Dynamic Pump

A dynamic pump is a type of pump which causes the fluid to move from inlet to outlet under its own momentum. The dynamic pump is activated by developing a high liquid velocity and converting the velocity to pressure in a diffusing flow passage. Dynamic pump is usually less efficient than positive displacement pump, but also has lower maintenance requirement. The pump is also able to operate at fairly high speed and high fluid flow rates.

Types of Dynamic Pumps:
Dynamic pump is a category of pumps under which there are several classes. Fluid motion can be rotary or linear. Accordingly, dynamic pumps can be classified as follows:

• Rotary Dynamic Pump : This type of pump contains a rotating part called the impeller inside a stationary cavity called the volute. The impeller forces the fluid to rotate, and thereby to move from inlet to outlet under its own momentum. Various rotary dynamic pumps are:
  
  
  • Turbo pump
  • Submersible pump
  • Centrifugal pump
  • Axial flow pump
  
  
  
• Linear or reciprocating dynamic pump : Various types of linear dynamic pump are:
  
  
  • Ejector pump : Steam ejectors are used to cool bleach water. This enables to retain the chlorine. These discharge a boiler into a tube, sucking water vapor out from above a sealed tank. The water inside slowly cools.
    
    
  • A well pump is also a dynamic pump.

Applications of Dynamic Pump:

• Petroleum Industry
• Paper Industry
• Plumbing System
• Drainage and Irrigation System
• Marine Applications
• Residential Applications
• Agricultural and Industrial Applications
• Pharmaceutical Industry etc.
