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
