Pump Repair and Maintenance
Available in both virtual and in-person, instructor-led formats, this two-day hands-on Pump Repair & Maintenance course is designed to bring students up to speed in their knowledge of field pump repair, maintenance and servicing as quickly and efficiently as possible.
Description
This course is suitable both for novice technicians seeking the fundamentals of pump repair as well as experienced technicians seeking skills improvement or a refresher. The course covers pump design, types, parts, common causes of pump failure, repair techniques, and predictive maintenance for pumps. The goal of the course is to ensure that students understand the causes of pump failure, how to bring pumps back to life when they fail, what they should learn from those incidents, and how to reduce the risk of future failures.
