Atlas Copco Launches Efficient DZS Range of Dry Claw Vacuum Pumps, with Low Lifecycle Costs


DZS 150
Atlas Copco has developed a new dry claw vacuum pump to add to their portfolio, the DZS. Suitable for many applications, from central systems in hospitals to pneumatic conveying, CNC routing or milking parlors - the DZS is a durable, reliable solution. Claw vacuum pumps offer non-contact and dry pumping chambers with high performance and power efficiency, based on simplicity.

When Atlas Copco, the first company to innovate multi-claw technology for compressors, acquired Edwards, experienced at bringing claw technology to vacuum applications in the high tech electronics industry, the combined knowledge and experience of these two companies lead to innovative market leading design resulting in efficient and reliable products.

Manufactured on the fundamentals of Atlas Copco compressor design, these pumps feature innovative construction materials and coatings. With vacuum pumps most of the process gasses go through the pump; this has a tendency to cause premature failure which can be catastrophic. The DZS however features stainless steel claws and a corrosion resistant pumping chamber as standard - for reliable operation even in harsh conditions.

After a process upset, unless you remove the claws a full clean cannot be guaranteed; removing the claws results in a retiming of the gears which in turn requires the gearbox to be stripped –a time consuming task. However, the new DZS design offers removable claws which are easy to clean, change seals and reassemble without touching the drivetrain, saving a massive amount of downtime and expense. The modular design of the pumping chamber, gearbox and silencer results in a simple to manage pump that can be partially replaced rather than wholly scrapped in the case of major failure due to process upsets.

“We have worked for many years with claw technologies within the compressor and vacuum industries, and many thousands of reliable machines gives us a great reputation and affords us a wealth of knowledge and experience with such technologies,” commented Koen Lauwers, Vice President Industrial Vacuum at Atlas Copco. “This is a pump built on simplicity and durability that will be with you for life.”
