Atlas Copco launches new multiple dry claw vacuum pumps
24 April 2017
A powerful combination
The new DZM series from Atlas Copco is a multiple pump system offering high-performance plug-and-play solutions that are easy to install and operate. Multiple claw vacuum pumps combine proven components from compressor systems with the simple and efficient technology of DZS dry claw pumps.
This simple principle ensures that users benefit from a high degree of performance and energy efficiency. This also applies to the DZM units, which combine between two and four DZS claw vacuum pumps, depending on the application, in a single compact housing. Atlas Copco’s sturdy, durable DZS pumps are single-stage oil-free units with air cooling, and require very little maintenance even in arduous conditions. One of the pumps in each DZM unit has a variable speed drive, allowing the vacuum to be adapted precisely to the customer’s requirements. This dramatically improves efficiency by reducing the power required and therefore reducing cost of ownership and contributes to saving the planet.
The space-saving vacuum systems are available in three sizes: DZM 600 VSD, DZM 900 VSD and DZM 1200 VSD, with an intake volume flow between 112 and 1230 cubic metres per hour (m3/h). As with individual DZS claw pumps, the DZM system can create a vacuum level up to 140 mbar(a).
High performance with low life cycle costs
The standard features of DZS pumps include stainless steel claws and a corrosion-resistant pump chamber, allowing reliable operation even under difficult conditions. “Process gases flow continuously through vacuum pumps, which may result in premature failure of the pump,” says Christoph Angenendt, Industrial Vacuum Communications Manager with Atlas Copco. “It is therefore very important to select suitable materials and coatings.”
The claw technology used in the DZS series also offers the advantage that, despite the very tight clearances between rotors and casing, there is no contact between these components and the pump is therefore virtually free from wear. The result is a reliable pump combining longevity with minimum maintenance expenses and high performance with low life cycle costs. Thanks to the anti-noise hood and smart details such as vibration-reducing feet and an integrated exhaust silencer, the DZS pumps are among the quietest claw pumps on the market; they therefore contribute to a pleasant working atmosphere.
Compact system solution
“Our new DZM multiple pump system is based on the simple design principles of our compressors,” says Angenendt. “We install our high-performance DZS pumps under an anti-noise hood together with all the components required and offer our customers a system solution that is both compact and intelligent.” The sturdy housing protects the pumps, reduces noise levels and heat and contains all the technology required for operation in a single box. In order to protect the heat-sensitive electronics, “hot” and “cold” components are installed separately from each other. The side walls are removable, allowing rapid access and facilitating maintenance.
