Gear pumps can handle a wide range of substances with different properties. Some of the substances that can be pumped by gear pumps include:
- Liquids: Gear pumps are commonly used for pumping liquids such as water, oils (including lubricating oils, hydraulic oils, and fuel oils), solvents, chemicals, paints, inks, adhesives, resins, detergents, and liquid food products (like syrup, molasses, and chocolate).
- Viscous fluids: Gear pumps excel at pumping viscous fluids. They can handle substances like heavy oils, grease, bitumen, asphalt, molasses, honey, syrups, and various polymers.
- Abrasive slurries: Some gear pumps are designed to handle abrasive slurries, such as those containing sand, cement, coal dust, or mineral ores. These pumps often have hardened or specially coated gears and casings to withstand the abrasive particles.
- High-temperature fluids: Gear pumps can handle fluids at elevated temperatures, making them suitable for applications involving hot oils, bitumen, molten plastics, and other high-temperature liquids.
- Corrosive substances: Depending on the materials of construction, gear pumps can handle corrosive substances like acids, alkalis, and other aggressive chemicals. Pumps made from corrosion-resistant materials like stainless steel or specialty alloys are used for such applications.
- Food and pharmaceutical products: Gear pumps are also utilized in the food and pharmaceutical industries to pump various ingredients, flavors, additives, creams, gels, and viscous products like toothpaste and cosmetics.
- Slurries and suspensions: Gear pumps can handle certain slurries and suspensions, including those containing small solid particles, pigments, or additives.
It’s important to note that while gear pumps can handle a wide range of substances, the specific design and materials of construction may vary depending on the intended application and the properties of the pumped medium. It’s always recommended to consult the manufacturer’s guidelines and select a pump suitable for the specific substance and operating conditions.
