28 6EM Thru 18GM - 1100 Vertical Turbine Pumps
out of the hub until the setscrew has
been secured. Slide pump coupling
half hub over top shaft threads.
C. Align the keyway in the shaft with the
keyway in the coupling hub and insert
the key.
D. Thread the coupling adjusting nut
onto the top line shaft.
E. 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 can not 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.
3. 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
seldom necessary to engage the power
source for more than one second to
determine motor rotation.
Note the direction of motor rotation. If the
motor rotates counter clockwise as
viewed from the top, the rotation is to
correct and installation may proceed. If
the motor rotates clockwise as viewed
from the top, reverse any two of the
three power leads and motor rotation will
be reversed.
CAUTION
Operation of the pump in a clockwise (as
viewed from the top) direction will cause
the line shaft couplings to unthread,
causing serious damage to the pump.
4. Impeller adjustment is required to
achieve the preferred running position of
the impeller within the pump bowl. Also,
the impeller must not rub on the bowl
seat.
