Description

With its DuoLine rotary vane pumps, Pfeiffer Vacuum has offered two very successful ranges for many years now. Their long life and pumping speed, irrespective of the gas used, are the outstanding properties of these pumps. Pumps belonging to the DuoLine series cover a pumping speed range of 1.3 to 300 m3/h. In the 5 - 21 m3/h range. Pfeiffer rotary vane vacuum pumps address the requirements of all major vacuum applications in diverse industries. Available in five different series, these pumps are dedicated to high vacuum applications, where reliable pumping and low vibration are important.

How Rotary Vane Vacuum Pumps Work

A Rotary Vane Vacuum Pump is a positive-displacement pump that consists of both housing and vanes. Those vanes are strategically mounted onto a rotor, which then rotates inside of a circular casing. The center of the circular casings are offset which causes eccentricity. This is the distance between the centers of two cylindrical objects one of which surrounds the other. Vanes slide into and out of the rotor and seal on all edges. This creates vane chambers that do the pumping work. As the rotor turns, gas flows into the enlarging suctions chamber until it is sealed off by the second vane. The enclosed gas is compressed until the outlet valve opens against the atmospheric pressure.

Many industries use rotary vane vacuum pumps, including the automotive field. They use the rotary pumps for testing and manufacturing, braking, power steering, automatic transmission and supercharging systems. Aircraft is another industry that uses rotary vane vacuum pumps. Other uses for this type of vacuum pump include air conditioning and refrigeration industries, microelectronic manufacturing, medical and dental labs, physics departments and more. Because it’s a vacuum pump, it also has many useful uses in industrial and laboratory settings.

The Advantages of Rotary Vane Vacuum Pumps

There are many different advantages when it comes to using a vane pump. Vane pumps are self-priming, robust and supply constant delivery at a given speed. They give uniform discharge with minor pulsations. Another advantage is that the vanes can be replaced easily. There are many repair kits offered or you can easily get a professional to repair it for you. They are cost-effective and are fairly inexpensive. A really good heavy-duty vacuum pump can be purchased for around $2,000. And if you need to go cheap, you can purchase one of those low quality, low duty vacuum pumps for as little as $80. Vane pumps have good airflow and can handle gas loads containing vapors and gasses and their volumetric and overall efficiencies are high. Another great benefit is the vane pumps can run dry for short periods of time. Lastly, rotary vane vacuum pumps develop a good vacuum!
