What is the consequence of misalignment between the pump and its drive system?

• A. Misalignment can cause belt wear, vibration, and mechanical failure; ensure alignment within manufacturer specs.
• B. Alignment improves color of paint.
• C. Misalignment only affects electrical wiring.
• D. Misalignment has no effect.

Answer: (A)

When the pump shaft and the drive system aren’t perfectly aligned, the belt and bearings experience uneven loads and wobble. That misalignment causes the belt to run off-center, increases side and axial forces, and puts extra stress on bearings, shafts, and couplings. The result is faster belt wear, more vibration, heat, and a higher chance of mechanical failure. Keeping the alignment within the manufacturer’s specifications helps ensure proper belt tracking, reduces unnecessary stress, and maintains efficient, reliable operation.

The other statements don’t fit because alignment doesn’t affect the color of paint, it isn’t primarily about electrical wiring, and it certainly does have an effect on performance and life of the system.
