This course will introduce delegates to the different types of pumps and their associated terminology. Centrifugal and positive-displacement pumps, packing, mechanical seals and sealing systems, bearings and couplings are discussed.
The application of the different types of pumps is considered along with their suitability for different operational duties. Pump operation, troubleshooting and maintenance are dealt with in-depth. The course will feature:
- Enable delegates to optimize the operation and maintenance of different types of pumps.
- Give delegates the confidence to carry out failure analyses on pumps thereby avoiding repetitive failures.
- Give the delegates the ability to quickly and efficiently troubleshoot pumping machinery problems.
By the end of this course delegates will be able to:
- Identify and understand the different types of pumps.
- Operate pumps as close as possible to the design efficiency.
- Identify and monitor pump efficiency, availability and reliability.
- Develop knowledge about selection, operation and maintenance strategies.
- Identify and troubleshoot pump & associated machinery problems.
