Edwards Coupling Element, Part# 21071033
The motor has one metal hub. The pump has another metal hub. The Coupling Element is the rubber star-shaped (spider) piece that sits between them .
Think of it like the shock absorber for your pump’s drive train.
It transfers the spinning force from the motor to the pump.
It absorbs the sudden jolts when the motor starts and stops.
It allows for tiny misalignments without damaging the shafts or bearings.
