Course Description
Pumping systems account for nearly 20% of the world’s electrical energy demand and range from 25-50% of the energy usage in certain industrial plant operations
There are lots of pump types available, but which one is right for you? Understanding which pump type is right for your application is critical to reduce costs and increase the life of your pump and system
Centrifugal
pump single or multistage is the Best pump choice for lower viscosity liquids and high flow rates. No pulsations that may be found in some positive displacement pumps.
Multi-stage centrifugal pumps are now primarily used in this severe service. Two typical styles of multi-stage centrifugal pumps—barrel and horizontally split pumps are offered by different manufacturers.
