Operating Principle V-Series

Pressure increase by volume reduction is the principle behind rotary vane operation. In a cylindrical housing a rotor is positioned eccentrically so that it is on the top almost touching the cylinder. Rotor blades or vanes as they are called, are positioned inside rotor slots.

 

When the rotor starts turning, due to centrifugal force the blades are thrown out and slide against the internal surface of the cylinder. In this way a cell is formed between two blades with a volume that changes constantly during rotation. Air enters from the inlet port into a cell until the rear blade reaches the far end of the inlet port. At this point the cell has achieved its maximum air volume. As the cell then moves away from the port its volume becomes smaller and smaller, the air is thus compressed and the pressure rises. This continues until the pressure in the cell exceeds that in the pressure chamber and the compressed air then exits through the outlet port.

 

Some models are fitted with exhaust valves which stop the backflow of this discharged air if the maximum pressure has been reached. In a vacuum pump the process is similar, but the cell gives decreasing pressure, and the chamber is at atmospheric pressure. With pressure-vacuum pumps the lower end of the inlet port(s) for the vacuum is moved forward. The cell can now be filled through second inlet. To avoid impairing the vacuum, this second inlet port is located about one cell segment away from the main suction port. The ratio between vacuum and pressure capacities can be influenced by the choice of inlet port.

Elmo Rietschle Oil Lubricated V-Series Vacuum Pumps are generally regarded as the most powerful of all production vacuum pumps.  In virtually every case, if you compare the performance of an Elmo Rietschle VC Series vacuum pump with a similar, or same size motor driven pump from any other manufacturer, you will find that at operating pressure, (ie.1 Torr) the Elmo Rietschle vacuum pump will out-perform its rival by a huge volume.  That means that your Elmo Rietschle Vacuum Pump will package more items, evacuate more molds, lift more product than any other pump with the same size motor.

 

Elmo Rietschle Oil Lubricated V-Series Vacuum Pumps do not contain plastic or phenolic laminated vanes, because the evidence of many years shows that these types of vanes swell and stick in their slots and do not form a tight seal on the wall of the vacuum cylinder.  Instead, you will find that our V-Series pumps are all equipped with Cast Aluminum Vanes.  Our vanes form a tight seal and will not stick or swell.  We are so confident that we back all our Oil-Lubricated Vacuum Pumps with a 5 Year Vane Life Warranty.  Of course, the biggest gain from all this superior technology, is you.  Lower maintenance costs, longer pump life expectancy and superior pumping volume.

 

The next time that you consider purchasing a Oil Lubricated Vacuum Pump, take a good look at the ‘Performance Curve’.  Decide the ‘Volume’ and the ‘Pressure’ that you would like to operate at.  Plot the place on the Elmo Rietschle Performance Curve.  Now plot the same place on the curve of any other pump manufacturer.  Now how is that for performance?  Need some help with this.  Sometimes companies try to confuse you by using European or Eastern measurements.  In North America, we tend to most frequently use Inches of Mercury, (Hg”) or Torr for vacuum depth and Cubic Feet per Minute, (cfm) for volume.  We can assist you transpose the alternative values into measurements that will help you to compare.
