What is KNOLL Gear Pump? How does the gear pump work?

KNOLL positive gear pumpA pair of counter-rotating toothed cylinders are used to move fluid between the low pressure inlet and the high pressure outlet. Fluid is trapped in a groove formed between the gear teeth and the pump body until the rotating gear pair reengages the individual components. The reduction in the volume of the meshing gear forces the fluid out through the discharge port. When the gear teeth sweep through the pump housing, a relatively large number of teeth minimizes leakage.
Because a certain amount of fluid is trapped in the gap between the meshing teeth, the gear pump may produce noise. Drain bags are sometimes added to counteract this tendency.
Spur gear pumps are usually equipped with sleeve bearings or bushings that are lubricated by the fluid itself (usually oil). Other fluids that lack oil lubricity often require a more stringent pump design, including positioning the bearing outside the wet chamber and providing a proper seal. Sometimes dry running bearings are used. The use of a simple support shaft (as opposed to the cantilever arrangement seen in many internal gear designs) allows the pump assembly to handle very viscous liquids, such as tar, without worrying about shaft deflection.
