7. Separate the volute from the pump head being careful not to damage the
clearance rings, impeller or mechanical seal. If necessary, tap the volute
free using a soft hammer, i.e., rawhide, rubber, etc. Support the weight of
the volute as it is heavy and bulky.
IMPORTANT !
DO NOT DAMAGE THE BRASS CLEARANCE RINGS OR IMPELLER AS YOU SEPA-
RATE THE VOLUTE (PUMP BODY) FROM THE PUMP HEAD.
8. Inspect the rear clearance ring, located in the volute, for wear and replace
accordingly - see heading “Clearance Rings, Impeller Measurement” on
page 95.
9. To remove the clearance ring, use a hammer and chisel to collapse the ring
in the housing. Do not mar the sealing surfaces of the housing.
WARNING !
BE SURE TO WEAR SAFETY GLASSES WHEN REMOVING AND/OR INSTALLING
FORCE (PRESS) FITTED PARTS. FAILURE TO COMPLY MAY RESULT IN SERI-
OUS EYE INJURY.
Note: Removing the clearance ring renders it inoperative. It must be replaced. A
usual good practice, if one ring requires replacement the other should be re-placed as
well. Also verify the impeller clearance - see heading “Clearance Rings, Impeller
Measurement” on page 95.
