The Volumetric Blower is an "oil-free" lobe pump for air or non aggressive/non explosive gases suitable to operate with a maximum backpressure of 1000 mbar at discharge, and a maximum vacuum of -500 mbar, withing the allowable temperature limits.
The Air Cooled (AC) Exhauster is an "oil free" rotary lobe pump for air or non aggressive/non explosive gases suitable to operate with a maximum vacuum of -0,85 mbar, within the allowable temperature limits.
- The three-lobe rotor is the evolution of the classic bi-lobe design, shaped like an "eight". This design ensures higher bending stiffness, and lower pulsation amplitude that consequently reduces vibration. The economic advantage in the bearing life is appreciable. The compressor noise is remarkably decreased as well.
- The synchro-gears are case hardened and tempered. Gears are accurately ground to ensure optimal timing. The "long addendum" involute design gives maximum efficiency with virtually silent mechanical operation.
- Pump's body, sump and covers are assembled with flat gasket to ensure maximum tightness. This results in increased reliability which decreases mainenance costs.
- The sealing of the rotors is achieved with labyrinth seals, which do not make contact and therefore do not create friction. This is ideal for the rotor's high rotation speed. This solution saves money due to the decrease in energy dissipation and absence of any other expensive cooling system.
