Misaligned couplings

Loose or broken parts

Excessively worn gears

Worn or faulty bearings

Low liquid level or excessive forces in tank

Excessive backlash or shaft end play

Loose, Bent, or missing impeller blade

Magnets over torqued

Recheck Alignment

Check for breaks or cracks. Tighten all bolts.

Check shimming for proper contact. Check possible machine overload. Keep oil clean. Replace gears if necessary.

Check alignment, adjustment and possible overload. Clean and flush reducer, replace worn bearings and add new lubricant as required.

Turn mixer off and return tank level to 2' above lower impeller before resuming operation.

Check for worn bearings, gears and proper shimming.

If loose, replace and tighten all bolts. If blade is missing or bent, replace blade with proper size and type.

Reduce viscosity or specific gravity of product

Obstructed air flow

Unit operating over thermal rating

Check air supply for proper motor fan circulation. Avoid high surrounding ambient temperatures.

Check rating with actual load.

Worn or damaged oil seals

Foaming oil

Replace with new seals. Avoid inserting seal over sharp edges.

Replace oil with proper type (non-foaming)
