The Ultimate Guide to Buying the Right Dry Vane Pump

Dry vane pumps are kinds of positive displacement pumps; they have vanes which are placed and joined to a rotor which is placed inside of a cavity that is constantly rotating. Vane pumps can effectively manage the liquids of low viscosity; some of them being alcohol, gasoline, ammonia, and so on. These pumps are especially easy to maintain as compared to the other kinds of pumps, and they can deliver excellent performance even when they work.

The dry vane pump can at a go attain approximately 70mbar of pressure at the most and can at least attain a minimum pressure of 0.5mbar. No pressure lower than 0.5mbar can be attained by the dry vane pump. This is because the inlet valve which is designed for the safety of the vacuum, remain open and cannot be closed whenever the diaphragm is pulled downwards, thus disabling the dry vane pump in achieving pressures lower than that mentioned above. Dry vane pumps can be used for a wide range of issues, like Aerosol and Propellants, refrigeration, for filling up the LPG cylinders, for the purpose of transferring fuel in the services related to Aviation matters, distillation industry, solvents, and much more.

These pumps are accepted widely because of the suction characteristics which are really good, and also known and used widely for their feature of dry priming. However, they cannot work efficiently in high pressures or for applications of high viscosity. Dry vane pump is more useful and cost-effective for the industrial purposes and must thus be chosen for long-term projects.

Dry vane pump can work efficiently in temperatures ranging from -32 degree Celsius to 260degrees Celsius. This means that these pumps are efficient in working with a huge range of temperatures, and thus they are effective in delivering quality performance too.

Tips to Keep in Mind While Buying A Dry Vane Pump:

One is always troubled by the question of how to choose the perfect dry vane pump for the right purpose. Discussed below are a few very important things to keep in mind while one venture to buy dry vane pump for various industrial uses:

  • The very first question which should be answered by one is about the purpose of the dry vane pump. Is it fit for the purpose which one has? Dry vane pump can be used for the thinner and lower viscous liquids.
  • Is the cost of the dry vane pumps lower than oil lubricated pump? It is always the case that the cost of a dry vane pump is much lower than the oil lubricated ones. Earlier it was the case that the dry vane pumps were much costlier than the oil-sealed ones. Thus, one should not ever be paying more for these than the other kind of pumps.
  • One has to remember that one cannot just buy a dry vane pump and forget to think about its yearly maintenance, which is a vital factor.
  • Energy efficient vane pumps are to be chosen always by a consumer. If such machines are not bought, then there are high chances that the machine will never contribute to saving energy, nor will it have a good longevity. How does one know if these pumps are energy efficient? Every such machine has a facility of putting it on “standby “mode, as instructed by the manufacturer on its manual guide.

Although the dry vane pumps are really easy to handle and have a lot of advantages over oil lubricated pumps, they do have a number of complex inner parts, and they must not ever be used with abrasives.
