Pumps are devices used to raise, compress, or transfer fluids by mechanical action. Various types of pumps are available and are used depending upon the requirement. Pumps play a major role in a system. So, if there is a leakage, the entire system gets collapsed. The most effective method of preventing this leakage is by using seals. One of the best way to make these pumps function properly is by using lubricants. It reduces friction and also the noise when the pump operates and make them function smoothly for a longer period.
This course is designed to help students to become knowledgeable about pumps, sealings, lubricants, friction, and additives.
After completion of this course, students will know about pumps, its types, performance chart of the pumps, sealings and selection of lubricants & viscosity.
