Advanced and efficient vacuum supply in paper bag production

GSD-Verpackungen - Gerhard Schürholz GmbH is specialized in the production of paper bags and paper shopping bags. The majority of the processing machines requires vacuum to hold, transport and finish the individual bags. GSD-Verpackungen has made energy savings of over 50% and reaped many other benefits for its advanced production systems by changing over from vacuum supply generated by individual vacuum pumps to the respective machines, to a centralized vacuum system from Busch.

(businesspress24) - GSD-Verpackungen was founded in Drolshagen in 1877 and has been owned by the Sch
Complex special processing is also available in addition to standard sizes and designs. Elaborate print designs with up to eight colours can be created using a flexographic printing process.

The company currently employs a total of 160 staff. Production runs five days a week, and gs are stacked up ready to go at the end of the inline systems, and can be packaged immediately.

Many of the machines for the paper bag production need vacuum for various processing or handling tasks. Vacuum is used to either hold or move paper, depending on the machine. In the past, a total of 22 rotary vane vacuum pumps of different sizes were in operation to generate vacuum. This was a thorn in the side of Production Manager Jon, but were equipped with self-lubricating carbon vanes. Their abrasion released a fine carbon dust into the air, which was deposited around the vacuum pump. Moreover, they need to be replaced regularly, which was associated with high costs. Spare vacuum pumps always had to be ready for use in ordeps.

Dr.-Ing. K. Busch GmbH then created a completely new concept for generating the vacuum for all production machines on all five inline systems. Production Manager Jnline system to be connected. The centralized vacuum system is connected to all machines by means of one line, and guarantees the vacuum level can be maintained at 300 milibars throughout operation.
The benefits were clear even in the first few months after the centralized vacuum system was installed: no noise emissions or indoor air pollution from carbon dust around the workstations in the production areas.

There were also vast energy savings compared to the former decentralized vacuum supply. The Mink claw vacuum pumps are each driven by energy-efficient IE3 motors with 6 kilowatts of rated power, corresponding to energy consumption of 30 kilowatts for the five motors in total. In practice, the first few months of operation showed that demand-driven control of the new centralized vacuum system from Busch meant that only two or three Mink claw vacuum pumps at most need to be operational simultaneously. The actual power consumption is then 60,000 kilowatt hours a year, with a theoretical setup of 2.5 vacuum pumps and an operating time of 4,000 hours. The motor ratings of the rotary vane vacuum pumps used previously were 32.5 kilowatts in total, corresponding to an annual power consumption of 130,000 kilowatt hours. The result of changing from decentralized to centralized vacuum supply is a saving of 70,000 kilowatt hours, or 54% of the energy costs.



Mink claw vacuum pumps operate entirely contact-free, meaning that none of the internal moving parts in the vacuum pump come in contact with each other. As a result, there is no wear, making this type of vacuum pump nearly maintenance-free. Busch recommends a preventive annual change of the gear oil when using the systems in 24-hour operation. This can be performed while the system is in operation, by switching off the relevant vacuum pump in the centralized vacuum system. Vacuum generation for production is still ensured by the four other vacuum pumps thanks to the cascade connection and the operation of one of the five Mink claw vacuum pumps with a frequency-controlled motor. For Jnd total vacuum pump failure are a thing of the past.

Busch Vacuum Pumps and Systems was founded by Dr.-Ing. Karl Busch and his wife Ayhan Busch in 1963. Dr.-Ing. Karl Busch developed the “Huckepack”, which was the first vacuum pump that could be used for vacuum packaging of foodstuffs. The follow-up product, the compact “R 5” rotary vane vacuum pump, revolutionized food packaging. A further milestone represented the development of the “COBRA” screw vacuum pump. In 1971 the international expansion of the Busch group started with the founding of a sales company in the UK. The first production plant outside Germany was established in the USA in 1979.
