Internal Gear Pumps
Internal gear pumps are positive displacement pumps designed for handling liquids where consistent flow, strong suction capability, and reliable performance are required.
The pump operates using two rotating gears that trap fluid between the gear teeth and pump casing. As the gears rotate, the fluid is transported from the suction port to the discharge port, producing steady and controlled flow regardless of pressure fluctuations.
This design makes internal gear pumps highly suitable for transferring viscous, lubricating, or sensitive fluids across many industrial processes.
Key Features
Internal gear pumps are widely used due to their robust design and operational advantages:
- Smooth and pulse-free fluid transfer
- Excellent performance with high-viscosity liquids
- Strong suction capability and self-priming operation
- Quiet and stable operation
- High volumetric efficiency
- Compact and durable construction
- Long service life with proper maintenance
Typical Industrial Applications
Internal gear pumps are commonly used to transfer:
- Diesel and fuel oils
- Lubricating oils
- Hydraulic oils
- Citumen and asphalt
- Chemical additives
- Resins and polymers
- Solvents and coatings
- Paints and inks
- Chocolate, syrups and food oils
- These pumps are particularly effective when handling viscous or shear-sensitive fluids that require controlled flow.
Industries Using Internal Gear Pumps
Internal gear pumps are widely installed across many industrial sectors including:
- Oil & Gas facilities
- Chemical processing plants
- Mining operations
- Food and beverage manufacturing
- Marine fuel transfer systems
- Power generation plants
- Industrial manufacturing facilities
- Bulk liquid transfer systems
- Their ability to provide consistent volumetric flow makes them suitable for both process systems and transfer applications.
