• There are two primary designs. External gear pumps have two identical gears meshing externally and are very common. Internal gear pumps feature a smaller gear rotating inside a larger one.
• Common materials include cast iron, stainless steel (e.g., 316 SS for corrosion resistance), and aluminum. Critical components often use materials like carbon/ceramic seals, PTFE (for idlers and wear plates), and hardened steels for gears to ensure durability and compatibility with different fluids.
• Gear pumps are excellent for handling fluids with a wide range of viscosities—from thin solvents to thicker oils and lubricants (up to 2500 cP or more as noted in some models).
• Simple, compact design with few moving parts, making them relatively inexpensive and easy to maintain.
• Gear pumps serve diverse industries:Hydraulics Powering machinery like excavators, forklifts, and presses.Lubrication Supplying oil to gears, bearings, and engines.Fuel Transfer Moving diesel, gasoline, and oils. Handling resins, adhesives, solvents, paints.
