INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
22 SUMMIT PUMP MODEL CCFM GENERAL PURPOSE
11.1 LIQUID END
1. Close the suction valve. Remove pipe plug (01B) in lower section of casing (01 to drain fluid
from casing (01) and piping. Ensure power to driving equipment is locked out and
mechanically disconnected from pump shaft (06). Close isolating discharge valve and remove
attached piping once the fluid is drained.
2. Remove any seal flush lines either from the casing (01) or from external sources.
3. Remove casing bolts (01A) from casing (01). Be careful when removing the final bolt (01A)
to keep casing (01) from falling onto the impeller (02). If needed, use a rubber mallet or dead
blow hammer and in multiple places tap off the casing (01) from the adaptor (71).
Note: 6x8-12G has a case support (53) which is secured by two casing bolts (01A). Before
removing the case support (53), support the casing (01) by means of lifting straps or adding
support under the casing (01).
4. Remove the casing gasket (73A). Replace upon reassembly.
5. If replacing the casing ring (07) press out of the casing (01) using a hydraulic press.
6. To remove the impeller bolt (26), keep impeller (02) and shaft (06) from rotating while
unthreading the impeller bolt (26) with a socket wrench. A soft bar in between the impeller
vanes used as a lever will work but take caution as not to damage the soft bronze or stainless
materials of the impeller (02). An impact used on the impeller bolt (26) is not recommended
as it will shorten the life of the bearings in the driving equipment.
Do not use impact wrench to remove
impeller bolt (26). This will shorten the life of
the bearings.
7. Once the impeller bolt (26) is unthreaded, remove the impeller washer (24A) for cast
iron/bronze constructed pumps or for FM1 & CC1 stainless construction remove the impeller
bolt gasket (26A).
8. Slide the impeller (02) off the shaft (06). Remove impeller key (32).
