An exploded view of an external gear pump Fluid flow in an external gear pump Fluid flows from left to right in this internal gear pump. Oil pump from a scooter engine. A gear pump uses the meshing of gears to pump fluid by displacement. [1] They are one of the most common types of pumps for hydraulic fluid power applications.
Fluid flow in an external gear pump. A hydraulic pump is a mechanical source of power that converts mechanical power into hydraulic energy (hydrostatic energy i.e. flow, pressure). Hydraulic pumps are used in hydraulic drive systems and can be hydrostatic or hydrodynamic. They generate flow with enough power to overcome pressure induced by a ...
A positive-displacement pump operates by forcing a fixed volume of fluid from inlet pressure section of the pump into the discharge zone of the pump. It can be classified into two types: Rotary-type positive-displacement pumps: Internal gear pumps; Screw pumps; Reciprocating-type positive-displacement pumps: Piston pumps; Diaphragm pumps
Rotary-type positive displacement: internal and external gear pump, screw pump, lobe pump, shuttle block, flexible vane and sliding vane, circumferential piston, flexible impeller, helical twisted roots (e.g. the Wendelkolben pump) and liquid-ring pumps; Reciprocating-type positive displacement: piston pumps, plunger pumps and diaphragm pumps
The type of pump used varies. Gear pumps [1] [2] trochoid pumps [3] and vane pumps [a] are all commonly used. Plunger pumps have been used in the past, but these are now only used rarely, for small engines. To avoid the need for priming, the pump is always mounted low-down, either submerged or around the level of the oil in the sump. A short ...
These men were all working to perfect an internal gear mechanism by a one-tooth difference to provide displacement. Myron Hill made his first efforts in 1906, then in 1921, gave his entire time to developing the gerotor.
