed to dampen twisting forces .
We kept this simple. This Part# 90220010600 fits many Becker U Series pumps . Here is the full list:
U4.70 Series: U4.70, U4.70D, U4.70E, U4.70F, U4.70G, U4.70H
