MAINTENANCE

It's necessary to disassemble parts of the pump for cleaning and santizing. For C-Series pumps equipped with
the "Groove-In-Shaft" design (types D, DG, or F seals only), it is not necessary to disassemble if used in a
Clean-In-Place installation.
The extent of disassembly will depend on the application, and the type of seal used in your pump. To disassem-
ble, disconnect the inlet and outlet lines. Remove seal guard assembly with a wrench of appropriate size. Turn
the wing nuts on the clamp assembly until tension on the clamp saddle is relieved. Open the saddle and remove
the casing.
Push back on the impeller and center the retainer in the stub shaft. Slide the impeller forward and remove it.
Do not try to remove retainer before removing impeller as this will cause damage to the retainer, shaft and
impeller.
1. Rotate the backplate until the backplate pins clear the pins in the adapter and remove the backplate
2. Remove the casing gasket.
Note: Protect the sealing surface of the backplate against nicks and scratches while removing,
cleaning and ressembling.
3. Remove the carbon seal, o-ring seal- seal cup,and spring.
DG/FG CLAMPED IN SEAT
1.Remove four bolt/screws from backplate. Inspect DG seat insert, gland ring and gaskets for damage or wear,
and replace as required.
Note: #80P outboard and #80R inboard gaskets are NOT INTERCHANGEABLE #80R (thicker) gasket MUST be
inboard-between backplate and seal seat. Care must be taken to protect the sealing face of the backplate for D
and F seals and the seal seat for DG seals from nicks and scratches.
2. Remove the carbon seal and o-ring seal. Examine and replace as necessary.
