Advantages

Extremely high pressures

 

Flow can be easily controlled via speed

 

Pressure changes do not impact flow rate or pump balance

 

Piston pumps can tolerate entrained gas

 

Stainless versions for FDA approval

 

Air operation in very low stroke rates will tolerate high viscositiesP

Disadvantages

Positive inlet feed pressures required with higher speeds / viscosities

 

Wear extremely quickly with abrasive fluids if speeds are not kept very low

 

Usually limited to clean thin liquids above 50 strokes / minute
