Based on the basics, which do you think a centrifugal / Positive Displacement pump can be used in? 

Question 2. Share application advantages/ disadvantages for the Centrifugal Pump or Positive Displacement. 

If you want to challenge yourself, you can provide both. ]]> 2021-10-04 13:54:04 UTC https://padlet.com/mubzlaren/dvc31sbd7z58nbvf/wish/1789700318 Kelly: Pump Operations kellyeajl https://padlet.com/mubzlaren/dvc31sbd7z58nbvf/wish/1803483330 1. Positive displacement pump can be used for chocolate processing plant, where thick paste is involved. 

2. Positive displacement pump can be used for high pressure low flow application. The have less frictional losses and can deliver constant pressure as they have dampeners.]]> 2021-10-09 00:46:31 UTC https://padlet.com/mubzlaren/dvc31sbd7z58nbvf/wish/1803483330 Darren https://padlet.com/mubzlaren/dvc31sbd7z58nbvf/wish/1803488453 1. Centrifugal pup is used in water delivery systems which is fairly clean, such as irrigation, fire or cooling water applications  2. Positive displacement pump are good for constant flow even as pressure varies. However, i think positive displacement pump cost more in the market bcoz of its abilies]]> 2021-10-09 00:53:16 UTC https://padlet.com/mubzlaren/dvc31sbd7z58nbvf/wish/1803488453 Chris chriscfs13 https://padlet.com/mubzlaren/dvc31sbd7z58nbvf/wish/1804755524 1.  I think the positive displacement pump can be in applications where you want to see accurate dosing or high pressure output is required.  Applications like pumping low viscosity fluids, paint spraying, oil production and high force washing eg car wash chamber.

2. 
a) For positive displacement (PD) pump, it can be used for high force application eg >700 bar, whereas centrifugal pump has low force pressure around 20 bar.
b) PD pump can maintain constant flow even when the system pressure of the pump is varying.
c) PD pump can handle a variety of fluid type eg high, low and variable viscosity whereas centrifugal pump is used for relatively high viscosity fluid.]]> 2021-10-10 01:52:07 UTC https://padlet.com/mubzlaren/dvc31sbd7z58nbvf/wish/1804755524 Would like to thank all of you for your interaction / response and feedback!
