The Pacer P-58-46219.10 is a stainless steel shaft sleeve for the 2 in T Series pump. The sleeve covers the shaft where it passes the seal, so wear and corrosion land on a replaceable part instead of the shaft itself.
T Series pumps are self-priming soft-solids pumps with an oil-lubricated silicon carbide shaft seal, and a worn sleeve can score the seal faces and cause leaks. Replace the sleeve whenever it is grooved or pitted, and refit the seal while the pump is open.
