Introduction to Positive Displacement Pumps

 After finishing this lesson, you will be able to describe the basic design and operation of positive displacement pumps and identify operating conditions under which they are commonly implemented. Additionally, you will be able to discuss the operational differences between the two main classes of positive displacement pumps, which are reciprocating and rotary. • Discuss the operating principle behind positive displacement pumps • State three operating conditions under which a positive displacement pump would best be employed • Identify the basic components of a positive displacement pump • Discuss the difference between the basic operations of reciprocating and rotary positive displacement pump categories
