Pump Reassembly/Seal Replacement

the impeller with your thumbs and wipe off the ceramic and carbon faces with a clean cloth.

Shaft Seal Replacement
The Shaft Seal consists primarily of two parts, a rotating member and a ceramic seal. The pump
requires little or no service other than reasonable care, however, a shaft seal may occasionally
become damaged and must be replaced.
Note:
The polished and lapped faces of the seal could be damaged if not handled with care.
