The impeller is generally the most difficult pump component to repair and the most expensive to replace. This session will look at case histories of failed pumps and the steps to determine the cause of failure

• Erosion, corrosion, cavitation or wear: What happened to this impeller?
• How to spot the tell-tale signs
• What operational conditions led to impeller damage

The pump repairs are completed! Now the pump needs to be tested. This webinar will discuss the procedures for the basic tests that can be performed on pumps that have been repaired in the service center.

Final testing of pumps can include:

• Operational Tests
• Seal Leakage Test
• Motor Chamber Leakage test (submersibles)
• Casing Pressure Test

While some of these tests are not difficult to perform, knowing the methods and limits will help service centers to confidently deliver quality pump repairs.

This session examines features, benefits and drawbacks of both conventional and alternative methods of cleaning electric motors. Methods covered include:

• immersion tanks
• steam cleaning
• parts-washing machines
• pressure washers
• abrasives 
• ultrasonic devices

Environmental options for handling waste by-products are also addressed. If you are considering changing your cleaning methods, this webinar is for you.

Cavitation is one of the most damaging forces to centrifugal pumps. Understanding the causes, symptoms and solutions for cavitation is essential to service technicians and engineers. This webinar will "bring you up to speed" on cavitation in centrifugal pumps.

This webinar will focus on:

• A review seal basics
• Seal materials for primary and secondary seals
• How to determine spring tension values
• How to calculate PV values
• Seal flush plans

This webinar will take the mystery out of pump curves and provide attendees with the necessary knowledge to determine pump operating points, efficiency and horsepower. The elusive parameters that determine if a pump is likely to cavitate will also be discussed.

Who should attend
This seminar is intended for application engineers, sales personnel, managers and interested pump technicians and supervisors.

This webinar focuses on submersible pumps:

• Types of submersible pumps
• Tips on seal arrangements
• Common repair procedures
• Cables and cable entries
• Testing submersibles in the service center

We’ve covered how to assess impeller damage in a previous webinar. Now learn how to fix that damage. This webinar will cover: 

• Replacing/repairing wear rings
• Repairing cavitation damage
• Impeller replacement options
• Dynamic balancing impellers

Most service center technicians and managers know the general properties of a few common grades of steel used for motor and pump shafts. This webinar will expand that knowledge by defining the important parameters of a range of steel grades and how they affect performance. The affects of thermal treating and basic metallurgical terminology will also be presented.

Who should attend
This webinar is intended for service center supervisors, managers and machine shop technicians.

"Water finds a way." The quote may be anonymous but that is the reality for anyone working with submersible pumps. Sometimes neglected, the cable entry point can be a source of moisture entrainment that leads to damp windings and ground failures. This webinar will address this important link in sealing submersible pumps.

The slender dimensions of many pump shafts make them susceptible to distortion, which affects pump performance and reliability. This webinar will present a methodical approach and effective techniques for measuring and correcting shafts which are bent or twisted.

Who should attend
This webinar is intended for service center supervisors, managers and machine shop technicians.

Vertical turbine pumps are used extensively in every segment of industry. Although they are not complex, repairing them in the service center can present a few challenges. This webinar will present some approaches and procedures that experience has shown will make the job easier.

The rules of thumb often applied to journal bearings in horizontal machines don’t apply to vertical machines. Vertical turbine pumps are a common example. This webinar will explain the characteristics of bearing in these pumps and provide examples of manufacturers specifications. In addition, specialty bearing materials will be discussed in regard to applications, specifications and installation.

Who should attend
This webinar will be most useful for service center technicians and engineers. The content will be beneficial for supervisors and managers who are responsible for pump failure analysis and testing.

When motors are installed on top of vertical pumps, high vibration is a common problem. The problem may be mechanical, hydraulic or structural. This webinar will provide an understanding of the nature of this style pump and the various forces essential to diagnosing and correcting vibration problems on vertical pump motors.
