Advantages and disadvantages of centrifugal pump

Centrifugal pump was fairly simple in nature. This article gives the information about the advantages and disadvantages of the centrifugal pump to know more details about it.

Advantages of centrifugal pump :
  • Simple in construction and cheap
  • Steady delivery
  • Handle liquid with a large amount of solid
  • Uniform pressure without shock or pulsation
  • Direct coupling to the motor
  • Maintenance cost is lower 
  • Can be mounted horizontally or vertically
  • No valve involve in pump operation
  • No metal to metal fit 
  • Discharge line may be closed
  • Therein almost no noise 
  • In these pumps, there is no drive seal so there is no leakage in the pump
  • It can pump hazards liquids
  • A pump has almost 100 % efficiency
  • This pump has minimum wear with respect to other
  • This pump is used magnetic coupling which breakup on high load eliminating the risk of damaging the motor
Disadvantages of centrifugal pump :
  • Can not handle viscous fluids efficiently
  • Can handle a small number of gases in liquids
  • Primary offer needed before startup
  • Can not be operated at a high head
  • Must be primed
  • This pump has not effective for high velocity but multistage configuration are expensive
  • Can not be operated at high discharge pressures
  • Maximum efficiency is to be hold over a narrow range of conditions
