A vacuum pump, also called a suction pump, is a powerful piece of equipment often seen in manufacturing processes or engineering used to pull air and gas molecules from enclosed spaces to create what construes as a “partial vacuum.”
The industrial vacuum pump can also be used to transfer liquid from one place to the other in the same context as a conventional pump. A priority is to keep the component adequately maintained and replace these as soon as they develop a flaw. Let’s look at the different types of vacuum pumps and how these operate.
What as a Vacuum Pump?
A vacuum pump is also referred to as a suction pump. These can be either wet or dry, meaning lubricated with oil or not. With oil, the gas will be exposed to this during the compression process.
Each has its own pros and cons, with the dry pump having a reduced chance for contaminants while the wet variation, with its lubricating and sealing qualities, is as effective. A range of pumps exists, each most suitable for a particular application. The types include:
- Liquid ring
- Rotary vane
Let’s look at the four primary vacuum pump types in more detail.
At intake, the model expands but will reduce cavity size at the discharge stage, allowing a consistent, moderate vacuum flow. When a steady speed is a requirement, these will serve the purpose most readily.

These are also called “kinetic” pumps with a rotating feature responsible for propelling the gasses and air from the entry point to the discharge.
In this process, a low-pressure area is created that a powerful valve ultimately seals once it transitions to a vacuum. With some models, high-speed fluid jets are used for the process.
These come in two types, either regenerative or centrifugal. Regenerative, or peripheral or turbine, relies on “recirculating liquid” to achieve increased pressure while fluid is propelled through the pump with a centrifuge.
A set of mechanical diaphragms navigate back and forth to elevate and reduce the pressure. A valve prevents the liquid from creating a “back flow”—these boast a high degree of accuracy, with the industrial community using these extensively.
These refrigerated components, also called “capture or trapping” pumps, function by cooling a contained space where the air molecules are condensed with the resultant liquid removed.
Some of the entrapment pumps are referred to as “ion” pumps since these incorporate electrical fields to create condensation instead of cooling the space. The suggestion is that the ion pump performs for gas storage, which will be released at some point.
What is the Functionality of a Vacuum Pump?
A vacuum pump is exceptionally powerful and has the potential to be hazardous. Some possible risks with use:
- Noxious fumes when ventilation is insufficient
- Fire with potential overheating or potential malfunctioning
- Faulty wiring can lead to electrical shock
- Moving parts expose individuals to the possibility of injury when mishandled
- Spilling contaminated pump oil with incorrect use
A priority with any equipment is safety. The primary factors for optimum safety and health include always ensuring you’re familiar with the components before attempting use. Also:
- Pay attention to the oil and change it as needed
- Handle oil disposal properly
- Pump outlet and exhausts should be free of obstructions and blockages
- Ventilations should be adequate in any area where pumps are in use
- Use belt guards properly
- In case there are faults, ensure there is a spill tray for leakages
- Tubing should be adequate for operation and compatible with the pump. These should be changed out when needed
- Hazardous or combustible materials should be stored properly
- Flaws in cables and switches should be reported immediately
Manufacturer instructions should be made available for the operation of vacuum pumps for the specific model you’ll be using.
Before attempting usage, each person should have an understanding of the pump’s basic working principle and the properties of the components. Go here for a guide on pump care and upkeep.
As with any mechanical device, there is a potential for equipment to fail or begin to slowly lose its ability to operate at peak performance.
You should be aware of the warning signs or red flags that the component is suddenly failing in its functionality. Perhaps it won’t switch on at some point when you attempt to use it.
More than likely, however, it will be a gradual build-up of symptoms as the internal system starts to wear down. Some issues you’ll notice include:
- Unusually loud
- Oil leaks
- Pressure dropping
When a component is in disrepair or malfunctioning, it must be inspected and replaced as soon as you notice a problem to avoid repercussions from the poor performance.
