Goulds Pumps Vertical Turbine Pump VIT-FF 8A

Thrust pot lubrication guidelines

Verify that pumps are shipped without oil

Ensure oil-lubricated bearings are lubricated at the job site

Refer to Thrust Pot IOM for lubrication requirements

Check oil level when not operating

Measure oil level in the sight gauge

Is the oil level between 0.635 to 0.3175 mm (1/8 in. to 1/4 in.) from the top of the oil sight gauge?

Is the oil level lower than the required level as indicated on the oil sight gauge?

Check that the foundation and the hold-down bolts are tight.

Confirm completion of initial procedures

Verify mechanical seal lubrication and piping connection

Verify operation and regulation of cooling, heating, and flushing lines

Verify connections to driver and starting device match wiring diagram

Verify voltage, phase, and frequency on motor nameplate agree with line current

Rotate shaft manually to ensure impellers are not binding

Verify driver bearings are properly lubricated and check oil level in housing

Verify auxiliary seal components are properly vented

Replacement guidelines — Impeller replacement

Replace impeller vanes if grooved deeper than 1.6 mm or worn evenly more than 0.8 mm.

Replace vane edges if cracks, pitting, or corrosion damage are visible.

Remove the bowl and impeller wear rings

Remove the setscrews or grind off the tack weld if present.

Cut two V-shaped grooves on the bowl or impeller wear ring approximately 180° apart using a diamond-point chisel.

Knock the end of one half of the ring in and pry the ring out using a chisel or drift punch.

For high-alloy materials, machine the wear ring off using a lathe, ensuring not to damage the ring seat.

4.4.11 Set up the lubrication system

Observe instructions on the submittal document.

Fill the oil reservoir with oil.

Check the lubricator feed and ensure the oil reservoir is flowing freely.

Set the proper drops per minute on the regulator based on shaft size.

Is synthetic turbine oil ISO VG 32 used for general applications?

Consult ITT for more specific data if needed.
