There are three primary
types of hydraulic pumps.
Understanding Hydraulic Pump Designs
Ø The gear pump
Ø The vane pump
Ø The piston pump

Gear Pump
Understanding Hydraulic Pump Designs
Advantages:
Ø Inexpensive
Ø Contamination resistant
Ø High RPM capable
Ø Rotation easily changed
Ø Reliable
Ø Can be stacked together
Disadvantages:
Ø Inefficient
Ø Can be noisy
Ø Quickly become less
efficient with wear and
higher pressure
37. #FluidPowerWebinar
Piston Pumps
Understanding Hydraulic Pump Designs
Advantages:
Ø High to very high
pressure capacity
Ø High RPM
Ø Extremely efficient
Ø Myriad configurations of
compensation
Disadvantages:
Ø Expensive
Ø Contamination sensitive
Ø Most expensive to repair
