Paper, plastic, bronze, or rubber?

One of these materials isn't even an option.

A pump set consists of bowls, impellers, bushings, and shaft. The bearings hold the impeller within the bowl so it doesn’t vibrate. Vibration can cause cavitation, the creation of an air bubble that may become pressurized and explode. By minimizing potentially catastrophic damage, effective bowl bearings extend pump life and lower maintenance requirements.

Line shaft bushings occur at spaced intervals within the pipe column. They keep the pump’s drive shaft from “whipping,” or moving erratically rather than rotating. Effective line shaft bearings ensure the pump operates effectively and isn’t exposed to unnecessary stress that may cause damage.
