Why is my ITT Goulds Pumps NM 3196 i-FRAME not delivering liquid?

  If your ITT Water Pump isn't delivering liquid, several issues could be the cause. First, the pump might not be primed; re-prime it, ensuring both the pump and suction line are full of liquid. The suction line could also be clogged, so remove any obstructions. Another possibility is a clogged impeller, which can be resolved by back-flushing the pump. Ensure the shaft rotates in the correct direction, matching the arrow on the bearing housing or pump casing. Insufficient submersion of the foot valve or suction pipe opening can also cause this; consult an ITT representative for the correct depth and use a baffle to eliminate vortices. Finally, a suction lift that is too high can prevent liquid delivery, so shorten the suction pipe.

What to do if ITT Goulds Pumps NM 3196 i-FRAME is not producing the rated flow or head?

  Victoria DavidsonAug 18, 2025
  If your ITT Water Pump isn't achieving its rated flow or head, there are several potential causes. An air leak from a faulty gasket or O-ring could be the culprit; replace these components. Similarly, an air leak in the stuffing box can cause issues; replace or readjust the mechanical seal. A partly clogged impeller can also reduce performance; back-flush the pump to clean it. Excessive clearance between the impeller and pump casing can be a factor, so adjust the impeller clearance. Ensure sufficient suction head by fully opening the suction-line shutoff valve and clearing any obstructions in the line. Lastly, a worn or broken impeller will impact performance, so inspect and replace it if necessary.

Why does my ITT Goulds Pumps NM 3196 i-FRAME start and then stop pumping?
- D
  Derek WrightAug 26, 2025
  If your ITT Water Pump starts but then stops pumping, it could be due to a few reasons. The pump may not be properly primed; re-prime it, ensuring that both the pump and suction line are full of liquid. Air or vapor pockets in the suction line can also cause this issue; rearrange the piping to eliminate these pockets. Finally, an air leak in the suction line can be the cause; repair the leak to resolve the problem.

  If the bearings in your ITT Water Pump are running hot, there are a few potential causes. First, the pump and driver may not be properly aligned; realign them. Insufficient lubrication can also lead to overheating; check the lubricant for suitability and level. Finally, inadequate cooling of the lubrication can be a factor; check the cooling system to ensure it's functioning correctly.
