1) CENTERLINE OF PUMP SUCTION (INLET) TO BE SLIGHTLY
HIGHER THAN CENTERLINE OF SUCTION (INLET) VALVE - SO
ANY AIR IN SUCTION SYSTEM PROMPTLY REACHES PUMP
AND IS EXPELLED
2) SLOPE BYPASS LINE SO LOW POINT DRAIN WILL FULLY
EMPTYRELIEF AND CHOKE VALVES AND ALL LIQUID IN
BYPASS CIRCUIT
3) DO NOT LOCATE PIPING OR OTHER EQUIPMENT IN FRONT
OF OR ABOVE PUMP FLIUD END PREVENTING SERVICING –
REFER TO MANUFACTURER FOR MINIMUM CLEARANCES
4) LOCATE CHARGING PUMP AT POINT SHOWN. – IF
CHARGING PUMP IS NECESSARY (FOR VOLATILE FLUIDS,
FOR EXAMPLE)
5) IF DESIRED, A TWO-WAY MOTOR OPERATED BYPASS VALVE MAY
BE USED RATHER THAN MANUAL TYPE – IT SHOULD BE DESIGN TO
OPEN AUOMATICALLY WHILE STARTING OR STOPPING
6) BYPASS LINE SHOULD FEED LIQUID INTO TANK BELOW MINIMUM
LIQUID LEVEL
7) TO REMOVE PIPING STRAIN AND VIBRATION A FLEXIBLE HOSE,
EXPANSION JOINT OR SWIVLE JOINT PAIR SHOULD BE
POSITIONED TO MINIMIZE EFFECTS OF PIPING THERMAL
EXPANSION, CONTRACTION AND PIPING WEIGHT
8) SUCTION SIZED FOR 1 ½ TO 2 FT/SEC MAX FLOW RATE.
DISCHARGED SIZED FOR 8 TO 10 FT/SEC MAX FLOW RATE –
SUCTION AND DISCHARGE MUST BE SUPPORTED AND
ANCHORED
9) TO PROTECT SUCTION SYSTEM AGAINST
HAZARD OF DISCHARGE PRESSURE ENTRY
(AS WHEN PUMP IS IDLE), A SMALL RELIEF
VALVE IS OFTEN CONNECTED HERE
10) ALL SYSTEM COMPONENTS MUST HAVE
ADEQUATE PRESSURE RATINGS FOR
OPERATING, STARTING AND UPSET
CONDITIONS. IN ORDER TO REDUCE
POTENTIAL HAZARDS, PARTICULAR
ATTENTION IS RECOMMENDED FOR THE
SURGE CONDITION THAT WILL RESULT
DOWNSTREAM OF THE REFLIEF VALVE
WHEN NORMAL DISCHARGE IS BLOCKED
-AS A GENERAL RULE, FLUID LEVEL MUST BE HIGHER THAN THE PUMP FLUID END AS PLUNGERS CANNOT LIFT FLUID. 10 FEET OF HEAD IS A GOOD RULE OF THUMB.
-CAUTION SHOULD BE TAKEN TO KEEP FITTINGS OUT OF THE SUCTION AND DISCHARGE PIPING AS THESE WILL RESULT IN POOR PERFORMANCE. EACH 90-DEGREE TURN IN
THESE LINES RESULTS IN GREAT LOSS OF PUMPING EFFICIENCY.
