10 6EM Thru 18GM - 1100 Vertical Turbine Pumps
Discharge Heads
Discharge heads perform multiple functions:
direct the pump flow from the pump column
to the discharge piping system, provide a
method for sealing the line shaft, provide a
base from which the pump is suspended,
and provide a mounting surface for the
driver.
Surface discharge heads incorporate both
the discharge elbow and driver pedestal in
one piece. An underground discharge
elbow can also be provided in which case a
separate driver pedestal is provided. The
bottom surface of the discharge head or
pedestal is machined when furnished with a
sole plate.
Drivers
A variety of driver sizes and types can be
supplied based on the specific job
requirements. Drivers may be either vertical
hollow or vertical solid shaft motors or right
angle gears connected to horizontal shaft
drivers.
Normally a vertical hollow shaft driver is
used. In this configuration, the line shaft
passes through the driver, positioned with
an adjusting nut to accommodate impeller
adjustment, and is connected to the top of
the driver by a keyed drive hub or coupling.
Solid shaft drivers require special adjustable
couplings in order to attach to the pump
shaft and to accommodate impeller
adjustment. Refer to your submittal
package for your specific pump driver
configuration.
