Internal Gear Pump

is a type of positive displacement pump that uses two meshing gears — one internal and one external — to move fluid with smooth, continuous flow. It features:

• A central internal gear

• An external gear rotating partially inside the internal gear

• A crescent-shaped spacer to guide the liquid

Key advantages include:

• Low-pulsation, steady flow

• Excellent for high-viscosity fluids

• Quiet operation and high efficiency

Commonly used in chemical processing, food production, lubrication systems, and fuel transfer applications requiring gentle and precise pumping.
