The gear pumps belong to the group of positive displacement, rotary piston pumps, which produce flow by transporting the fluid betweenthe teeth of two coupled gears.
The gear pumps belong to the group of positive displacement, rotary piston pumps, which produce flow by transporting the fluid betweenthe teeth of two coupled gears.
One of them is driven by the shaft of the pump (driving shaft), which turns the other one. The gear pumpoperates by the displacement principle - a pinion is driven and rotates the other one in the opposite direction. The filled teeth transport theliquid along the housing wall into the drive chamber.
In the intake chamber, the meshing pinions transport the liquid out of the teeth andprevent the liquid from flowing back. The most important application of this type of pumps includes oleodynamic systems, since they canwork with both low and high viscosity fluids. This type of pumps is only suitable for transporting fluids with no solid particles.
