For Pneumofore UV vacuum pumps the moulding process of glass containers is the core business: in this tough round-the-clock heavy-duty application,
Pneumofore managed to collect experiences over more than 50 years. Our position of worldwide leader of vacuum pump systems for IS machines was confirmed by many glass companies visiting our booth, especially coming from middle and far east where glass bottles and containers production is growing up. Pneumofore presented a vacuum system in operation, composed by the air cooled UV16 VS30, 1.165 m3/h variable speed rotary vane vacuum pump and the DVF125 demister filter.
All visitors showed particular interest in the variable speed drive installed on UV16: its quickness and precision in managing any variation of vacuum requirement impressed both technicians and managers. Based on the feedback information received from a vacuum sensor and the vacuum level set in the control panel of UV16 (150 mbar abs typical in the hollow glass industry) the VS drive is able to keep the vacuum constant in the process by changing the motor speed.
