Removing air from an IPM (Industrial Percussion Manufacturing) drum pump—or any pneumatic drum pump—is typically necessary to prime the pump and ensure proper fluid transfer without airlocks. Here’s a step-by-step guide:
Ensure all tubing, fittings, and seals are correctly connected and airtight.
Verify the pump’s dip tube is fully submerged in the liquid (not sucking air).
Some IPM drum pumps are self-priming, but thicker fluids (like oils or syrups) may need manual priming.
For viscous liquids: Pour a small amount of liquid into the pump’s discharge tube to help create suction.
Method 1: Run the Pump Briefly Dry
Connect the pump to an air supply (~30–100 PSI).
Let it run for 5–10 seconds without liquid—this can help expel trapped air.
Submerge the intake tube fully and restart.
Method 2: Tilting the Pump
Tilt the drum or pump slightly to help air escape from the suction tube.
Method 3: Manual Air Release (if applicable)
Some models have a bleed valve—open it while running to let air escape.
Once air is purged, the pump should begin moving liquid smoothly.
If air bubbles persist, check for:
Leaks in fittings or tubing.
Cracked or worn seals (replace if needed).
Improper submersion (ensure the dip tube isn’t exposed).
| Problem | Solution |
|---|---|
| Pump won’t prime | Check for blockages, increase air pressure slightly. |
| Erratic flow/air bubbles | Tighten connections, inspect for leaks. |
| Weak suction | Ensure dip tube is deep enough; clean clogged filters. |
| Pump loses prime mid-use | Verify liquid level hasn’t dropped too low. |
✔ Use a check valve (if not built-in) to prevent backflow.
✔ Store the pump vertically to keep fluid in the tubing.
✔ Regularly inspect seals and O-rings for wear.
If air removal fails repeatedly, the pump may have:
A damaged diaphragm or piston.
Worn internal valves (needing rebuild/replacement).
