What is a Rotary Gear Pump?
Rotary gear pump is a type of positive pump that is used to transport fluids from one place to another. This pump works on the principle of positive displacement, where two gears or gears rotate in a casing or housing. There are two types of teeth in a rotary gear pump: driver gear and driven gear.
When gears rotate, they create space between the teeth. Liquid is sucked into this chamber through the pump inlet, and with further rotation, the liquid is forced out through the outlet. This working principle produces stable fluid flow and precision in fluid transfer.
Rotary gear pumps are an excellent choice for transporting fluids with high viscosity and stable pressure. They can also handle fluids that have a limited number of solid particles. These pumps have many applications in various industrial sectors, including oil and gas, chemical, food and beverage, pharmaceutical and many more. Its main advantages are efficiency, precision in fluid dosing, and the ability to handle a wide range of fluid transfer conditions.
Working Principle of Rotary Gear Pump
Rotary gear pumps work on the basic principle of positive displacement. This pump consists of two gears or gears that rotate in a housing or casing. One tooth is called the driver gear, and the other is the driven gear. When gears rotate, they create space between the teeth. Liquid is sucked into this chamber through the pump inlet, and with further rotation, the liquid is forced out through the outlet.
The advantage of this working principle is the ability of the rotary gear pump to transport liquids with high viscosity and stable pressure. They also allow for consistent flow and precision in fluid transfer.
Types of Rotary Gear Pumps
There are several types of rotary gear pumps, including:
- External Gear Pump: This type has two external gears that rotate outside the casing. This is the most commonly used type.
- Internal Gear Pump: Here, one external and one internal gear rotates together. Internal gears are usually smaller than external gears.
- Gerotor Pump: Gerotor pump has an internal rotor that rotates within an external rotor. This is the type often used in automotive applications.
- Crescent Gear Pump: This type has one crescent or crescent gear which is used to remove shrinkage from the external gears. This makes this pump suitable for fluids that have high viscosity.
Rotary Gear Pump Function
Rotary gear pumps have several main functions in various industrial sectors. Some of its main functions include:
- Fluid Transfer: The main function of a rotary gear pump is to transport fluids from one place to another. They can be used for the transfer of fluids with a wide range of viscosities, including very viscous fluids such as heavy oils, lubricants, and fluids with a limited amount of solid particles.
- Fuel Supply: In the automotive and maritime industries, rotary gear pumps are used to supply fuel to engines, although they are also used in the aviation industry.
- Transfer of Chemicals: Rotary gear pumps are suitable for the transfer of chemicals, including those that are corrosive and dangerous, so they are used in the chemical industry.
- Uses in Pharmaceutical Industry: They are used in the production of drugs and pharmaceutical products to transport active chemicals and various fluids used in pharmaceutical processes.
- Food and Beverage Industry: In this industry, rotary gear pumps are used in transferring liquid food ingredients such as syrup, vegetable oil and liquid chocolate.
- Maritime Industry: Rotary gear pumps are used in ships for the transfer of fuel, lubricants, and various other fluids.
- Water Treatment Industry: In water purification and water treatment plants, they are used to control precipitating chemicals and disinfectants.
- Oil and Gas Industry: They are used in the transfer of petroleum, fuels, and petrochemical products.
- Pulp and Paper Industry: Rotary gear pumps are used for the transfer of pulp and various fluids used in the pulp and paper industry.
- Manufacturing Industry: Used in various manufacturing and production processes.
- Water Treatment Industry: They are used in water treatment plants to control precipitating chemicals and disinfectants.
Selling Rotary Gear Pumps
The gear pump functions to drain the liquid which is normally used for fluid use. Gear pumps are usually used to convey fluids with low viscosity such as alcohol, solvents or liquefied gases.
Fluids with high viscosity such as fabric paints, polymers, and liquid rubber can also be circulated using a gear pump.
