WARNING
Lock out power to prevent accidental
start-up and physical injury.
1. Lock out power to driver.
2. Make sure coupling hubs are securely
fastened to shafts.
3. Ensure all persons and material are clear of
pump.
4. Unlock driver power.
5. Bump motor and observe rotation. Correct if
required.
Alignment of Flexible Coupling
WARNING
Before beginning any alignment
procedure, make sure the driver power
is locked out. Failure to lockout driver
power will result in serious physical injury.
Alignment of the pump and motor is of extreme
importance for trouble-free mechanical operation.
Straight edge alignment by an experienced
installer proves adequate for most installations. For
disc couplings and applications where it is felt that
alignment to tighter tolerances is desirable, use
dial indicators. Standard dial indicator procedures
would apply.
Alignment procedures must be
followed to prevent unintended
contact of rotating parts. Follow
coupling manufacturer’s installation and
operation procedures.
When installing in a potentially
explosive environment, ensure that the
motor is properly certified.
The coupling used in an ATEX
classified
environment must be
properly certified.
Straight Edge Alignment
1. Check for coupling alignment by laying a
straight edge across both coupling rims at four
points 90 degree apart.
2. Move motor until straight edge rests evenly at
each position. Repeat procedure until correct
alignment is achieved.
3. Install flexible sleeve between the hubs per the
manufacturer’s directions included with the
pump data package.
4. Tighten all motor bolts.
Coupling Guard
WARNING
Never operate a pump without
coupling guard properly installed.
Personal injury will occur if pump is
run without coupling guard.
1. Install coupling guard (See Figure 7) by
wrapping the expanded metal shield (501)
around the motor support and installing the two
guard springs (501L).
