Open First 10 ft (3 m) of column 0.015 in. (0.381 mm)
Each additional 10 ft (3 m) of
column
0.010 in. (0.254 mm)
Enclosed Bowl sizes up to 8 in. (20.32 cm) 0.12 in. (3.05 mm)

Set up the lubrication system
1. Connect the solenoid valve, if provided, and the oil lines.
2. Fill the oil reservoir with oil.
3. Check the lubricator feed and make sure that the oil reservoir is flowing freely.
In the case of a solenoid valve, temporary power connections are required.
4. Set the proper drops per minute on the regulator as this table shows:
The shaft is the headshaft (OD). The adjustment is a manual adjustment on the regulator valve.
Shaft size in inches Shaft size in millimeters Drops per minute per 100 feet
(30.48 meters) of shaft
0.75 to 1.00 19 to 25 mm 8
1.19 to 1.94 30 to 50 mm 16
2.19 and larger 55 mm and larger 20
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 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 discharge, check that tie rods are in place and
properly installed.
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.
