The Adixen Alcatel RSV601 RSV 601 Roots Pumps are suited to a wide range of vacuum applications. In combination with primary vane pumps, or dry pumps, they achieve low pressures with high pumping speeds. Adixen Alcatel quality and reliability without any mechanical contact. They are proven in industrial and chemical applications, the Adixen Roots pumps achieve high reliability. The canned motor concept allows the motor armature and drive shaft to be enclosed in a vacuum tight “can“, this design eliminates external shaft seals and potential leaks, resistant to process gases and condensables. The careful choice of quality components makes Adixen Alcatel Roots well adapted to aggressive environments. Aggressive environments require vertical flow Roots, to prevent condensate from accumulating inside the pumping chamber. Simplified maintenance and on site repair and maintenance capability. Low noise Compact design, quiet operation, low vibration level and air cooled. The RSV Series is helium leak tested to < 1.10-7 mbar l/s and is ideally suited for hazardous duty.

The lubrication requirements of these RSV 601 booster pumps are limited to the ball bearings and synchronization gear train. The two casings containing the oil are isolated from the pumping chamber by a sealing system (lip seal for dry friction in PTFE + treated friction ring + deflectors) which prevents any possibility of oil contamination of the pumped gases. Roots vacuum boosters operate in conjunction with a roughing pump (RP) which enables the gas flow to be delivered against atmospheric pressure. Consequently, the pumping speed/pressure relation is directly related to the performance characteristics of the associated roughing pump. The power consumption of the Roots machine is according to the pumping speed, the rotation speed and the pressure difference between inlet and outlet sides.

The most noteworthy feature of these RSV 601 boosters is the motor coupling which is made only with static parts. The roots RSV units are called ”in vacuum rotor” machines, i.e., the rotor of the electric motor is completely isolated by a stainless steel cylindrical sleeve. This sleeve is centered inside the motor stater and attached to the machine casing, with a static o-ring providing the necessary seal. In this way, any possibility of leaks around the motor/pump coupling is precluded by eliminating the shaft passage with dynamic seal used in conventional set-ups. The oil casings are sealed from the pumping chamber by means of a link tube connecting the casings to the outlet of the machine. This avoids the creation of any pressure difference between the pumping chamber and the casing which would otherwise be conducive to oil migration. An oil mist filter avoids any oil back-streaming into casing tubes. (For Users Manual download .pdf below at AVAILABLE DOWNLOADS.)
