Description
Product details
Internal Gear Pumps are positive displacement pumps widely used for transferring fluids in hydraulic and lubrication systems. Their design, featuring intermeshing gears within a compact housing, ensures smooth and efficient fluid flow. Known for their quiet operation, high efficiency, and ability to handle a wide range of viscosities, internal gear pumps are suitable for diverse industrial and mobile applications. Key Features of Internal Gear Pumps Compact and Simple Design: Consists of two gears: a larger outer gear (ring gear) and a smaller inner gear (idler gear) that rotate within a single housing. Smooth and Quiet Operation: The design minimizes pulsation, ensuring steady flow and low noise levels. Wide Viscosity Range: Capable of handling both low- and high-viscosity fluids, including oils, fuels, and viscous chemicals. Self-Priming Capability: Efficiently draws fluid into the pump without the need for external priming. High Volumetric Efficiency: Provides consistent flow rates with minimal internal leakage. Bidirectional Operation: Can handle fluid flow in both directions, offering flexibility in system design. Durability: Built to withstand harsh operating conditions, with options for corrosion-resistant materials. Operating Principle Internal gear pumps operate by creating a vacuum as the gears rotate. The smaller idler gear is offset within the larger ring gear. Fluid enters the pump through the inlet port as the gears unmesh, filling the void. The gears then mesh together, pushing the fluid through the outlet port. This continuous meshing and unmeshing action ensure smooth and consistent flow. Advantages of Internal Gear Pumps Versatility: Suitable for a wide range of fluids, including abrasive, corrosive, and viscous liquids. Quiet Performance: Low pulsation and vibration make them ideal for noise-sensitive applications. Compact Size: Easy to integrate into systems with limited space. Reliable Performance: High efficiency and consistent flow rates over a wide pressure range. Ease of Maintenance: Simple design allows for easy disassembly and cleaning. Applications Hydraulic Systems: Used in industrial and mobile machinery for precise fluid transfer. Lubrication Systems: Pumps oil in compressors, turbines, and engines. Chemical Processing: Handles viscous chemicals, resins, and polymers. Food and Beverage Industry: Transfers syrups, oils, and other food-grade fluids. Marine Systems: Used in fuel transfer and bilge pumping. Bitumen and Asphalt Handling: Ideal for high-viscosity applications.
