Roots Vacuum Pumps

Roots vacuum pumps ruvac which are also called roots blowers are rotary plunger type pumps where two symmetrically shaped impellors rotate in opposite directions inside the pump housing.

Roots vacuum pumps. The high pumping rate for hydrocarbons allows the roots pump to provide an effective isolation between oiled pumps such as rotary compression pumps and the vacuum chamber. These pumps are therefore ideally suited for applications in low or medium vacuum and are frequently used in. A variant uses claw shaped rotors for higher compression. Multistage roots pumps are dry vacuum pumps used in low medium high and ultra high vacuum systems to produce dry conditions.

The simple single stage roots pump is most commonly employed as a booster pump for several types of fore pumps such as rotary vane pumps screw and liquid ring pumps to improve ultimate pressure and pumping speeds. 4 7 1 design operating principle. Roots vacuum pumps for many years now roots vacuum pumps have been well established in the area of vacuum technology. In combination with backing pumps which compress against the atmosphere these pumps offer lots of advantages.

In combination with backing pumps which compress against the atmosphere these pumps offer lots of advantages. Its working principle is similar to roots blower which use two figure 8 rotor synchronous rotation in the pump shell so as to complete the suction and exhaust process. Roots pumping stations are used in low and medium vacuum applications and are a reliable solution offering high pumping speeds in the transition range from atmospheric pressure to 10 3 hpa. The frictionless pumping action of the lobes means that dry operation is assured.

In combination with backing pumps which compress against the atmosphere these pumps are capable. The roots type blower may achieve an efficiency of approximately 70 while achieving a maximum pressure ratio of two. The gear box and bearings of roots pumps are separated from the gas pumping chamber. Roots pumps are used where great volumes have to be pumped.

Pfeiffer vacuum has a large variety of roots pumping stations with different backing pumps gradations and accessories. Roots vacuum pumps for many years now roots vacuum pumps have been well established in the area of vacuum technology.
