How does a
gear pump work?
ATTRIBUTES
Gear pumps work according to the positive displacement principle. The liquid is sucked in on one side and transferred further on the outlet side with constant pressure.
When the gears are driven, a vacuum is created, causing the liquid to be drawn in. The liquid is then conveyed between the housing and the gear wheels. With this principle, the two gears fill each other up with liquid, ensuring uniform pulsation-free pump delivery.
Leakage currents (gap losses) occur between the gear tips and the housing wall.
These depend on the design (precision), temperature and density of the liquid, etc.
