Positive Displacement Pumps :  Rotary Gear Pump :  A  rotary gear pump  is a positive displacement  pump  which employs a rotor and idler  gear  assembly to generate its flow. As the rotor  gear  drives the idler  gear , the space caused by the crescent offsetting the  gears  and the meshing of the  gear  teeth displace the fluid, expelling it to the discharge port. Rotary Screw Pump :  A  screw pump  is a type  of rotary pump  which is equipped with  screws  that mesh together and rotate within a cylindrical cavity or liner. The fluid enters from the suction side  of  the  pump  and moves linearly along these inter-meshing  screws  to the discharge side  of  the  pump .  Rotary Vane Pump :  A  rotary vane pump  is a positive-displacement  pump  that consists of  vanes  mounted to a rotor that r...

 Types and Classification of Pumps Introduction of Pumps : Pump is a machine or mechanical equipment which is required to lift liquid from low level to high level or to flow liquid from low pressure area to high pressure area or as a booster in a piping network system. Principally, pump converts mechanical energy of motor into fluid flow energy.  Types of Pump :  1. Positive Displacement Pumps 2. Rotodynamic Pumps Types of Positive Displacement Pumps :  u   Rotary Pumps: 1.    Gear pump: 2.    Screw Pump 3.    Rotary Vane u Reciprocating Pumps: 1. Plunger Pump 2.
