Atlas Copco launches new DZS dry claw vacuum pump range

Atlas Copco has launched its new DZS 2.2 to 6.2 kW dry claw vacuum pump range incorporating an innovative modular, easy-clean design for increased simplicity and contaminant handling capability.

The DZS range is well-suited for process applications, including pneumatic conveying, woodworking, drying, sterilising, impregnation, thermoforming, and extrusion.

It comprises three models, the DZS 065 V, DZS 150V, and DZS 300V, with nominal displacements of 45, 90, and 180cfm (1.3, 2.5, 5m3/min) respectively.

The DZS pumps offer high performance ultimate vacuum levels ranging from 50 to140 mbar(a), 28.3-25.8 Hg Vac. 

A major feature of the DZS modular concept is the segregation of the corrosion-resistant pumping chamber from the gearbox.

This allows easy access for the removal, cleaning, and re-assembly of the stainless steel claws while eliminating the need to strip and re-time gears after cleaning procedures.

The isolation of the gearbox eliminates the risk of contamination from process or gearbox oil that occurs with more traditional pump technologies.

The vacuum pumps are powered by variable speed drive (VSD)-compatible IE3 motors to provide efficient and dependable flow throughout the whole speed range.

VSD units offer significant energy savings of up to 50% compared to fixed speed equivalents.

These drives not only match response to varying demand, but also provide the opportunity to replace multiple machines with single units, which makes it possible to centralise pumps in one location and optimise system performance.

The DZS modular design allows flexibility and efficiency in terms of maintenance and lifecycle costs, specifically offering major advantages with heat dissipation issues.

Traditional claw pumps run hot, which adversely affects seals and bearings and can cause premature failure.

Atlas Copco dry claw vacuum pumps are fully certified, meeting the requirements of ISO 9001, ISO 14001, and OHSAS 18001, as verified by Lloyds of London.
