Understanding Internal Gear Pumps

Internal gear pumps operate by utilizing two gears—a rotor and an idler—that mesh together within a housing. This design allows for the absorption and displacement of fluids, making it particularly effective for handling viscous liquids and creating high pressure. The primary characteristics of internal gear pumps include their ability to handle various liquid types, including corrosive and highly viscous substances. Their design ensures a smooth and steady flow, making them ideal for complex industrial processes.

Key Applications of Internal Gear Pumps

Internal gear pumps are commonly employed in numerous applications owing to their versatility. They are extensively used in the chemical industry for transferring solvents and acids, in food processing for flavor additives, and in oil refineries for crude oil transfer. Additionally, they find utility in hydraulic systems due to their reliability and performance under pressure.
