Impeller Removal
 Remove seal bellows and spring assembly (Ref 12).
Note: The seal bellows will be bonded to the shaft sleeve and will require some patience
and caution to remove in order not to damage the seal bellows and cage.
 Place the impeller drive sleeve (Ref 4) between two pieces of wood in a vise. Take care so
as not to damage sleeve.
 Remove the impeller jam nut (Ref 9) from the end of the shaft sleeve. Unthread the
impeller (Ref 10) by turning counterclockwise (left hand).
Inspection
Check all parts for wear. For ease of reassembly, the shaft sleeve should have all nicks and burrs
removed. Replace damaged parts with new parts. Inspect the seal seat and seal cup for grooves;
scuff marks, or other deterioration. If a perfect lapped surface remains on the seal seat, it may be
reused. If the seal cup is in good condition, it may be reused. If the seal seat, cup, washer, or
bellows are damaged or worn, a new seal assembly should be installed (See Models: DB, DC, DF,
DG, DT, DL; under Section 4.2 Pump Maintenance for seal replacement).
Impeller Clearance Adjustment
Impeller face and back clearances are not critical. The impeller must be adjusted axially so that it
does not rub, that is it should be centered in the space between the adaptor frame and housing.
After the pump has been installed on the motor with two cap screws, the impeller can be adjusted
as follows:
 Center the drive clamp assembly (Ref 5) and tighten.
 Loosen the two cap screws holding the pump to the motor (not shown).
 Pull the motor away from the pump and insert the .032” (.813 mm) shims (Ref 12) between
the pump adaptor frame (Ref 5) and the motor. Align the holes in the shims so that
remaining two cap screws can be installed.
 Install the remaining two cap screws and tighten all four.
 Rotate motor slowly by hand to make certain the impeller does not rub the housing or
adaptor frame.
If the impeller still rubs, loosen the drive clamp assembly (Ref 5), remove two of the cap screws
and shims (not shown), loosen the other two cap screws and repeat above procedure.
If the above procedure does not stop the impeller from rubbing, CONSULT THE FACTORY.
