Class Description:
PURPOSE OF TRAINING
The title of this seminar says it all – this Pump Repair and Maintenance training seminar helps students understand what to do when a pump stops working and how to repair it.
Broken pumps can have drastic consequences at your facility. Overall, this training program is designed to teach technicians how to bring pumps back to life when they fail, what they should learn from those failures, and then what to do to make sure they never happen again.
