Definition and history of gear pumps
A gear pump is a subtype of the positive displacement pump. It is used either for pumping liquids or for power-transmitting drive of hydraulic motors (hydraulic gear pumps). The gear pump was probably invented by Johannes Kepler in 1604. Probably to supply fountains and fountains with water continuously. A gear pump always delivers the medium to be pumped evenly and can withstand pressures of up to 400 bar (high-pressure gear pumps). Also in chemistry (chemical gear pumps) or in matters of highest accuracy (precision gear pumps) gear pumps are used, however there are also more special productions like e.g. polymer gear pumps, hydro gear pumps, stainless steel gear pumps, internal gear pumps or magnetic gear pumps.
structure and types
Each gear pump system consists of 3 components: the housing with inlet and outlet and 2 gears (one of which is driven). Depending on the arrangement and size of the gears used, a distinction is made between external gear pumps, internal gear pumps, annular gear pumps and screw pumps. The external gear pumps have involute toothing and thus transport the medium to be pumped between their teeth and their housings.
External gear pumps
The external gear pumps have a simple design and are therefore inexpensive. Gear pumps are used, for example, as drive means for hydraulic motors in machines (construction machinery, tractors, etc.), as circulation pumps for cooling circuits, as oil pumps in internal combustion engines of cars and as feed pumps for highly viscous liquids.
