NOTE:
If the rotating assembly has been installed in the pump casing, this
clearance may be measured by reaching through the priming port with a feeler
gauge.
NOTE:
Proceed with Rotating Assembly Installation before installing the impeller
cap screw and washer (10 and 12). The rotating assembly must be installed in the
pump casing in order to torque the impeller cap screw.
After the rotating assembly is installed in the pump casing, coat the threads of the
impeller cap screw (10) with
Threadlocker or equivalent compound, and install the
impeller washer (12) and cap screw; torque the cap screw to 12,4 m.kg.
Rotating Assembly Installation
(Figure 11, Page 23)
NOTE:
If the pump has been completely disassembled, it is recommended that
the suction check valve and back cover assembly be reinstalled at this point.
The back cover assembly must be in place to adjust the impeller face clearance.
Install the bearing housing and seal plate O-rings (27 and 28) and lubricate them with
light grease. Ease the rotating assembly into the pump casing using the installation
tool.
Be careful not to damage the O-rings.
Install the four screw sets of rotating assembly adjusting screw (15) using the same
thickness as previously removed. Secure the rotating assembly to the pump casing
with the hardware (13 and 14). Do not fully tighten the cap screw until the back cover
has been set.
A clearance of 0,25 to 0,51mm between the impeller and the wear plate is also
recommended for maximum pump efficiency. This clearance can be obtained by adjust
an equal of screw from each rotating assembly screw set until the impeller scrapes
against the wear plate when the shaft is turned. After the impeller scrapes, adjust
approximately 0,4mm of clearance with the screw set.
NOTE:
An alternate method of adjusting this clearance is to reach through the
suction port with a feeler gauge and measure the gap. Adjust rotating assembly
screw accordingly.
Suction Check Valve Installation
(Figure 10, Page 21)
Inspect the check valve assembly (11), and replace it if badly worn.
NOTE:
The check valve assembly must be replaced as a complete unit.
Individual parts are not sold separately.
Reach through the back cover opening with the check valve (11), and position the
check valve adaptor in the mounting slot in the suction flange (3). Align the adaptor with
the flange hole, and secure the assembly with the check valve pin (32).
NOTE:
If the suction or discharge flanges were removed, replace the respective
gaskets, apply ‘Loctite No.3 Aviation Gasket Sealant’ or equivalent compound to
the mating surfaces, and secure them to the pump casing with the attaching
hardware
