30 6EM Thru 18GM - 1100 Vertical Turbine Pumps
B. Install the coupling hubs on the driver
shaft and top shaft prior to installing the
driver according to the following
procedure:
NOTE
It is generally most convenient to install
the driver coupling hub on the driver
shaft before hoisting the driver into
position.
Figure B
Style IV Adjustable Coupling
1. Insert the square key into the driver
shaft keyway and slide the driver
coupling hub onto the driver shaft
until the circular keyseat is exposed.
Install the thrust rings. When a
spacer is used, pilot the spacer in to
the driver hub and secure with the
short bolts.
2. Install a dowel pin into the hole
provided in the pump coupling hub.
Drive the pin through the coupling
hub until it protrudes slightly into the
coupling keyway. The purpose of this
pin is to prevent the key from falling
out of the hub until the setscrew has
been secured. Slide pump coupling
half hub over top shaft threads.
3. Align the keyway in the shaft with the
keyway in the coupling hub and insert
the key.
4. Thread the coupling adjusting nut onto
the top line shaft.
5. Using an appropriate hoisting system,
lift the driver over the discharge head
mounting surface and carefully lower
into position. Engage the base over
the register fit of the mounting
surface. Temporarily bolt the driver
down. If an electric motor is used,
now is the time to connect to the
electrical source per manufacturer's
instructions and verify correct
rotation. If a right angle gear is used
proceed to step 4.
DANGER
Make sure the main power source is
locked off before any electrical
connections are made and verify driver
cannot be started. After the start has
been performed, again lock off the
main power source to guard against
accidental starting and electrical
shock.
CAUTION
Oil lubricated drivers and right angle
gears are shipped dry and require an
initial fill of the manufacturer's
recommended lubricant prior to bump-
start.
WARNING
Make sure all loose coupling parts are off
the motor half coupling, and that no part
of one coupling half will contact the other
half during the bump start, otherwise
personal injury could occur.
WARNING
Make sure the protective guard is in place
on the discharge head before the bump
start is done. Do not operate this
machine, even to check rotation, without
protective guards in place.
C. With non-reverse ratchets (if so
equipped) removed or disabled, "bump"
the motor for rotation. Bump start is
generally accomplished on three-phase
motors by engaging and immediately
disengaging the power switch. It is
