Gear pump

A continuous-flow positive-displacement pump using meshing gears. Common in larger commercial espresso machines and brewers where smooth, quiet, low-pulsation flow is needed.

Category: Pumps & Pressure

A type of positive displacement pump using meshing gears to move water at constant volume per rotation. Smoother and quieter than vibration pumps; usually slower than rotary vane pumps.

Why it matters — Gear pumps deliver very smooth, pulse-free flow — useful for flow-profiling machines where the barista needs precise control. Their consistency makes them popular in some high-end espresso designs.

Good to know

Gear pumps are used in some Decent and Sanremo machines.
Less common than vibration or rotary pumps, but the smooth output is genuinely noticeable when comparing machines.
