Description
The Busch SECO Felt Washer (Part# 488000160) is designed for this exact job. It’s not a metal washer. It’s a special ring made of dense, absorbent felt.
This washer acts like a miniature oil sponge. During maintenance, it soaks up clean oil. Then, it is placed in a specific spot inside your pump.
As the pump runs, the felt slowly and steadily releases the oil it holds. This provides a constant trickle of lubrication right where two important parts meet and rotate. This simple, clever system reduces friction where it matters most.
