Internal gear pumps are versatile and have an effective working viscosity range from 1 cP to 1,000,000 cP. They are commonly used for thin liquids such as water, solvents and fuel oils, but are good at pumping thick liquids such as asphalt, chocolate and adhesives. Internal gear pumps also have a wide operating temperature range (up to 400 ° C), making them suitable for pumping difficult fluids such as tar and molten sulfur.

Some typical applications exemplified by Chinese internal gear pump manufacturer, supplier & Zhejiang Yongling Hydraulic Machinery Co., Ltd .:

Fuel and lubricants

Resins and polymers

Alcohol and solvents

Asphalt, bitumen and tar

Polyurethane foam (isocyanates and polyols)

Food such as corn syrup, chocolate and peanut butter

Paints, inks and pigments

Soaps and surfactants

Ethylene glycol
