Gardner Denver Nash Germany supplied the complete vacuum system for dewatering in the forming and press sections of the new PM7 paper machine in Dunaujvaros. This technology has already proven itself in every other paper machine within the Hamburger Group, with robustness, efficiency and flexibility that guarantee the highest operational reliability.<\/p>\n
On the new PM7 in Dunaujvaros, nine NASH 2BE3 vacuum pumps are used. Each pump is driven by a motor equipped with a frequency converter, allowing the rotational speed to be set to exactly suit the actual process conditions. This causes the vacuum pressure to adapt to process conditions as well. Additionally, three centrifugal fans for the low-vacuum scavenge points in the forming section have been included. As a result, the vacuum system provides the greatest flexibility at optimum efficiency. <\/p>\n
For the plant operator, the advantages of a NASH liquid ring vacuum system were obvious:
\n•\tAn extremely robust system: overload safe and resistant to process failures
\n•\tVery high overall efficiency, particularly in conjunction with optimum control
\n•\tOptimum felt dewatering through the volumetric operating principle of the liquid ring vacuum pump – the scavenge pressure adjusts automatically to suit the felt permeability
\n•\tScavenge-side liquid carry-over with low fiber content is not a problem for the NASH pumps
\n•\tRotation speed control offers the potential of high energy savings
\n•\tLow specific power requirements
\n•\tLow noise emissions due to low peripheral speeds of the vacuum pump
\n•\tFuture system adaptation, without influencing other scavenge points, is easily done by changing the rotation speed of individual vacuum pumps
\n•\tHigh operational safety, even if individual vacuum pumps are deactivated
\n•\tVery low service and maintenance costs
\n•\tConfidence in more than 100 years of know-how accumulated by the market leader in the paper industry<\/p>\n
With the decision to use NASH vacuum pumps, the plant operator also made a decision for an innovative, environmentally friendly and economical attractive solution.<\/p>\n","protected":false},"excerpt":{"rendered":"
