Goulds Pumps Vertical Turbine Pump VIT-FF 14H

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

Allow time for seal adjustment if slight leaks occur at start-up

Run pump continuously if leaks decrease while running

Inspect for constant leaks during operation

Check for secondary seal damage or warped/cracked seal faces if constant leaks occur

Replacement guidelines — Mechanical seal checks

Check shaft or sleeve for pits, burrs, or sharp edges

Polish shaft or sleeve with fine emery cloth to remove burrs and sharp edges

2.4 Pump and bowl assembly storage requirements

Rotate the shaft and bowl assembly shaft counterclockwise at least 3 turns

Ensure the shaft is not left in a previous or extreme position

Check that the shaft rotates freely

2.4 Pump and bowl assembly storage requirements

Inspect the unit to ensure all preservatives are intact

Seal all pipe threads and flanged pipe covers with tape

Renew rust preventative on all uncoated surfaces

2.4.1 Extended long-term storage for partially assembled pumps

Replacement guidelines — Impeller replacement

Replace impeller vanes if grooved deeper than 1.6 mm | 1/16 in. or worn evenly more than 0.8 mm | 1/32 in.

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

Remove the bowl and impeller wear rings

Remove locking methods from wear rings

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, set up the bowl or the impeller in a lathe and machine the wear ring off.

Installing the turbine bowl and impeller wear ring

6.2 Adjust and replace the packing

Check conditions for packing adjustment

Is the packing in an Ex-classified environment?

Ensure packing is not over-tightened to less than one drop per second

6.2.1 Adjust the packing when leaking is excessive

Measure leakage rate (drops per second)

Is leakage rate more than two drops per second?

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

Has the leakage decreased to two drops per second?
