The gear pump cannot match the pressure generated by the reciprocating pump or the flow rate of the centrifugal pump, but it has higher pressure and throughput than the vane pump or vane pump. Internal gear pumps have better suction capacity than external gear designs, and although applicable from 1 cP to more than 1,000,000 cP, they are more suitable for high viscosity fluids.
Because the output is proportional to the speed, internal gear pumps are commonly used for metering and mixing operations. The small internal volume allows reliable measurement of the liquid flowing through the pump, enabling precise flow control.
Internal gear pumps can be designed to handle corrosive liquids. Although they are usually made of cast iron or stainless steel, new alloys and composite materials enable the pump to handle corrosive liquids such as sulfuric acid, sodium hypochlorite, ferric chloride, and sodium hydroxide.
