Oil Gear Pumps
(Gear pump) A gear pump uses the meshing of gears to pump fluid by displacement. They are one of the most common types of pumps for hydraulic fluid power applications. Gear pumps are also widely used in chemical installations to pump fluid with a certain viscosity.
(Gear pump) A small pump consisting of a casing enclosing a driven gear wheel in mesh with a second gear wheel, the fluid being carried from the suction to the delivery side of the pump in the spaces between the teeth.
(Gear Pump) Gear Pumps are used for some engine oil pumps and hydraulic pumps. The concept involves generating oil flow by two gears meshing together in a relatively tight enclosure. The size of the gears and the tightness of the enclosure will determine what the pump is capable of generating.
