    Why is my Goulds Pumps Water Pump not producing the rated flow or head?
    • O
      onewtonSep 14, 2025
      If your Goulds Pumps Water Pump isn't producing the rated flow or head, several factors could be responsible. Ensure the driver is wired correctly and receiving full voltage, as the impellers might not be rotating fast enough. Also, verify the impellers are spinning counterclockwise when viewed from above and check the engagement of the motor coupling. The total pump head might be too high, so check the pipe friction losses and consider using larger discharge piping. Inspect the impellers and bowls for any obstructions in the liquid passages. Check for and remove any obstructions in the pump suction inlet, as cavitation could be occurring. Finally, the impellers might be too high, requiring a reset of the impeller adjustment.

    What to do if my Goulds Pumps VIT Water Pump is not delivering liquid?
    • C
      Chad Summers DDSAug 25, 2025
      If your Goulds Pumps Water Pump isn't delivering liquid, consider the following: * The bowl assembly might not be submerged enough; adjust the liquid level in the sump accordingly. * The suction strainer could be clogged; remove any obstructions. * There might be an obstruction in the liquid passage; pull the pump and inspect the impeller and bowl. * The discharge head might not be properly vented; open the vent.

    Why is my Goulds Pumps Water Pump noisy?
    • A
      Angela RosalesAug 26, 2025
      A noisy Goulds Pumps Water Pump can be attributed to several factors: * The pump may be cavitating; increase the liquid level in the sump. * The shaft could be bent; straighten it as necessary. * Rotating parts might be binding, loose, or broken; replace parts as needed. * The bearings could be worn; replace them. * The discharge head might not be properly vented; open the vent.

    How to fix excessive leakage from the stuffing box of Goulds Pumps Water Pump?
    • J
      James HarveyAug 27, 2025
      Excessive leakage from the stuffing box in your Goulds Pumps Water Pump may be due to: * Defective packing; replace any worn or damaged packing. * The wrong kind of packing being used; consult an ITT representative.

    Why does my Goulds Pumps Water Pump start and then stop pumping?
    • A
      Allen KingSep 15, 2025
      If your Goulds Pumps Water Pump starts and then stops pumping, it could be due to several reasons. The pump may be requiring excessive power, or it might be pumping a liquid with a higher viscosity or different specific gravity than it was designed to handle, so test the liquid for these properties. Critical parts may have experienced mechanical failure, so check the bearings, wear rings, and impellers for damage. Ensure the impellers are not rotating too fast by checking the frequency on the motor. Also, realign the pump and driver if they are misaligned, and open the vent if the discharge head is not properly vented.

    Why does the seal squeal during operation in my Goulds Pumps Water Pump?
    • J
      Jonathan SnowSep 23, 2025
      If the seal squeals during operation in your Goulds Pumps Water Pump, there might be an inadequate amount of liquid at the seal faces. A bypass flush line is necessary, or if one is already in use, enlarge it to produce more flow.

    Why does my Goulds Pumps Water Pump take too much power?
    • A
      Amy RamseySep 7, 2025
      If your Goulds Pumps Water Pump takes too much power, inspect the impeller for damage and replace it if necessary. Check for any foreign objects lodged between the impeller and bowl and remove them. Test the liquid to ensure the specific gravity isn't higher than what the pump was designed for. Also, check for high viscosity or partial freezing of the pumpage, as these can cause drag on the impeller. Replace any defective bearings and check the shaft or shaft sleeve for scoring. If the packing is too tight, release the gland pressure and retighten it, ensuring some leakage. If there is no leakage, inspect the packing, sleeve, or shaft.

    How to troubleshoot a Goulds Pumps VIT that does not start?
    • K
      Kimberly SimpsonSep 8, 2025
      If your Goulds Pumps Water Pump isn't starting, check the electrical circuit to ensure it's complete and correct any open circuits. Reset the impeller adjustment if it's improperly adjusted, causing the impeller to be on the bottom. Verify the driver wiring is correct and receiving full voltage; consult the factory if needed. If these steps don't resolve the issue, the motor may be defective.

    Why does the seal leak on my Goulds Pumps Water Pump when nothing appears to be wrong?
    • T
      Thomas MckenzieSep 23, 2025
      If the seal leaks on your Goulds Pumps Water Pump when nothing appears to be wrong, the seal faces may not be flat, so relap or replace them.

    Why is the stuffing box overheating on my Goulds Pumps VIT Water Pump?
    • K
      Katie JonesAug 31, 2025
      If the stuffing box is overheating on your Goulds Pumps Water Pump, consider: * The packing being too tight; release the gland pressure and retighten, ensuring leakage. If there's no leakage, check the packing, sleeve, or shaft. * The packing not being lubricated; release the gland pressure, replace any burned or damaged packing, and regrease as necessary. * The wrong grade of packing being used; consult an ITT representative. * The stuffing box being improperly packed; repack the stuffing box.
