6EM Thru 18GM - 1100 Vertical Turbine Pumps 27
VERTICAL SOLID SHAFT DRIVERS
General
Solid shaft drivers have a vertical main shaft
projecting from the bottom of the driver
base. The shaft projection has a vertical
keyway to transmit torque and an annual
groove to suspend the pump shaft/impeller
assembly. Solid shaft drivers require the
use of rigid adjustable couplings to facilitate
pump impeller adjustment.
Register fits on the bottom of the driver base
and on the top of the discharge head (motor
pedestal) will facilitate approximate driver
positioning. The fits are generally loose
enough to accommodate the additional
movement required for precision alignment.
After precision alignment is achieved, the
driver is permanently held in position by the
clamping force of the mounting bolts.
Doweling or pinning of the driver is not
required, but may be implemented at the
owner's option.

Style II Coupling
CAUTION
Before installing the driver, read and
understand the driver manufacturer's
instruction manual.
DANGER
Electric motors must be installed and
operated only by qualified, trained
electrical technicians. Consult the motor
manufacturer or the motor manual to
assure that all installation and operation
safety procedures are fully understood
and implemented. Always lock out all
controls and/or power supplies before
installing or servicing.
1. Check both driver and pump shafts for
burrs or dirt, cleaning as necessary.
Also check the coupling parts for burrs
and dirt, cleaning as required. If force is
required to position the couplings on the
shafts, non-metallic dead blow hammers
should be used to prevent damage to the
machined surfaces.
2. 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.
A. 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.
B. 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
