Pump Basics, centrifugal and reciprocating

Pumps work by creating a pressure difference that causes the fluid to move. There are two main types of pumps: positive displacement pumps and dynamic pumps. Positive displacement pumps trap a fixed amount of fluid in a chamber and then force it out of the chamber by reducing the volume of the chamber. This type of pump can generate a high pressure but is typically not as efficient as a dynamic pump. Examples of positive displacement pumps include Reciprocating pumps, diaphragm pumps, and gear pumps. Rotary pumps use rotary motion to transfer energy to the fluid. The most common type of dynamic pump is the centrifugal pump, which uses a rotating impeller to create a centrifugal force that moves the fluid. Centrifugal pumps are efficient and can move large volumes of fluid, but they cannot generate as high a pressure as positive displacement pumps. Other types of dynamic pumps include axial pumps and mixed-flow pumps. In this playlist you will find the chief types of pumps and connected theories. Dr. Amit MAndal
