HyVac Products, Inc. primary focus is categorized as high, medium and low vacuum pumps. Our product offering in vacuum pumps is really quite broad and is somewhat difficult to quickly break down so here goes. We make old style belt drive pumps that have been in use for years. We also make direct drive pumps that are newer generation vacuum pumps. The direct drive style is faster for the size and physically smaller than the older style belt drive pumps.  Both styles create vacuum using the same rotary vane principle which hasn't changed much for a very long time.

Many of these pumps are used to achieve vacuum pressures in excess of 29.5" of mercury vacuum. They are often referred to as oil sealed rotary vane pumps. They use special oil to lubricate and create the vacuum pressures that the pumps specify out at.

Low vacuum pumps are generally from atmospheric pressure to about 15" mercury vacuum.  We also have some pumps that are rated lower in this category.  They have varying principles of operation and varying performance criteria to achieve the vacuum desired.  Some use oil, some do not.  Some use water to create a vacuum seal.  The good part is that depending on the application there are a wide variety of solutions for your needs, some better than others, for the application.  That is why when you call us we generally ask the big question, "What is the application?"  We are not being nosy we just may have a better cost effective alternative than what you were thinking about.

Medium vacuum pumps are generally from atmospheric pressure to about 25-28" mercury vacuum.  We also have some pumps that are rated lower in this category.  They have varying principles of operation and varying performance criteria to achieve the vacuum desired.  Some use oil, some do not.  Some have no moving parts.  

High vacuum pumps are rated from atmospheric pressure to about .0001mm of mercury vacuum.  We also have some pumps that are rated a little lower in this category.  They have varying principles of operation and varying performance criteria to achieve the vacuum desired.  Most of the pumps in this category use oil as the vacuum creating mechanism.  

"Very High" vacuum pumps are really a combination of pumps to create vacuum in excess of 10-4 Torr (.0001mm Hg).  These pumps get very, very technical.  They also get pretty expensive.  The applications, fittings and the associated trouble shooting get a little time consuming to get involved in. There are very many issues that get intermingled including process materials, chamber design, vacuum source design just to name a couple.  At this time, we are included from a rough vacuum pump standpoint which is often required to create a base pressure from which the more technical pumps start to do their work.  Included in this category are diffusion and turbo molecular pumps to name a few.  If you have these needs here, we may have part or all of the equation and often do, but assuredly have the people that can assist you.
