Products:   Liquid ring vacuum pump - the Wittig® Aqualine Series for suction vehicles comprises seven types designed for flow rates up to 3.100 m³/h. The on-piece cast housing with integrated suction-compression connecting ducts requires very little fitting space. A further advantage is the unit’s double-end drive shaft, which permits either clockwise or counter-clockwise drive rotation. Their low weight is attributable to the use of aluminium and the state-of-the-art integrated design principle. Liquid ring compressor vacuum pumps can be driven by the vehicle engine via auxiliary drive. Alternatively, a hydraulic motor may be flanged directly to the unit.     Keywords     www.vacuum-guide.com
