About External Gear Pumps

External Gear Pumps are a type of positive displacement pump that uses gears to transfer fluids. They are usually made of materials such as cast iron, stainless steel, or other alloys, depending on the application and the type of fluid being pumped. These pumps are widely used in various industrial applications for pumping liquids with a wide range of viscosities. They are commonly used in hydraulic systems, lubrication systems, transfer and metering of fluids, and various industrial processes where a steady flow of liquid is required. External Gear Pumps are suitable for fluids with a wide range of viscosities, from thin oils to thicker liquids.

Superior Material & Customization

Manufactured using IS 210 Gr FG 220 or SS 316, these gear pumps are designed for excellent corrosion resistance and durability. The range is highly customizable, featuring discharge sizes, sealing types, and mounting options to best fit your specific process requirements. This flexibility allows seamless integration into various industrial setups.

Efficient Operation & Versatile Performance

Engineered to handle viscosities up to 1,00,000 cSt and operate at temperatures from -5C to 180C, these pumps maintain high volumetric efficiency and operate quietly due to double helical gears. Their self-lubricated system ensures longevity, making them ideal for continuous and demanding industrial applications such as chemical transfer or oil handling.

FAQ's of External Gear Pumps:

Q: How do I select the correct external gear pump for my application?

A: Consider factors such as fluid viscosity, temperature, required flow rate, operating pressure, and compatibility with materials like IS 210 Gr FG 220 or SS 316. You should also specify the desired connection type, mounting, and sealing options for optimal performance.

Q: What types of fluids can be transferred using these external gear pumps?

A: These pumps efficiently handle a wide spectrum of fluids, including oils, viscous liquids, and chemicals. Thanks to their robust construction and material choices, they are compatible with fluids up to 1,00,000 cSt viscosity and a wide temperature range (-5C to 180C).

Q: Where are these gear pumps typically installed in an industrial environment?

A: They can be foot-mounted or flange-mounted onto base plates, making them suitable for fluid transfer stations, chemical storage facilities, lubricant circulation units, and other process areas requiring reliable, high-efficiency positive displacement pumping.

Q: What is the process for installing and maintaining an external gear pump?

A: Installation involves aligning the gear pump on a stable platform, connecting flanged or threaded inlets/outlets, and ensuring the correct power supply (220V/415V AC). Maintenance is straightforward due to the self-lubricating design, requiring routine inspection of seals, bearings, and periodic cleaning.

Q: When should I choose mechanical seal versus gland packing?

A: Choose a mechanical seal for applications where leakage must be minimized, such as hazardous chemical transfer. Gland packing is suitable for less critical applications or where periodic maintenance can be performed easily.

Q: What are the key benefits of double helical gears in these pumps?

A: Double helical gears significantly reduce noise and vibration during operation while improving volumetric efficiency and extending pump life. This makes the pumps particularly suitable for continuous or noise-sensitive industrial environments.
