Industrial Vacuum Pumps – Applications & Types

Industrial vacuum pumps are considered the “heart” of industries ranging from manufacturing, processing, and packaging of food and pharmaceuticals to electronics. Vacuum pumps help remove air, moisture, and other gases to create a vacuum environment, ensuring products maintain the highest quality. Below, Tân Long provides detailed information on common applications and the operating principles of vacuum pumps.

 

What is an Industrial Vacuum Pump?

An industrial vacuum pump is a device used to remove air and gases, including water vapor, from a sealed space to create a vacuum or partial vacuum. Vacuum pumps are widely used in many industries, such as manufacturing, processing, and food packaging, where high standards of quality and safety are required.

Operating Principle of Vacuum Pumps

Different types of vacuum pumps operate based on different principles. Fundamentally, industrial vacuum pumps create a pressure difference between two environments:

Vacuum creation stage:

• When the pump starts, its rotor or impeller continuously rotates to draw air or vapor out of the chamber (the area to be vacuumed).

• Air and vapor molecules are sucked into the pump chamber through the inlet valve.

Compression stage:

• Once inside the pump chamber, the molecules are compressed or moved through internal components (depending on the pump type), such as vanes (in vane pumps) or rotors (in screw pumps).

• At this stage, the gas molecules are compressed, and their pressure becomes higher than the atmospheric pressure.

Exhaust stage:

• Compressed gas molecules are expelled from the pump through the exhaust valve.

• This process creates a pressure difference between the inside chamber and the external environment, forming a vacuum inside the chamber.

Common Types of Industrial Vacuum Pumps

There are various vacuum pump models on the market, each suited for specific industrial applications. Below are the most common types:

Oil-sealed rotary vane vacuum pumps

• Operating principle: Vanes rotate inside an oil-filled chamber. The oil cools, separates water, seals gaps, and lubricates the pump.

• Advantages: High vacuum capability, quiet operation, durable.

• Applications:

  • Healthcare and laboratories

  • Vacuum packaging

  • Electronics

  • Food packaging

  • Printing

  • Plastics, CNC, molding

Water-sealed vacuum pumps

• Operating principle: The pump contains a certain amount of water or liquid during operation. As the impeller rotates, water forms an eccentric ring along the chamber wall. This water ring creates variable-volume chambers that draw in, compress, and expel air.

• Advantages: Resistant to humid air, vapor, and dust. Durable in harsh environments, long lifespan, low maintenance.

• Applications:

  • Chemical plants

  • Paper industry

  • Textile dyeing

  • Wastewater treatment

• Reference: Bơm chân không Travaini (Ý), officially distributed by Tân Long.

Piston vacuum pumps

• Operating principle: The piston moves within a cylinder, creating vacuum chambers that draw in air, compress it, and expel it.

• Advantages: Produces deep vacuum and strong suction.

• Applications:

  • Research laboratories

  • Aerospace

  • Special material production

Screw vacuum pumps

• Operating principle: Two screw rotors rotate in opposite directions. Air is trapped in the screw grooves, gradually compressed, and expelled.

• Advantages: High efficiency, energy-saving, clean operation, environmentally friendly.

• Applications:

  • Food, pharmaceutical, and electronics industries

  • Large-scale factories

  • Automated production lines

  • Continuous operation environments

Conclusion

Industrial vacuum pumps have become indispensable in many sectors, including food, chemicals, textiles, pharmaceuticals, healthcare, electronics, and environmental treatment. Understanding the operating principles and features of each pump type helps businesses select the right equipment, optimize investment costs, and improve long-term operational efficiency.
