Applications of gear pumps

Introduction

Gear pumps are indispensable components in many industrial applications. They are characterized by their efficiency, reliability and versatility. In this article, we will focus on the applications of gear pumps, in particular external gear pumps, as they are widely used and versatile in numerous industries.

Basics of external gear pumps

Externally toothed gear pumps consist of two gears that are toothed outside their axis and mesh with each other. These gears rotate inside a housing that draws in and transports the liquid. The design and efficient operation make them a preferred choice in many applications.

Applications in the automotive industry

Lubrication of motors

External gear pumps play a crucial role in the lubrication of combustion engines. They ensure that the oil reaches the moving parts of the engine evenly and under constant pressure, which reduces wear and extends the service life of the engine.

Fuel delivery

In the automotive industry, external gear pumps are also used to pump fuel. They ensure an even and continuous flow of fuel from the tank to the engine, which ensures optimum combustion and efficiency.

Applications in the chemical industry

Conveying chemicals

External gear pumps are ideal for pumping chemicals and other aggressive liquids. Their robust design and ability to generate high pressures make them a reliable solution for transporting corrosive and viscous substances.

Dosing and mixing

In the chemical industry, gear pumps are often used for dosing and mixing applications. Their precision and reliability enable accurate control of the amount of liquid, which is crucial for the manufacture of chemical products.

Applications in the food industry

Conveying liquids

External gear pumps are widely used in the food industry, especially for pumping liquids such as oils, syrups and sauces. Their ability to generate even and pulsation-free flows is crucial for the quality and consistency of food products.

Filling systems

In filling systems, external gear pumps ensure that liquids are filled precisely and efficiently into bottles and containers. Their reliability and accuracy are key factors for the efficiency and quality of filling processes.

Applications in hydraulic systems

Hydraulic drives

External gear pumps are often used in hydraulic systems to operate hydraulic drives. They generate the necessary pressure to control hydraulic cylinders and motors used in a variety of machines and devices.

Industrial machines

In industrial machinery, such as presses and injection molding machines, external gear pumps play an important role in providing the hydraulic power required to operate these machines. Their reliability and efficiency contribute to the performance and productivity of the machines.

Advantages of external gear pumps

High efficiency and reliability

External gear pumps offer high efficiency and reliability, making them a preferred choice for many industrial applications. Their ability to produce even and constant fluid flows is a major advantage in many processes.

Simple construction and maintenance

The simple design of external gear pumps facilitates their maintenance and repair. They consist of few moving parts that are easily accessible and replaceable, which reduces operating costs and extends the service life of the pump.

Versatility

The versatility of external gear pumps allows them to be used in a wide range of applications and industries. Their ability to handle different fluids and operating conditions makes them a flexible solution for many challenges.

Maintenance and care of external gear pumps

Regular inspections

Regular inspections are crucial to ensure the proper operation of external gear pumps. By checking seals, gears and bearings, wear and damage can be detected and rectified at an early stage.

Replacement of wearing parts

Replacing wearing parts such as seals and gears is important to maintain the efficiency and reliability of the pump. Regular maintenance and the timely replacement of worn parts can minimize downtimes and extend the service life of the pump.

Lubrication of the components

Regular lubrication of moving parts is crucial to minimize friction and wear. Proper lubrication helps to maintain the performance and efficiency of the pump and prevent overheating.

Conclusion

External gear pumps are indispensable components in many industrial applications. Their efficiency, reliability and versatility make them a preferred choice in the automotive industry, chemical industry, food industry and hydraulic systems. With regular maintenance and care, these pumps can offer a long service life and high performance, making them a valuable investment for any company.
