Industrial vacuum pumps are used in many industries, and are central to how processes work. The dental industry, for example, relies heavily on vacuum pumps to do their job efficiently. There are two main different kinds of vacuum pumps, wet and dry, that a company can choose from for their business. The wet vacuum pumps are seen as more traditional vacuum pumps, and have been around a lot longer than the dry vacuum pumps. Many companies, including companies in the dental industry, have been switching over to dry vacuum pumps and there are a few main reasons as to why they are doing so.
The traditional wet vacuum pumps are loud and smelly from the burnt oil and the debris that gets trapped inside the tanks for extended periods of time. They also use extreme amounts of water, some up to 200,000 gallons a year. This presents a problem not only financially but also poses a problem when thinking of the environment and the water levels around the world.
The cost of running a system that uses large amounts of water is large. Since the amount of water a wet vacuum pump system uses per month is equal to an Olympic size swimming pool, many people would just see dollar signs when looking at the machine. Some cities have also regulated water usage, and water waste, which could pose a problem financially as well as efficiency wise for manufacturers who currently use the wet vacuum pump.
Wet vacuum pumps that use oil also exhaust oil vapors into the air which can lead to a polluted environment, and requires regular maintenance to make sure the oil is at the proper level, similar to a car. There is also a concern of backup from debris that is removed in the water exiting the wet vacuum pump. Often times, there is a regulation that requires the instillation of a backflow preventer, which can be costly for the company.
If you look close enough you can always find the negatives of anything, so it is no surprise that the list is long for wet vacuum pumps. They still serve their purpose in manufacturing and various other industries however, and have not been completely replaced by dry vacuum pumps. After all, no one ever said too many options were bad.
