Gear Pump
A
gear pump is a positive displacement rotary pump which is used to
transport high pressure and high volume flows. It uses step down gearbox
mechanism for pumping various viscous liquids. Mostly used in hydraulic
pumps and engine oil pumps, a gear pump supplies constant amount of
fluid per revolution.
How does a gear pump works?
A gear pump functions through the use of two or more internal gears
that create vacuum pressure, propelling the fluid media. It consists of
two toothed gears that are meshed together in a very tight enclosure. As
each tooth of the gear comes in contact, the load moves to the next
tooth and this will force out the liquid in the discharge pipe.
Types of Gear Pump:
- Internal gear pump : Internal gear pumps are suited for a
wide range of viscosity applications because of their relatively low
speeds. This is especially true where suction conditions call for a
pump with minimal inlet pressure requirements.
- External gear pumps : External gear pumps are a popular
pumping principle and are often found in lubrication pumps in
machine tools, in fluid power transfer units and as oil pumps in
engines.
Applications of Gear Pump:
Gear Pumps are used in a variety of industries and applications. They
are as follows:
