INSTALLATION
(see
LUBRICATION
in the
MAINTENANCE AND
REPAIR MANUAL
). An additional quart (0,9 liter)
of oil is provided to “top off” the oil level in the pump
motor cavity, if so required. If the oil level is abnor
mally low, determine the cause before putting the
pump into service.
Due to differences in pump design, the quantity of
oil and manner in which oil is to be added to the
seal cavity varies between pump models. Refer to
Table B‐2 for oil capacities and positions for filling
the seal cavity in each pump. Motor cavities requir
ing lubrication should always be positioned verti
cally for filling. Refer to
LUBRICATION
, Section C
for lubrication specifications and intervals.

Pump Dimensions
For the approximate physical dimensions of your
pump, refer to the pump specification data sheet
or contact your Gorman‐Rupp distributor or the
Gorman‐Rupp Company.
When installing or servicing the pump
or controls, follow all requirements for
the installation of wiring or electrical
equipment as outlined in the National
Electric Code. Follow all safety require
ments. Failure to observe these require
ments could result in injury or death to
personnel.
Do not
allow the free end of the power
cable to enter the liquid being pumped.
The free end of the cable
must
be kept dry
to prevent liquid from wicking through the
cable and into the motor.
NOTE
Refer to the performance curve in the Parts List
Manual
when determining the most efficient piping
installation.
