Gorman-Rupp Pumps T10A60S-B /FM,/WW - Manual (Page 9)

OM-05291 SUPER T SERIES
PAGE B - 2 INSTALLATION
Check that the pump shaft rotates counter­
clockwise when facing the impeller.
Only operate this pump in the direction in­
dicated by the arrow on the pump body
and on the accompanying decal. Refer to
Rotation in OPERATION, Section C.
d. Check levels and lubricate as necessary. Re­
fer to LUBRICATION in the MAINTENANCE
AND REPAIR section of this manual and per­
form duties as instructed.
e. If the pump and power source have been
stored for more than 12 months, some of the
components or lubricants may have ex­
ceeded their maximum shelf life. These must
be inspected or replaced to ensure maxi­
mum pump service.
If the maximum shelf life has been exceeded, or if
anything appears to be abnormal, contact your
Gorman‐Rupp distributor or the factory to deter­
mine the repair or updating policy. Do not put the
pump into service until appropriate action has
been taken.
POSITIONING PUMP
Lifting
Pump unit weights will vary depending on the
mounting and drive provided. Check the shipping
tag on the unit packaging for the actual weight, and
use lifting equipment with appropriate capacity.
Drain the pump and remove all customer‐installed
equipment such as suction and discharge hoses
or piping before attempting to lift existing, installed
units.
Make sure that hoists and other lifting equipment
are of sufficient capacity to safely handle the pump
assembly. If chains and cables are used, make cer­
tain that they are positioned so that they will not
damage the pump, and so that the load will be bal­
anced.
The pump assembly can be seriously
damaged if the cables or chains used to lift
and move the unit are improperly wrapped
around the pump.
Mounting
Locate the pump in an accessible place as close as
practical to the liquid being pumped. Level mount­
ing is essential for proper operation.
The pump may have to be supported or shimmed
to provide for level operation or to eliminate vibra­
tion.
SUCTION AND DISCHARGE PIPING
Pump performance is adversely effected by in­
creased suction lift, discharge elevation, and fric­
tion losses. See the performance curve and oper­
ating range shown on Page E‐1 to be sure your
overall application allows the pump to operate
within the safe operation range.
Materials
Either pipe or hose maybe used for suction and
discharge lines; however, the materials must be
compatible with the liquid being pumped. If hose is
used in suction lines, it must be the rigid‐wall, rein­
forced type to prevent collapse under suction. Us­
ing piping couplings in suction lines is not recom­
mended.
Line Configuration
Keep suction and discharge lines as straight as
possible to minimize friction losses. Make mini­
mum use of elbows and fittings, which substan­
tially increase friction loss. If elbows are necessary,
use the long‐radius type to minimize friction loss.
Connections to Pump
Before tightening a connecting flange, align it ex­
actly with the pump port. Never pull a pipe line into
place by tightening the flange bolts and/or cou­
plings.
