Generic Failure Modes for Vertical Pumps provides an in-depth understanding of generic failure mechanisms for vertical turbine, can, and mixed flow pumps. This training enables identification of root causes and application of cost-effective solutions to achieve best-in-class performance and longevity. This training will positively affect the “bottom line” by providing information to help eliminate pump-related forced outages, achieve best-in-class reliability and life, and reduce annual pump-related operating & maintenance costs

Learning Outcomes:

• Identify critical failure mechanisms for vertical pumps
• Understand state-of-the-art upgrades to eliminate failure mechanisms
• Apply diagnostic methods based on pump design and observed condition
• Calculate rotor critical speed and required submergence
• Understand how sump-to-pump relationship can affect reliability
• Understand hydraulic rerates’ role in system and energy optimization
• Calculate annual energy savings from hydraulic modifications

Chapter Summaries:

CHAPTER 1: WET CRITICAL SPEEDS

This chapter gives an overview of wet critical speeds as a failure mode in vertical pumps, detailing causes such as loss of stiffness due to increased bearing clearance. It discusses effects of operating at critical speed and determination methods, while providing solutions to improve pump efficiency and life.

CHAPTER 2: COMMON FAILURE MODES

This chapter covers various failure modes in vertical pumps including structural resonance, suction recirculation, component corrosion, erosion, stress corrosion cracking, and sump-related issues. It discusses causes, effects, determination methods, and solutions to enhance pump performance and availability.

CHAPTER 3: POOR PERFORMANCE AND OTHER FAILURES

This chapter addresses poor pump performance as a failure mode, with causes such as internal recirculation and increased rotor lift. It discusses effects, determination methods, and solutions to reduce performance issues. Additionally, it covers other failures like high bearing temperature, motor amps, noise, pump seizure, and seal leakages, along with potential upgrades to mitigate these issues.
