Global Gear Pump Manufacturers

A gear pump is a widely used positive displacement pump that moves fluid by trapping a fixed volume between interlocking gears and mechanically displacing it through the pump casing. From petrochemicals and coatings to food and hydraulic systems, gear pumps have become reliable workhorses wherever steady, metered flow is required

Why gear pumps matter: tight clearances ensure smooth, near-constant output per revolution; the design tolerates a wide viscosity range; and robust construction enables dependable performance at elevated pressures.
