Elmo Rietschle introduces dry screw vacuum pump for food packaging - and puts an end to staggering life cycle costs you're used to with oil lubricated rotary vane pumps!

Have you ever calculated how much you pay per year on service costs for your oil-lubricated rotary vane vacuum pump, the kind of pump that currently dominates the market in the food processing industry? In a typical protective-gas application, average maintenance costs of € 2,000 are incurred at least every 2,500 operating hours. The reason: up to 8 liters of special oil are required per maintenance. Including the admittedly moderate purchase price of such units, this results in life cycle cost of about € 30,000 over a 4-year period. Not exactly small change. But totally avoidable!

Although its purchase price is somewhat higher, the Elmo Rietschle VSI screw vacuum pump has a payback of less than 12 months in oxygen applications. And thanks to the pump’s much lower maintenance costs and our FLAIR flat rate, the next three years only add about € 3,500 to the total. That's because FLAIR, the all-inclusive care-free service package, includes

• all necessary maintenance work
• all wear parts and consumables
• no additional costs for repairs
• a replacement pump delivered within 24 hours, with shipping costs covered

Total control of life cycle costs

For the user this means absolute cost certainty. A budget item you can rely on, and operation you can depend on. And Elmo Rietschle does not subject the user to special terms and conditions. So it does not matter how many shifts or operating hours per year are being run, or whether who knows what is being processed.

The VSI 300 not only makes sense in terms of cost. This cutting-edge food packaging technology also offers enormous environmental and hygiene advantages. No more oil mist, no more having to dispose of old oil. Plus: lower power consumption, and optional efficiency-class 1 motors. Sustainability that really pays off.

• Dry, contact free compression
• Oil free discharge air
• Maintenance is limited to changing the oil (1.8 L) in the gear and bearings
• No lubricant in the suction chamber
• Water cooled: low heat generation in the production area
• Connection to existing water circuits is possible
• Superior suction at 1 to 100 mbar
• Shorter evacuation times
• Final vacuum < 0.1 mbar (absolute)
• High water vapor compatibility
• No parts to wear out in the bearings
• Variable speed drive option (frequency converter)

Screw vacuum pump can replace two, sometimes three "old" vacuum pumps

This screw vacuum pump can also be used for other processes in the food packaging industry in addition to oxygen applications. In skin & shrink applications the pump has a further advantage that has enormous impact on cost - when the screw pump is used to produce a vacuum in such applications, it achieves cycle times and efficiencies that otherwise are only possible when rotary lobe pumps are used in tandem with rotary vane pumps.

Come and see for yourself

Even though rotary screw vacuum pumps featuring FLAIR will not be officially launched until the Frankfurt IFFA in May, major companies in the meat processing industry have already been testing this pump for quite some time. And then buying it! The screw vacuum pump is also a convincing alternative in challenging applications where oil lubricated rotary vane pumps do not provide adequate performance.
