- This HyVac Products, Inc. file is in MS Excel 2000 Format and allows the user to determine
pump requirements for mechanical high vacuum pumps using accepted standard vacuum
calculations. The user inputs pressures, volume to be evacuated and time to
evacuate. The resultant numbers can then be compared with vacuum pump offerings from
HyVacs' line of high vacuum pumps. The numbers can be compared effectively for other
similar high vacuum pumps but are predicated on using an oil sealed rotary vane pump. This
is a standard pump for many applications and makes assumptions from these given
"pump" efficiencies. It is not perfect but gives the user a benchmark from
which to start sizing a pump for an application. Assumes a perfectly vacuum tight
and a non-outgassing system in other words "perfect world" which
few of us live in.
Convert-It.exe - A nice little windows based unit conversion program for
establishing conversions among a number of differing measured units. I like it
because it also features pressure values, along with standard volume conversions.
If you call, we can size
pumps pretty quick.
