Selecting Precise Vacuum Pump For Your Industrial Needs

Business

You have a wide range of options when selecting a vacuum pump. You need to consider the specific type of application for which it is required before opting for any particular one. The different vacuum pumps offer different vacuum levels for the various capacities of displacement. The four main types of vacuum pumps, which are often used, are listed below.

  1. Diaphragm:

The diaphragm vacuum pumps are considered as ‘dry’ pumps, which make use of the pulsating motion, which opens and closes the valves for moving the air. The valves are normally made of polytetrafluoroethylene, which makes the pump resistant to not only corrosives but also damages from the vapors. These are specifically designed to eliminate the use of oil.

The maintenance and the operation of these pumps tend to be a cost-effective affair, though you might have to spend a little more when you decide to opt for this. These pumps handle liquids, which are highly viscous and can be used in different types of samples. However, these pumps have limited applications. As compared to the other vacuum pumps, the diaphragm pumps have lesser vacuum levels and low capabilities of displacement. The advantage of these pumps is that you can use acids and solvents without these getting corroded or damaged in any way.

  1. Rotary Vane:

With the low up-front cost, the rotary vane pumps are a favored choice of many due to various advantages. These pumps make use of oil to ensure lubrication and a tight seal and to cool the rotors by removing heat. There are chances of the solvents getting condensed in the oil and damaging the pump’s insides. Thus, it is important to collect the evaporated vapors from the pump. For the protection of the pump and for the collection of vapors, you need to use the Cold Traps or Condensers. These pumps work out to be a little on the costlier side, as you are required to change the oil after every 3,000 hours of usage.

These rotary vane pumps work apt for the applications of freeze drying.

Besides this, you have the Hybrid pumps, which have both the rotary vane and the diaphragm in the pump, or the Scroll pumps are dry pumps. Whichever pump might be your requirement you need to know, the maintenance is important and top priority to make the most out of these pumps.

Maintenance of Vacuum Pumps:

  • Maintaining the vacuum pump is important, as this can lead to the undisrupted running of these pumps and favors a longer lifespan. Many manufacturers offer service kits for different types of vacuum pumps, which have the replacement parts and the required tools. You can think of opting for a backup pump in case of emergencies. This can save on any downtime and keep the work going without any interruption.
  • Regular maintenance includes a regular oil change, control of the temperature, and making sure there is no oil overheating. You need to make sure that the placement of the pump is in a well-ventilated area, as doing this will take care of the temperature factor. You need to be aware of the fact that oil tends to get more viscous with excessive heat. This can lead to the failure of the pump. Besides this, there are chances of the rubber getting brittle with too much heat.
  • You need to ensure that only gases, which are filtered enter the pump, as normally the pump pulls in anything. There is no discrimination. Water entering a pump can lead to excessive damage and there might be a requirement for the replacement of the pump. Make sure this is repaired on an immediate basis.

Taking a little effort in the maintenance of the vacuum pumps can save you from unnecessary expenditure and labor.
