Refer to Table 2-1 for service. Perform Items 1, 2 and 3; check for leaks and take current and voltage readings.
Electrical components contain high voltages that can cause severe
injury or death. Before servicing, adjusting or replacing electrical or
mechanical components, disconnect the power supply to the electric
motor and tag, "Out of Service, Do Not Operate ."
Unbolt piping at suction and discharge flanges to see if the piping springs
away from the flanges, thereby indicating a strain on the casings.
When pump is replaced, use shims under the pump/motor feet to bring pump
into alignment with the suction and discharge lines.
Open discharge gauge tap (10), remove casing drain plug (12), drain pump,
and replace drain plug (12).
From electric motor conduit box (1), remove four cover machine screws (2),
cover (3), and gasket (4). Tag and disconnect electric cables from motor.
From pump suction (11) and discharge (9) piping flanges, remove hex machine
bolts (15), lockwashers (6), nuts (7), and gaskets (8). Discard gaskets.
Using the lifting sling, spring back and secure suction and discharge
piping enough to provide clearance between piping and pump flanges.
Using the lifting sling, rig pump/motor assembly for removal.
Remove eight machine bolts (13), hex nuts (15), and flat washers (14).
Remove pump/motor assembly from foundation.
Using the lifting sling, rig new pump/motor assembly into place.
Align pump/motor assembly to foundation. Install eight foundation machine
bolts (13), hex nuts (15), and flat washers (14).
