Abstract
A seal configuration described herein is a seal that less likely to clog, requires low maintenance, and more cost effective than conventional designs. For example, a seal configuration for a shaft sleeve has a unitary piece having at least two curved lip elements extending radially inwardly from the unitary piece to the shaft sleeve and at least two spacers extending radially inwardly from the unitary piece to substantially near the shaft sleeve. The unitary piece has an alternating arrangement of lip elements and spacers. The shaft sleeve can be made of silicon carbide.
