Gear pumps are a positive displacement pump which moves the liquid by repeatedly enclosing a fixed volume using interlocking gears, therefore transferring it mechanically using a cyclic pumping action. Gear pumps deliver a smooth and pulse free flow.

The pair of gears create a vacuum on the priming side of the pump, drawing the fluids into the pump chamber the fluid is displaced as the gears turn and interlock. Gears pumps provide high pressure, smooth pulse free flow, and are ideal for low flow rates. Gear pumps are available in a range of materials including cast and stainless steel gears, making them suitable for many applications.
