Installation and startup checklist
Use this checklist in conjunction with the standard instruction manual furnished with the equipment.
Initial each completed item or write N/A if the item is not applicable. After you complete this checklist,
forward a copy to the VPD field service for entry into the quality assurance records. Use a separate
checklist for each individual pump.
Part 1: System and installation inspections
Check Checked
Check that the pump foundation is level to within 0.005 in. per ft. (0.0123 cm per m) of diameter. For API units,
the level requirement is 0.001 in. per ft. (0.003 cm per m) of diameter.
Check that the foundation can handle the weight and loading of the pump.
Check that the foundation is properly grouted using a high quality non-shrink grout.
Check that all the anchor bolts are tight.
Check that the suction and discharge piping is properly supported and that there is no excess nozzle loading on
the discharge flange.
On units with flexible or expansion joints attached to the pump suction or discharge, check that tie rods are in
place and properly installed.
Check that the suction valve is fully open.
Check these items for all valves:
• Operate freely
• Properly installed for the direction of flow
• Have the proper pressure
Check where the pumped fluid is going and that the system is properly lined up for the test.
Check that the pumped fluid supply will be continuously available for the duration of the test.
It is very important that the initial run is at least ten minutes in duration in order to completely flush the pump.
If possible, check the cleanliness of the pumped fluid and piping. If you are present during the installation, check
that the sump, barrel, and piping are clean.
Part 2: Pump assembly pre-start inspections
Check Checked
Verify that the drivers are properly lubricated before start-up. On drives with grease-lubricated motor bearings,
insist that the motor vendor grease them on-site. Lubrication information is located on special motor tags or in
the motor manuals.
Determine the allowable number of cold/hot starts with the motor vendor.
The general rule of thumb is two cold or one hot start per hour. Exceeding the recommended starts breaks
down the motor insulation and can cause failure. Megger the motor if possible.
