Dry Vane Vacuum Pump

by - September 17, 2019

You would have often heard about vacuum pumps, apart from their household usage, they also find use in industrial cleaning. There is a different mechanism via which these pumps operate, and, in this blog, we will be focusing on the dry vane vacuum pump. A vacuum pump is an industrial device that is used to remove the gas molecules from inside a sealed container which will leave behind a vacuum. It has several industrial uses such as in the electronic manufacturing industry where it is used to produce CRT tubes, electric bulbs, and lamps, semiconductor materials, and glass coating, etc. it is also used for the purpose of scientific research in the areas of pharmaceutical processes, surgical instruments and several other research and development instruments which require the use of a vacuum pump either by itself or along with the use of other complementary machines.

Why Dry Vane Vacuum Pumps:

These pumps work in line with the rotary vane technology in pumps. Unlike the conventional vacuum pumps, you would find that the dry vane vacuum pumps don’t require lubrication. One of the reasons that the dry vane vacuum pumps are preferred over the conventional vacuum pumps is because the oil can lead to several problems. Rigorous usage of the machine may cause the oil to heat up which may catch fumes and may be hazardous, besides there is a need for regular lubrication or oil change. However, when it comes to dry vane vacuum pumps, then the absence of nullifies all these impacts.  The dry vane vacuum pumps have self-lubricated rotary vanes which require no fluid to keep them running. They are considered to be environmentally friendly because of the prevention of the use of oil and also extremely reliable and efficient. Since there is no oil many of the factors, which lead to the ultimate break down of the machine, can be avoided.
The dry vane vacuum pumps have graphite vanes in the compression chambers and materials which are specially chosen for the device and it can, therefore, provide a high vacuum level even after continuous usage. A powerful cooling fan is generally installed to prevent the overheating of the device and provides it with a continuous flow of cool air hence reducing the need for rest periods for the machine.

Summing Up The Advantages Of The Dry Vane Vacuum Pump:

  • Oil Less Operation: It does not require the use of oil or any other lubricant
  • Quiet And Cool Operation: The use of graphite vanes and cooling fans makes the device very reliable
  • Minimum Maintenance: The rotary vanes have a large shelf life and since there is no lubricating liquid attention of the workers on changing the oil is not required
  • Continuous Duty: There is no problem of overheating or changing the oil before the harmful gases start to be produced. This allows the machine to be used continuously for as long as required.
The pump does provide a list of advantages but the amount of vacuum pressure to be created or the amount of liquid that is to be sucked out also has to be taken into careful consideration. This type of pump can only work up to a certain level and after that other types should be considered.
This type of vacuum pump is an excellent choice for a medium to a varied range of investment and the long run cost is further reduced as there is no cost of lubricant involved and maintenance costs will also be reasonably low. The dry vane vacuum pump operates silently and is also more durable as compared to the conventional pumps, thus making them last longer.
