**Last week, a technician asked:**
\n*”How do I adjust a non-cartridge mechanical seal when it’s leaking?”*<\/p>\n
Here’s the answer \u2014 **don’t rush to take it apart**. Follow these three simple steps while the pump is still assembled. It saves time and effort.<\/p>\n
—<\/p>\n
### Step 1 \u2013 Push the Seal Evenly<\/strong><\/p>\n Loosen the set screw on the stationary ring. **This alone fixes 70% of leaks** caused by a stuck spring.<\/p>\n ### Step 2 \u2013 Check the Flushing Fluid<\/strong><\/p>\n Make sure the flushing fluid flows freely. ### Step 3 \u2013 Keep Inlet Pressure Stable<\/strong><\/p>\n Stable inlet pressure prevents cavitation (running dry or forming bubbles).<\/p>\n —<\/p>\n ### Still leaking after pushing?<\/p>\n That means either:<\/p>\n – The seal faces are worn out, or **Do not keep pushing again.** – Is the O-ring flattened or hard? ### If you see any of these problems \u2013 act immediately.<\/p>\n Remove the whole mechanical seal and replace it with a brand new one. —<\/p>\n ### Key Reminder<\/strong><\/p>\n For a non-cartridge mechanical seal: The repair time you save is worth far more than the cost of a new seal.<\/p>\n —<\/p>\n ### Quick Rhyme for the Job<\/strong><\/p>\n > *First tighten the rotating ring and check the conditions.* —<\/p>\n **Follow for more maintenance tips.

\nUse two iron bars to push the seal from opposite sides until the rotating ring and stationary ring touch.
\nThen tighten the fixing screws evenly, moving from corner to corner.<\/p>\n
\nIt carries away heat caused by friction.<\/p>\n
\n– The O-ring has aged.<\/p>\n
\nTake the pump apart and pull out the seal. Check:<\/p>\n
\n– Does the stationary ring’s mirror surface have scratches or deep grooves?<\/p>\n
\n(Remember: tighten the cover screws evenly and diagonally.)<\/p>\n
\n**Push once. If it still leaks, replace it without hesitation.**<\/p>\n
\n> *Push once \u2013 if it leaks, swap out the whole assembly.*<\/p>\n
