gear pump

[′gir ‚pəmp]
(mechanical engineering)
A rotary pump in which two meshing gear wheels contrarotate so that the fluid is entrained on one side and discharged on the other.

Gear Pump

 

a rotary pump with gears as working members. Involute straight-cut, helical, or herringbone gears are ordinarily used. Such pumps are simple in design, compact, and reliable. Their output ranges from 0.25 to 40 cu m per hr at pressures up to 3 meganewtons per m2 (30 kg-force per cm2). Gear pumps are used mainly for circulating petroleum products in machine lubrication systems and in hydraulic drive mechanisms.

gear pump

gear pump
Gear pump.
A high-pressure pump used in hydraulic, oil, and fuel systems. The fluid is pressurized when it passes between the teeth of a gear and radiused case of the pump. It is a constant displacement-type pump whose output is varied by spilling the pump output fluid back into the pump inlet.
