Gear pumps cannot match the pressure generated by reciprocating pumps or the flow rate of centrifugal pumps, but they have higher pressure and throughput than vane pumps or lobe pumps. Internal gear pumps have better suction capacity than external gear designs, and although the applicable range is from 1 cP to more than 1,000,000 cP, they are more suitable for high viscosity fluids.
  
  Since output is proportional to speed, internal gear pumps are usually used for metering and mixing operations. The internal volume is small, and the liquid flowing through the pump can be reliably measured to achieve 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 pumps to handle corrosive liquids such as sulfuric acid, sodium hypochlorite, iron chloride and sodium hydroxide.
