D-2) Starting:
After completion of procedures outlined in Section C and D-1,
the pump is then ready for operation. Start pump by applying
power to motor as outlined in the Motor Instructions.
D-3) Shutdown:
Operation may be discontinued by disconnecting electric pow-
er. When the pump has been operating in freezing weather or
in liquid containing a considerable amount of solids, it is advis-
able to drain the pump body by removing drain plug (26) and
fl ushing the solids out of the body. Replace the drain plug.
D-4) Restart:
At each subsequent start, particularly if the pump has been
drained, the priming liquid level should be checked since
the pump is self-priming only when the body is full of liquid.
SECTION E: PUMP SERVICE AND REPAIR:
E-1) Check Valve Service:
To clean out or repair check valve, disconnect suction piping.
Remove cap screws (24) and suction
fl ange (23).
DO NOT
PRY ON FLANGE
but rather bump off with a block of wood
and a hammer. Pull off gasket (22C) together with weights
(22A) and (22B), round head screw (22E) and lockwasher
(22D). Examine and replace any parts showing wear or dam-
age.
When replacing gasket and weight assembly onto pump body
make sure that HINGE section of gasket (22C) is at TOP and
that LARGE weight is on PUMP SIDE of gasket.
E-2) Body, Volute and Impeller Service:
To clean out or repair the body (18), volute (15) or impeller
(12), disconnect suction and discharge piping. Remove hex
nuts (21) and lockwashers (20) and pull body (18) from in-
termediate coupling (2). This will expose O-ring (4), impeller
(12), impeller locking screw (13), volute (15) and volute gasket
(17). Examine and replace any part showing undue wear or
damage.
When impeller (12) needs replaced, pull volute (15) from
intermediate coupling (2), remove set screw (13 on 3CCE
- 5CCE) or cap screws (13) and washers (14) on 10CCE
- 25CCEs, and unscrew the impeller from the motor shaft.
The impeller is screwed onto the shaft with right hand
thread and to break loose use a block of wood against a
vane and strike with a hammer. At reassembly, be sure to
use the required number of shims (10) and (11) to result
in an impeller-to-volute clearance of not more than .015”.
E-3) Shaft Seal Service:
To examine or replace shaft seal, remove body (18) and
impeller (12) as outlined in Paragraph E-2. Remove im-
peller shims (10) and (11). Remove rotating member of
shaft seal (9) from motor shaft. All of the components of
the shaft seal are now exposed for examination. If any
part shows wear or damage, replace entire shaft seal as-
sembly. When stationary member needs replacing, pry
used stationary member from intermediate coupling (2).
CAUTION! - handle seal parts with extreme care.
DO NOT scratch or mar lapped faces.
Lightly oil ring and press stationary member over motor shaft
and into intermediate coupling (2). Lightly oil motor shaft and
inner surface of bellows of rotating member. With lapped
surface facing intermediate coupling, slide rotating member
onto shaft until lapped faces of rotating member and station-
ary member are together. Reassemble remainder of pump.
E-4) Motor Service:
To remove or replace motor (1), disassemble pump as
outlined in Paragraphs E-2 and E-3.
Remove cap screws (5), lockwashers (6) to remove motor (1),
and base (7) (On 3CCE - 5CCE’s). To remove motor (1) from
base (7) on 10CCE - 25CCE’s, remove cap screws (28) on
hex nuts (27).
SECTION: F REPLACEMENT PARTS
F-1 ORDERING REPLACEMENT PARTS:
When ordering replacement parts, ALWAYS furnish the fol-
lowing information:
1. Pump serial number and date code. (F-4)
2. Pump model number. (F-3)
3. Pump part number. (F-2)
4. Part description.
5. Item part number.
6. Quantity required.
7. Shipping instructions.
8. Billing instructions.
F-2 PART NUMBER:
The part number consists of a six (6) digit number, which
appears in the catalog. A one or two letter suf
fi x may follow
this number to designate the design con fi guration. This
number is used for ordering and obtaining information.
F-3 MODEL NUMBER:
This designation consists of numbers and letters which
represent the discharge size, series horsepower, motor
phase and voltage, speed and pump design. This number
is used for ordering and obtaining information.
F-4 SERIAL NUMBER:
The serial number block will consist of a six digit number,
which is speci
fi c to each pump and may be preceded by a al-
pha character, which indicates the plant location. This number
will also be suf
fi xed with a four digit number, which indicates
the date the unit was built (Date Code). EXAMPLE: A012345
0490.
Reference the six digit portion (Serial Number) of this number
when referring to the product.
