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.
