CAUSES AND SOLUTIONS:

• Improper foundation – Check & do proper foundation.
• Misalignment of pump/motor coupling – Check & do proper alignment.
• Back pressure created from exhaust – Clean exhaust condenser/filter.
• Excessive flow rate of sealant – Check sealant temperature and maintain the temperature.

CAUSES AND SOLUTIONS:

• Scaling inside casing/impeller is jammed – Clean the pump and free the pump.
