The volumetric lobe vacuum pumps “B” series are machines that, thanks to the conjugated rotation without contact of two rotors (with two lobes) within a suitably shaped chamber, create volumes and transfer air through the inlet manifold to the outlet one. They operate completely dry without any lubrication or residues generated by brushing or contact during rotation.
The BCA pumps can be supplied with motors in accordance with IEC 72 B5, with three various configurations:
- BCA pump without motor
- BCA pump with IE3 motor
- BCA pump with IE3 motor + AdaptShield
The AdaptShield system integrates the pump BCA function with highest efficiency standards through an algorithm that controls the pressure range monitored by two sensors, both placed on the pump’s inlet and outlet. The system is integrated within the inverter, and it continuously sends data in order to manage the electric motor speed variation. This procedure allows the system to fully use the volumetric capacity of BCA pump. Moreover, the AdaptShield system protects the BCA pump from possible malfunctions.
In the vacuum sector, the volumetric lobe vacuum pumps should always be inserted in series with other pumps, normally of a lower flow, known as primary pumps (“L” series lubricated pumps). This way the unit (“CBL” pumping systems) is capable of:
- achieving extremely low-end pressure levels (normally 10 times lower than what can be achieved with just the primary pump);
- accelerating the emptying times of a closed volume.
