Write short note on Features of gear pump.
1 Answer

Gear pumps are a type of positive displacement pumps i.e. they provide a fixed flow rate regardless of pressure changes within the system.

These pumps are used in a variety of applications across many industries as they are strong and rigid in addition to being built to tight tolerances. They can pump viscous liquids at higher pressures than centrifugal pumps.

They are very commonly used in lubrication pumps for power transmissions in automobiles, heavy trucks, lawn care equipment, hydraulic lifts, and other machine tools.  Your car’s oil pump is likely a gear pump.

Gear pumps are excellent as metering pumps since they can control volume and flow rate of a variety of fluids.  For example, chemical additive metering.
