Webinar: Mastering Pump Efficiency: Defeating Pump Killers for Reliable Operation and Energy Savings
Join Hydro’s Dr. Gary Dyson in learning about increasing reliability and reducing energy usage in this webinar hosted by Chemical Processing magazine.
This webinar will provide an overview of some of the most common “pump killers,” including the fundamentals behind the problem and what can be done to improve operation. Focus areas include NPSH and cavitation, the effect of operating at low flows, and abrasion and erosion. Each failure mode will be reviewed with an eye to improving reliability and saving energy. A case study will provide practical application of the material as it highlights a project that improved pump performance, reduced energy usage, and obtained reliable operation for a “bad actor” cooling water pump at a chemical plant.

The Hidden Dangers of Shaft Stiffness
The pump shaft is the central component of the rotating element and is responsible for transmitting energy to the rotating components. The shaft carries the impellers, sleeves and couplings for the rotating element assembly. The stiffness of the combined assembly is responsible for ensuring that the pump stationary components do not come into contact with the rotating components.
Unfortunately, this is not always achieved and many pump rotors cannot be described as classically stiff. This can have dire consequences for machine reliability, particularly if, during the rotor build process, the technicians are not aware of the subtleties of the machine design.
