    Pumps are classified into two main categories.

    1. Positive Displacement Pumps

    2. Dynamic Pressure Pumps

    Positive Displacement Pump is the pump which operates by forcing a fixed volume of fluid from the inlet pressure section of the pump into the discharge zone of the pump. The following pumps come into this category,

    - Reciprocating Pumps
