Meaning and Definition
A rotary pump with two meshing gears that trap fluid between their teeth and the pump casing, transferring it from the inlet to the outlet.
Refers to a simple, robust, and positive displacement pump known for smooth, non-pulsating flow. It is a fundamental component in hydraulic systems, lubrication systems, and various industrial fluid transfer applications.

- Misspelling as 'geer pump' or 'gearpump' (should be two words).
FAQ
Frequently Asked Questions
No. A gear pump is a positive displacement pump that moves a fixed amount of fluid per revolution. A centrifugal pump is a dynamic pump that uses a rotating impeller to increase fluid velocity and pressure.
They are simple, compact, cost-effective for high-pressure applications, provide smooth flow, and are good for handling viscous fluids.
They are generally not suitable for fluids with suspended solids (which can damage the gears), can be noisy, have fixed flow rates, and are less efficient with low-viscosity fluids compared to other pump types.
Common applications include hydraulic power systems, engine and transmission lubrication systems, fuel oil transfer, chemical dosing, and pumping polymers, resins, or adhesives.
