Checklist : Pumps Layout

During design of Pumps Equipment Layout and Piping Layout, certain points need to be taken into consideration for optimal design. Some of these points are covered in following checklist. This checklist can be used at design stage as well as during 3D Model Review.

SrCheck ItemDone
1Pump is located close to equipment from which it taking its suction
2Pump not located under pipeway in process unit.
3Pump motor is toward Rack
4Centreline of Discharge Nozzles on common centreline for rows of pumps as far as possible
5Pump Discharge nozzle minimum 1 m from rack
6Sufficient clear space provided above pump for motor removal
7Sufficient gap between pump foundation and other structures for easy removal of pump.
8Stress Analysis of Pump piping with Supporting is done.
9Pump nozzle loading due to piping is less than vendor allowables
10Strainer in Suction is easily removable.
11Check valve installed in discharge line of centrifugal pump.
12Strainer is located before any reduction in pipe size.
13Suction piping minimised to reduce pressure drop and vapour pockets.
14Pump NPSH Checking done with process department
15Top flat reducer as close as possible to Suction nozzle for front suction nozzle pump.
16Piping Valves readily operable from grade
17Handwheels of Valves within perimeter of pumps as far as possible.
18Clear Aisle of 1000 mm available between adjacent pumps
19Monorail provided for large pumps if no access possible for mobile equipment. (>= 75KW)
20Pump not located within funded (dyked) tank areas.
21Pumps not located below equipment handling hydrocarbon liquids.
22Water Sprinkler / Spray system provided for pumps handling class A Fluids.
