They are not suitable for materials containing solids because they can cause premature wear. Internal gear pumps are self-priming and can be used in low NPSH applications. They usually provide smooth, continuous flow. In theory, at least they are bidirectional. They can provide individual or combined fluid power systems in series design.
Internal gear pumps have a wide range of applications in many industries: food manufacturers use them to deliver thick pastes and seasonings; the petrochemical industry deploys them in high-pressure metering applications, and engine manufacturers use them for oil transportation. They are used as delivery pumps. Special designs can be used for aerospace applications. The hydraulic pump will meet SAE bolt hole requirements.
In the early 1990s, automobile engine manufacturers switched from external gear pumps to internal gear designs, including... less
