Oil-free rotary vane vacuum pumps consist of a rotor in an eccentric position rotating inside a cylindrical body.

This rotor is equipped with grooves in which the vanes are inserted. Because of the centrifugal force, during the rotation the vanes are pushed into contact with the body, creating close spaces that increase their volume drawing air from the container to be emptied and expelling it from the “outlet duct”. Oil-free rotary vane pumps can run continuously both at atmospheric pressure and at the highest vacuum. However, they cannot be used when the aspirated air contains moisture, oil or other traces of liquid.

Claw Pumps create air volume and transfer it through the intake duct to the outlet duct by means of the rotation of two claw shaped rotors in a moulded chamber.

The dry running contactless rotation of the rotors is synchronized by gears without any lubricant present, thus avoiding any residue generated by friction or rubbing during rotation. The gear wheels themselves are lubricated with oil and are enclosed in two compartments separated from the rotation chamber by gaskets. Claw Pumps guarantee low operating costs thanks to moderate energy consumption and high efficiency. Maintenance is minimized and the level of performance is maintained for longer by virtue of the lack of friction between the moving rotors.

Piston pumps may be used in presence of moisture and have no restrictions on use.

Versions are also available with safety guard and intake filter for use as mobile units. The operating principle of piston pumps is based on a piston that alternatively moves in a cylinder. The cylinder is equipped with valves that inhale air and exhale it outside. If used as compressors, these pumps create a pulsating flow that requires the presence of a reservoir.

Lobe pumps are equipped with two lobe rotors having a singular geometrical shape that emphasizes the positive aspects of this design and annulling the negative ones, as gas recirculation.

Moreover, the shaft sealing is ensured by a dynamic gasket preventing any leakage. These lobe pumps should always be used together with a primary lubricated rotary vane vacuum pump increasing the total flow rate at low operating pressures and reaching a great improvement of the final pressure.

The operating principle of the DVP side channel blowers is simple: a small wings equipped rotor rotates inside a stator.

Small vortexes of air created by the centrifugal force and the rotation are dragged by the vanes from the aspiration toward the drain. There are no parts in contact, thus the side channel blowers do not require routine maintenance but, since the intake air is also used as cooling fluid, they can operate continuously only within certain ranges of pressure. To prevent a damage of the engine it is indeed necessary to install vacuum and pressure limiting valves. All versions can be used as compressors. If used as a compressor, the output flow is clean and free of pulsations.

The lubricated rotary vane vacuum pumps are used when the intake flow may contain moisture, or when a better final pressure is required.

These pumps may run continuously within certain pressure ranges, or connected to containers to be emptied, whose volume is appropriately sized for the pump flow rate. Long-term use at atmospheric pressure is not recommended. The lubrification allows this pumps to intake water vapour. To avoid a condensation of the water vapour, the lubricated rotary vane vacuum pumps are equipped with the gas ballast, a system that introduces air in the compression stage and changes the vapour saturation pressure thus avoiding the condensation. Into the WR pump version the gas ballast system is improved and reinforced.

High vacuum pumps are used when the final absolute pressure required is very low.

These pumps may run continuously connected to closed containers to be emptied, and may not run continuously at length, at atmospheric pressure. The exhaust from these pumps is not filtered, thus, special purifiers are available for fumes. The operating principle of the high vacuum pumps is like the lubricated rotary vane vacuum pumps one. However, in this case, the stator is immersed in the lubrification oil which has also the function of sealing the air loss. The pressure levels reached by this type of pumps are higher than any other rotary vane pump. These pumps are equipped with a gas ballast system to avoid the condensation of the water vapour. The high vacuum pumps can be made of a single rotor-stator group (single stage) or they can be made of two rotor-stator groups connected in series, so the first group drain is connected to the second group intake system (double stage).

The industrial vacuum systems are designed and manufactured to be used in all the same applications as the individual pumps, and mainly in centralized vacuum systems, as units suitable for creating and maintaining a certain vacuum within the system that allows proper operation of the equipment connected to it.

The installation of an industrial vacuum system is advantageous especially in terms of energy savings, because the pumps automatically switch on only when needed by the user.
