Oil recirculating type rotary vane vacuum pumps
with nominal capacity 70 m3/h.

abs. In the BVM version the ultimate vacuum is of 10 mbar
abs. The two versions differ only in the oil recovery system
from the oil separation chamber.
The pumps are designed for continuous operation within the
ultimate vacuum and 400 mbar abs.
The standard construction includes:
flange mounted electric motor;
flexible coupling between
motor-shaft and pump-shaft;
bearings on both sides of the
centrifugal-type fan directly
fitted onto the pump shaft
extension for the cooling with
inlet mesh filter to prevent solid
