Pump And Classification Of Pump

What is Pump?

         Pump is a very common device useful in all the industries. Pump is device that moves fluids (liquids, gases) or sometimes slurries by mechanical action.


CLASSIFICATION OF PUMP

      Generally pumps are classified by their mechanical configuration and their working principle.
 Pumps are classified mainly in two categories :








1. DYNAMIC PUMPS :

                        Dynamic Pump is a kinetic machine in which energy is continuously imparted to the pumped fluid by means of rotating impeller, propeller or rotor, in contrast to a positive displacement pump in which a fluid is moved by trapping a fixed amount of fluid and forcing the trapped volume into the pump's discharge. Centrifugal Pumps are the most common type of pumps used in industries.


2. POSITIVE DISPLACEMENT PUMPS :

                       Positive displacement pump has an expanding cavity on suction side and a decreasing cavity on the discharge side. In these types of pumps liquid flows into the pump as the cavity on the suction side expands and liquid flows out of the discharge as the cavity collapses. The volume is a constant throughout each cycle of operation. As shown above positive displacement pump can be divided into two types : Reciprocating Type and Rotary Type Pump. Piston pump and Diaphragm Pump are the examples of Reciprocating Type Pump. Gear Pump, Lobe pump, Vane Pump , Screw Pump and Plunger Pump are the examples of Rotary Type Pump.
