How a Vacuum Pump Creates a Vacuum

The vacuum pump helps us in many situations. It is used in many industrial and commercial applications, such as pumps, compressors and other pneumatic devices. This article describes how a vacuum pump creates the vacuum that it works with.

The machine can remove dirt and dust from virtually anything, from floor stones to porcelain enamel. Here are a few facts about a commercial vacuum system: To understand more about a commercial vacuum system, we’ll do a deep cleaning by removing old paint that coats the wall and ceiling. This will simulate a real problem, not an advantage of the commercial system. Here’s a commercial Dyson vacuum cleaner to help understand the core components of a commercial cleaning machine: Here’s the installation step-by-step for a commercial Dyson residential cleaning system: Pump your vacuum through a few passes, cleaning completely around the artifact: If successful, rinse thoroughly by draining the reservoir through the hose. 

Some systems use a suction cup, where the hose connects into the vacuum cup feeder on the other side of the room. The suction cup is easy to use when the hose is extended as high as it goes. This will give you another opportunity to clean the artifact while the pump powers down: Take this opportunity to clean around the exterior of the debris. This will help loosen spots of dust trapped inside. This is one of many essential steps of a commercial cleaning system including draining the reservoir, cleaning the surrounding surfaces, and rinsing. This should be retrospective of the entire cleaning process.

Schematic of a typical high vacuum pump is shown below:

While vacuum cleaners are generally heavily automated, there are few if any that are easy to use manually. Manual vacuums, although they might cost a little more to acquire, are much more efficient and produce less waste in comparison to a computerized cleaning system. A drawback sometimes encountered with manuals is their requirement to have a good understanding of the vacuum’s operation and precise timing requirements. These may be a bit out of the reach of most home users.

One of the common features found in most vacuum cleaners is some form of automatic sensor. These sensors come in the form of a proximity sensor and a pressure sensor, among many other electronic components. When these sensors detect that the vacuum chamber is empty or that there is insufficient vacuum being created, the vacuum system is triggered to start cleaning.

These sensors detect vacuum in two ways. First, it calculates the distance that the vacuum cleaner has traversed through the space, reporting that distance in units of millimeters (mm) (e.g., 5 mm = 1/64 inch — this measurement is called “dia”). Second, the vacuum cleaner will cycle the brush to clean the space between the particle and the material with highest density.

Although this ultrasonic cleaning process is fast, it leaves a layer of dust behind. Dust trapped inside the vacuum cleaner can be an environmental concern. While dust is generally considered a minor part of the overall waste stream of a vacuum cleaner, it is an unwanted byproduct that can adversely affect its performance.

Depending on the vacuum cleaner’s type, most emitters have a HEPA filter to filter out potentially harmful particles and airborne pollutants while cleaning. PC fans or blowers might be used to extract air for cleaning. Although vacuum fans can also process air without a filter, they generate more noise and require some sort of PWM motor to spin them quickly enough.

Examples of less known motors include the DC Powered 8X31 vacuum cleaner from Dyson or the Orbitron 12710 gutter vac.

Traditional vacuum cleaners use typically a single phase, high-efficiency electromagnets to generate suction. These magnets favor a fast, robust cleaning motion, when compared with slower, more angular impellers. Modern higher-efficiency electromagnets can produce clean points over twice as fast and are more energy efficient. Depending on the type of vacuum cleaner, the electric current in the motors can also govern the way that the vacuum is shaped to create a clean seal (i.e., circular vs. elliptical).

It’s actually a series of fans. The action of the fans provides power to the pump and makes the pump spin at its maximum speed.

A video explaining the operation of a vacuum pump is shown below. The video is from Patheos.com This video is quite pertinent especially to people that don’t understand the function of a vacuum pump:

In summary a vacuum pump removes air or other gasses out of a chamber to fill a container with a substance that can be compressed (like water or air) and transported to another location. A vacuum pump can be either internal or external in its operation. Here are three simple diagrams explaining the functionality of each kind of vacuum pump:

Internal vacuum pumps work by filling a chamber with air. This requires three parts: the pump itself, the chamber to fill, and the container to receive the compressed air. The chamber to fill is called the compressor; for those that are familiar with a car muffler, it is typically located adjacent to the intake, near the air filter. Along with the chamber, there is the hose that leads to the outside.


A typical internal vacuum pump is composed of a pump, a compressor (containing the air supply and extractor), a power source (lights and/or motors), and a hose connected to the compressor through a central reservoir. A typical adapter allows for the hose to be connected to other types of pumps.examples: the hose connects to a water pump, which distributes water through a kitchen dishwasher for example, or to a gas water heater.

External vacuum pumps work in the same way but with external variations. Those that can fit a wide range of vacuum requirements (e.g. 36 volts DC, 20,000 PSI, higher power, etc.), and can transport a liquid or gas outside as well as inside a container.examples: Large booms, helicopter pumps (to remove bubbles or create suction), gas generator pumps that heat water for washing.

The pump requires – there are many different types to meet specific needs. Boreless shorting-block pumps are made to many be used in combination with a diaphragm to lower the vacuum in a vacuum pump. You might have already encountered these in residential breakers or gas pressure washers.
