EBARA Fluid Handling 6
PREINSTALLATION INSPECTION POSITIONING PUMP
The pump assembly was inspected and tested at
the factory. Before installation, inspect the pump
for damage which may have occurred during
shipment. Check as follows:
a. Inspect the pump for cracks, dents,
damaged threads, and other obvious
damage.
b. Check for and tighten loose attaching
fasteners. Since gaskets tend to shrink
after drying, check for loose hardware at
mating surfaces.
c. Carefully read all warnings and cautions
contained in this manual or affixed to the
pump, and perform all duties indicated.
Note the direction of rotation indicated on
the pump. Check that the pump shaft
rotates counterclockwise when facing the
back cover plate assembly/impeller end of
the pump.
Lifting
Use lifting equipment with a capacity of at least
2500 pounds (1134 Kg). This pump weighs
approximately
500 pounds (222 Kg) , not including
the weight of accessories and base. Customer
installed equipment such as suction and discharge
piping must be removed before attempting to lift.
CAUTION!
The pump assembly can be seriously
damaged if the cables or chains used to lift
and move the unit is improperly wrapped
around the pump.
CAUTION!
Only operate this pump in the direction
indicate 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.
Refer to LUBRICATION in the
MAINTENANCE AND REPAIR section of
this manual and perform 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 exceeded their maximum shelf life.
These must be inspected or replaced to
ensure maximum pump service.
If the maximum shelf life has been exceeded,
or if anything appears to be abnormal, contact
your EBARA distributor or the factory to
determine the repair or updating policy. Do not
put the pump into service until appropriate
action has been taken.
Mounting
Locate the pump in an accessible place as close as
practical to the liquid being pumped. Level mounting
is essential for proper operation.
The pump may have to be supported or shimmed to
provide for level operation or to eliminate vibration.
Clearance
When positioning the pump, allow a minimum
clearance of 31 inches (800 mm) in front of the back
cover to permit removal of the cover and easy
access to the pump interior.
SUCTION AND DISCHARGE PIPING
Pump performance is adversely affected by
increase suction lift, discharge elevation, and friction
losses. See the performance curve and operating
range shown on Page 21 to be sure your overall
application allows 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 liquid being pumped.
