INSTALLATION
AFTER CAREFUL PRELIMINARY INSPECTION, YOU MAY
PROCEED WITH THE INSTALLATION OF THE PUMP INTO YOUR
SYSTEM.
1. LOWER THE PUMP INTO SYSTEM.
2. MAKE SURE THE MOTOR BASE AND CASING IS SETTING
FIRMLY ON THE SUPPORT. (IT MAY BE NECESSARY TO USE
METAL SHIMS TO LEVEL.)
3. SECURE THE MOTOR BASE AND CASING BY USING HOLD-
DOWN SCREWS. AGAIN, CARE MUST BE TAKEN TO
ENSURE THE MOTOR AND PUMP ARE LEVEL AND SETTING
FIRMLY ON THE SUPPORT.
4. MAKING PIPE CONNECTIONS:
A. EXTREME CARE MUST BE TAKEN TO SUPPORT
ALL PIPING WITHOUT CAUSING ANY STRAIN ON
THE PUMP.
B. INSTALL PIPE HANGER ON THE PIPE SO THAT ALL
PIPING WEIGHT IS SUPPORTED BY THE HANGER
AND NOT BY THE PUMP OR THE CASING.
C. BOLT HOLES MUST LINE-UP WITHOUT PRYING TO
INSERT BOLTS.
D. WHEN TIGHTENING FLANGE BOLTS, PIPE
FLANGES MUST NOT BE FORCED TOGETHER.
E. CHECK VALVE SHOULD BE PLACED IN
DISCHARGE LINE BETWEEN GATE VALVE AND
PUMP DISCHARGE PIPE TO PREVENT LIQUID
FROM RUNNING BACK THROUGH THE PUMP AND
CAUSING REVERSE ROTATION. THIS IS
EXTREMELY IMPORTANT IN APPLICATIONS WITH
INTERMITTENT DUTY WHERE THE PUMP MAY BE
ROTATING BACKWARDS WHEN SERVICE IS
RESUMED. THIS WILL CAUSE DAMAGE TO THE
PUMP AND THE DRIVE MOTOR.
F. PRESSURE GAUGE SHOULD BE LOCATED AT THE
PUMP DISCHARGE, AS ALL PERFORMANCE DATA
IS TAKEN AT PUMP DISCHARGE.
MAINTENANCE
1. LUBRICATION: ALL PUMPS ARE LUBRICATED AT THE
FACTORY AND SHOULD NOT REQUIRE ADDITIONAL
LUBRICATION AT START-UP. A WELL PLANNED
MAINTENANCE SCHEDULE CAN ONLY BE DEVISED AFTER
CAREFUL OBSERVATION OF THE PUMP FOR THE FIRST SIX
MONTHS OF OPERATION AND THE LUBRICATION THAT
HAS BEEN REQUIRED. EACH PUMP INSTALLATION IS
UNIQUE AND REQUIRES A DIFFERENT LUBRICATION
SCHEDULE COMPATIBLE WITH THAT SPECIFIC
OPERATION.
TO LUBRICATE:
DO NOT LUBRICATE WHILE SHAFT IS IN MOTION.
A. REVIEW THE MOTOR NAME PLATE FOR TYPE OF
LUBRICANT TO USE. IF THIS DATA IS NOT ON THE
MOTOR NAME PLATE, CONSULT WITH THE
MOTOR PRODUCER TO OBTAIN THIS
INFORMATION.
B. LOCATE ZERK FITTINGS ON THE MOTOR. IF NO
ZERK FITTINGS ARE FOUND, THE BEARINGS ARE
SEALED FOR LIFE AND REQUIRE NO LUBRICANT.
ROTATION FROM
MOTOR END
5. MAKE ELECTRICAL CONNECTION TO CONFORM WITH
STATE AND LOCAL CODES. MOTORS ARE SUPPLIED WITH
A WIRING DIAGRAM. FOLLOWING THE WIRING DIAGRAM
FOR YOUR PARTICULAR ELECTRICAL REQUIREMENTS.
6. FILL PUMP AND SYSTEM WITH LIQUID. CHECK FOR ANY
LEAKS.
PRIMING
NO CENTRIFUGAL PUMP WILL OPERATE SATISFACTORILY
UNTIL IT HAS BEEN PROPERLY PRIMED. DO NOT ATTEMPT TO
PRIME PUMP WHEN OPERATING AND DO NOT UNDER ANY
CIRCUMSTANCES OPERATE THE PUMP WITHOUT BEING
COMPLETELY PRIMED. SOME OF THE MOST COMMON
METHODS OF PRIMING ARE FLOODED SUCTION, FOOT VALVE
IN SUCTION LINE, EJECTOR (STEAM, WATER OR AIR OPERATED)
AND VACUUM PUMP.
WITH FLOODED SUCTION, REMOVE THE AIR VENT IN TOP OF
PUMP CASING TO RELEASE ENTRAINED AIR.
WITH FOOT VALVE THE PUMP AND SUCTION PIPE MUST BE
FILLED WITH THE LIQUID BEING PUMPED. IT IS
RECOMMENDED TO FILL THE DISCHARGE PIPE SEVERAL FEET
ABOVE THE PUMP DISCHARGE, LEAVE VENT OPEN WHILE
FILLING PIPE AND PUMP. THE PUMP WILL REMAIN PRIMED
UNLESS THE FOOT VALVE LEAKS OR IF THE LIQUID IS
CONTAMINATED AND DOES NOT ALLOW FOOT VALVE TO
CLOSE TIGHT.
BUMP START THE MOTOR TO VERIFY CORRECT ROTATION.
UPON INITIAL START-UP, PUMPS MAY SEEM TO RUN TIGHT
AND HOT. THIS IS CAUSED BY BREAKING-IN OF OIL SEALS AND
BALL BEARINGS. PUMP WILL OPERATE NORMALLY AFTER
APPROXIMATELY 150 HOURS OF SERVICE. REVIEW THE MOTOR
TAG FOR MAXIMUM TEMPERATURE LIMITS.
START-UP
CHECK PUMP FOR VIBRATION LEVELS, BEARING
TEMPERATURE, AND EXCESSIVE NOISE. IF NORMAL LEVELS
ARE EXCEEDED, SHUT DOWN AND INVESTIGATE.
