KNOLL gear pumpCompact and simple structure, limited number of moving parts. They cannot match the pressure generated by a reciprocating pump or the flow rate of a centrifugal pump, but provide higher pressure and throughput than a vane or CAM pump. Gear pumps are especially suitable for pumping oil and other high viscosity fluids.

In both designs, the external gear pump is able to withstand higher pressures (up to 3,000 psi) and flow rates because the shaft support is more robust and tolerances are smaller. Internal gear pumps have better suction capacity and are suitable for high viscosity fluids, although their useful operating range is from 1cP to over 1,000,000cP. Since the output is proportional to the speed, gear pumps are often used for metering and mixing operations. Gear pumps can be designed to handle corrosive liquids. While they are typically made of cast iron or stainless steel, new alloys and composites enable pumps to handle corrosive liquids such as sulfuric acid, sodium hypochlorite, ferric chloride and sodium hydroxide.

External gear pumps can also be used in hydraulic power applications, commonly used in vehicles, lifting machinery and mobile plant equipment. The gear pump is driven in reverse, using oil drawn from elsewhere in the system (usually by a series pump in the engine) to produce a hydraulic motor. This is especially useful for powering areas where electrical equipment is bulky, expensive, or inconvenient. For example, tractors rely on an engine-driven external gear pump to power their services.

KNOLL gear pumps use the action of rotating gears or gears to transport fluid. The rotating element forms a liquid seal with the pump housing and creates suction at the pump inlet. The fluid in the suction pump is enclosed in the cavity of its rotating gear and transferred to the discharge port.
