H. PUMP MAINTENANCE
WARNING
Failure to observe precautions while installing, inspecting, and maintaining the pump can
cause injury to personnel from accidental handling of liquids that may harm skin or
clothing, or fire hazard risks from flammable liquids, or injury from high pressure fluid jets.
DANGER
BEFORE
working on equipment, make sure all power to equipment is disconnected and
locked-out.
H.1 GENERAL COMMENTS
NOTE:
Part number identifiers (IDPs) contained within parenthesis such as (10) refer to the circled
numbers shown on the assembly drawing. See Table 2. Figure 4A and Figure 4B.
H.2 TOOLS REQUIRED
The procedures described in this manual require common mechanics hand tools, a torque wrench,
dial indicator and suitable lifting device (such as) slings, straps, etc.
H.3 NYLOK FASTENER TORQUE PROCEDURE
The required torque stated on the assembly drawing does not include the additional torque required
to install fasteners containing Nylok inserts (pellets, strip, patch, ring collar). The torque required for
the first application is much higher than it is for subsequent applications. To insure the required
preload on a Nylok fastened joint is achieved for each application, the following procedure is
mandatory assembly practice.
Step 1.
Using a suitable torque wrench, install the fasteners in the mating piece until the Nylok insert
is completely engaged. Note the torque required.
Step 2.
Add the torque measured in Step 1 to the torque value called for on the assembly drawing.
Step 3.
Complete by tightening the fastener to the torque value determined in Step 2 above.

DISASSEMBLY PROCEDURES
Note: To service mechanical seal, perform Section I. ONLY.
CAUTION
Fluid leakage from disassembly of pump may make the floor slippery and can cause
personal injury.
NOTE:
The C324AXFX-250/12005 pump incorporate highly finished precision parts that must be
handled carefully to avoid damage to critical machined surfaces. The parts removed should
be tagged for identification and their exact positions in the pump carefully noted so that new
parts, or the same parts, are properly replaced without damage.
I.1 SERVICING THE MECHANICAL SEAL
The mechanical seal supplied is a Chesterton 180 Cartridge type. PP046KNK is Imo Pump’s assigned
part number. If a sealing problem develops, it is recommended the complete cartridge be returned to
the nearest Chesterton repair facility for evaluation and possible rebuild or contact the Imo Pump
Service Department for assistance.
