Goulds Pumps Vertical Turbine Pump VIT-FF 16D

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

Thrust pot lubrication guidelines

Check that the pump is shipped without oil

Ensure oil-lubricated bearings are lubricated at the job site

Refer to Thrust Pot IOM for lubrication requirements

Oil level inspection when not operating

Measure the 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?

Oil level inspection when operating

Check if the oil level is lower than the required level as indicated on the oil sight gauge

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

6.2 Adjust and replace the packing

Check conditions for packing adjustment

Is the packing adjustment necessary based on conditions?

6.2.1 Adjust the packing when leaking is excessive

Tighten the gland nuts one-quarter turn with the pump in operation

Has the leakage decreased to two drops per second?

Shut down the pump if leakage continues to exceed two drops per second

Allow the packing to compress until the gland is about to contact the upper face of the stuffing box

Remove the split gland, add one extra packing ring, and readjust

Impeller Replacement Guidelines

Check impeller vanes for grooves deeper than 1.6 mm or wear more than 0.8 mm

Inspect vane edges for cracks, pitting, or corrosion damage

Remove the Bowl and Impeller Wear Rings

Remove setscrews or grind off tack welds if present

Cut two V-shaped grooves on the bowl or impeller wear ring 180° apart

Knock the end of one half of the ring in and pry the ring out

Machine the wear ring off for high-alloy materials
