Gear pumps are commonly used for transferring:
Lubricating oils (e.g., machinery oil, hydraulic oil, engine oil)
Fuels (e.g., diesel, heavy oil, light oil)
Chemical liquids (e.g., resin, paint, additives)
Food-grade liquids (e.g., syrup, chocolate paste, vegetable oil) — requires a stainless steel food-grade gear pump
Polymers and viscous materials (e.g., glue, bitumen)
