DRYVAC DV450 and RUVAC WH2500: Two more application focused fore vacuum pumps enhance the product portfolio of Oerlikon Leybold Vacuum.

The new DRYVAC DV 450 now complements the already existing variants of DRYVAC pumps and systems. This new pump also combines dry screw technology with a very compact design and additional customer benefits such as extreme silent operation, low ambient temperatures and minimal cooling water consumption. The DV450 is the ‚smaller brother‘ of the DRYVAC DV650, with an optimized drive for suction speeds of 450m ³/h and an also optimized engine efficiency with only 5.3kW power consumption at final pressure. The integrated frequency converter leads to reduced installation efforts for customers with full pump protection and a large variety of interfaces. Another benefit for demanding processes is the operation at very low screw-rotor temperatures, which predestines the pumps for applications such as solar lamination, eliminating possible layers to be built-up.

Of course, all combinations with a RUVAC roots pump are possible. Arranged vertically in a standard mode, the overall plant footprint is reduced, while with a horizontal arrangement the pumps can be placed underneath the plant’s manufacturing systems.

The companies’ offering of sturdy and reliable roots pumps is now complemented by the new RUVAC WH2500 featuring highest flexibility and pump protection via operation with frequency converter. Furthermore it offers smallest footprint in an advanced design. Lowest power consumption and minimized noise and heat emission meet the requirements of innovative customers.
Due to the compact size and the reduced weight, the pump can be directly mounted onto properly sized backing pumps of Oerlikon Leybold Vacuum. This saves additional costs and reduces installation space. The full product range of WH2500 is already available. The range includes three types of different drives with internal frequency converter, external frequency converter and direct net operation.

In addition, the pump is available with two different oil fillings – either synthetic oil or PFPE oil.
The new WHU2500 with by-pass valve features a new motor concept which helps to reduce pump down time in short cycle applications dramatically. This improves throughput in time critical processes.

Oerlikon Leybold Vacuum offers customers optimized vacuum solutions, driving down cost of ownership and enhancing production reliability and profitability.

Today, full system integration of all components is one of the most important requirements for the design and operation of a vacuum system posed by customers in industry, R&D and analytical business fields. The full-line vacuum portfolio offered by Oerlikon Leybold Vacuum supports all manufacturing processes within coating, metals, and other industrial applications in the rough, medium, and high vacuum regime. Pumping technologies, systems and services include components, standardized systems and fully customized vacuum solutions. The product range comprises oil sealed rotary vane and piston pumps, dry compressing and oil-free pumps, vacuum boosters, turbo-molecular, oil diffusion & cryogenic vacuum pumps, as well as standard and customized research coating systems. Repair & remanufacturing of all brands of vacuum pumps complement the vacuum portfolio.
