The Main Types & Applications of Vacuum Pumps

Regardless of the industry, certain types of vacuum pumps are commonly used. Many industries today still use mechanical pumps as their main source of vacuum power. A blower is often used with a mechanical pump to create even stronger suction.

Busch Vacuum has a wide range of different types of vacuum pumps used in many industries. If you’re looking for a certain type of vacuum pump for your business, you should definitely check out their selection. In this article, we will explore the different types of vacuum pumps that are available on the market today and their various applications.

The five types of vacuum pumps include:

1. Rotary Vane Vacuum Pumps

Rotary vane vacuum pumps are the most common type of mechanical pump used in industry today. They work by using a rotating van to pump out the air from a sealed chamber. This vacuum pump is often used with a blower to create an even stronger suction. Most oenologists use rotary vane vacuum pumps in wine production to remove oxygen from the wine without damaging the flavor.

2. Diaphragm Vacuum Pumps

Diaphragm vacuum pumps use a flexible diaphragm to pump out the air from a sealed chamber. This type of pump is often used in the food and beverage industry because it doesn’t require oil for lubrication. This makes them ideal for applications where there is a risk of contamination. Aside from the food and beverage industry, diaphragm pumps are also used in the medical industry for applications such as vacuum-assisted delivery and suctioning.

3. Liquid Ring Vacuum Pumps

Liquid ring vacuum pumps use a rotating impeller to pump out the air from a sealed chamber. This type of pump is often used in the paper and pulp industry because it can handle large volumes of gas without requiring a lot of maintenance. Liquid ring pumps are also used in the petrochemical industry for distillation and vacuum drying applications.

4. Scroll Vacuum Pumps

Scroll vacuum pumps work by using two interlocking scrolls to pump out the air from a sealed chamber. This type of pump is often used in the semiconductor industry because it can create a very high vacuum level without requiring much power. Scroll pumps are also used in the medical industry for applications such as MRI machines and CT scanners.

5. Turbomolecular Vacuum Pumps

Turbomolecular vacuum pumps are the most common type of high-vacuum pump. They work by using a series of rotating blades to create a “turbine” effect, which sucks in gas molecules and traps them inside the pump. These pumps are very efficient at pumping away large volumes of gas, but they have a limited range and cannot achieve ultra-high vacuums.

Turbomolecular pumps are typically used in conjunction with other types of pumps, such as roughing pumps, to create a high-vacuum system. Roughing pumps remove most of the gas from a system, while turbomolecular pumps take care of the “fine-tuning.”

There are five types of vacuum pumps commonly used in industry: rotary vane, diaphragm, liquid ring, scroll, and turbomolecular. Each type of pump has its unique set of advantages and disadvantages, making them well-suited for certain applications. If you’re looking for a specific type of vacuum pump for your business, you should definitely check out the different available options.
