A lock washer is not a flat, ordinary washer. It has a special shape. Some are split. Some have teeth. That shape gives it one job: to stop screws from spinning loose.
You put it under a screw head or a nut. When you tighten the screw, the lock washer pushes back. It creates tension. That tension keeps the screw from backing out .
This one lock washer fits many pumps. It works on two brands: Ebara and Busch.
Here are the exact models:
Ebara AA Series:
AA10
AA20
AA70W
AA100WN
Busch Panda Series:
WV250B
WV250C
WV500B
WV500C
If you own any of these pumps, this is the right washer for you
