CENTRIFUGAL PUMP | Pre-Commissioning Checklist

July 3, 2022 |

This pump commissioning checklist can be used and completed throughout the project and its different stages:

  • delivery,
  • storage,
  • installation &
  • pre-commissioning

Once completed, the full functional testing of the pumps can be conducted.

To read our article on Pump Testing see 'Pump Commissioning and Alignment'

Delivery Inspection

Once the Pump arrives at the site, usually delivered by a transport company, and before being accepted into storage, the following should be checked with the driver.

Any damage that is noted should be reported to the manufacturer/supplier within 3 days in writing, supported with photographs.

RefInspection/Task
1Supplier's consolidated delivery ticket is available, showing all equipment and ancillaries for inspection and being used to check against.
2A copy of the order that was sent to the supplier is available for reference and is being used to check against
3Equipment is packaged and crated in separate boxes for maximum protection.
4The pump & pump motor nameplate and details match the purchase order.
5Delivery protection is dry.
6Pump/s are dry internally.
7The external casing of the pump/s is undamaged.
8All base frames, if ordered are included.
9All pipework connections are the correct size.
10Flanges and Pipework connections are undamaged.
11All ancillaries are included in delivery as per the order and delivery note.
12Spin the pump impeller to ensure it is not damaged and out of line
13Replace and protection that has been removed

Storage Inspection

Storage Area

If the pumps are to be placed into storage on-site before installation, there will be an inspection completed checking the following.

RefInspection/Task
1The area is internal and will not be affected by the weather. [if the pump is not rated for external use]
2The surface where the equipment is to be placed is flat.
3The area is well covered and protected.
4The area is well ventilated and has no risk of high humidity.
5The area is clean & dust-free.

Storage of the Pump

Prior to the pump/s being placed into storage, the following should be checked.

RefInspection/Task
1Pumps will not be stacked.
2Pumps will not have materials stacked on them.
3All ancillaries will be placed in a safe and secure location, so items do not go missing or get damaged.
4All original packaging is intact and not removed.
5Pipework/connection caps protecting the flanges are not removed.
6The pumps will be raised from the floor to allow airflow and stop the risk of water ingress.

Pre-Installation Inspection

Prior to the pumps being installed, the following should be checked.

RefInspection/Task
1The plinth/base is ready, flat, and level & can bear the weight of the installation.
2The room/area is dry and watertight.
3The area being installed is not prone to flooding or ponding of water.
4The room/area the pumps will be installed into is clean and dust-free. If there is dust/construction work, then the pumps should be protected.
5If the pumps are installed externally, if there is a buildup of snow, it will not affect the pump/s operation or maintenance requirements.
6All pipework connections can be independently supported and not supported by the pump/s. The best practice is to install self-supporting brackets prior to the connection.
7Check to ensure that all connection kits containing gaskets and bolts are available to allow bolting up the pumps to the system.
8Remove all transport feet and bolts.

Maintenance/Access

RefInspection/Task
1There is enough space allowed around and above the pumps once installed to perform maintenance and remove components. [check the manufacturer's maintenance instructions for requirements]

Pre-Commissioning Inspection

Once the pumps have been installed and before the functional testing and commissioning phase occur, the following will be checked.

General

RefInspection/Task
1Document the information of the pump from its nameplates and cross-reference with the specified information to ensure correct.
2Check that all transport bolts and feet are removed.
3Ensure pump/s are level.
4Ensure all gaskets are installed and sealed.
5Ensure that all bolts are installed as per the manufacturer’s instructions.
6Ensure pumps are aligned in accordance with the manufacturer’s instructions.
7All vibration mounts installed.
8Seismic restraints, where required, installed.
9All components, including valves and controls, are labeled in line with the project naming convention.
10Operation and startup manual for the Pumps available.

Electrical General

RefInspection/Task
1Pump/s and components are fully earthed in line with the manufacturer’s instructions.
2Earthing has been tested.
3Emergency disconnect installed for each pump in line with NFPA/local code requirements.
4Electrical voltage from the site matches the pump required voltages.
5All cabling is installed and connected on the correct containment and not damaged.
6All cabling has been tested/torque tested.
7A local motor control panel [LMCP] has been installed.
8The local motor control panel has been electrically tested.
9All electrical cabling is labeled in line with the project naming convention.

Variable Speed Drive

RefInspection/Task
1A variable speed drive has been installed.
2Variable Speed Drive [VSD] has been electrically tested
3Variable speed drive has been functionally tested.

Controls System Interlocks

RefInspection/Task
1Control’s system installed as per the drawings and control logics and interlocked with other cooling/heating plant.

Pumps/Pipework

RefInspection/Task
1Ensure that the pump is installed in the correct orientation to the system pipework and the impeller rotates in the correct direction.
2Ensure that the pipework and connections are the correct size and in line with the drawing.
3Check that the pipework installation is in line with the manufacturers information. There is usually a requirement of the straight length, connecting to the inlet side of the pump, be at least 10x the pipework diameter.
4Ensure the installation of the pipework will not put stress on the Pump connections or create vibrations.
5The materials used between the pump/s and the chilled water system will not cause Electrolysis.
6Pipework that is to connect to the pump/s has been weld tested.
7Pipework that is connected to the pump/s has been pressure tested.
8Pumps have been primed in line with the manufacturer’s requirements.
9Pipework that is connected to the pump/s has been cleaned and flushed.
10The system has been bled and the air removed.
11Pipework is insulated and vapor sealed.
12Insulation is labeled
13All pressure gauges installed and display scale as per design requirements.
14All valves/control valves are installed and in the correct direction.
15All commissioning devices are installed.
16All Strainers are installed and inspected to ensure the mesh is clean.
17All expansion/rubber bellows are installed at least 1.5x the pipe diameter away from the pump for the inlet and the outlet.

Controls

RefInspection/Task
1Ensure all sensors and instruments are installed as per the control logic/pipework schematic drawings [pressure sensors, flow sensors, etc.]
2All sensors are calibrated.
