The standard features of DZS pumps include stainless steel claws and a corrosion-resistant pump chamber, allowing reliable operation even under difficult conditions.
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 controller operates the multiple claw pump unit and ensures the individual pumps are harmonized with each other in operation. The vacuum level is automatically monitored within the system and perfectly matches the process duty point.
Atlas Copco presented its new DZM high-performance multiple pump system at the Hannover Fair. These multiple dry claw vacuum pumps offer a durable, reliable solution for a variety of applications – from packaging lines, pneumatic conveyors and clamping systems for CNC machines, to moulding machines, drying processes or central vacuum supply systems. Claw vacuum pumps use two claw-shaped rotors running in opposite directions. The rotors do not touch each other or the pump chamber. This simple principle ensures that users benefit from a high degree of performance and energy efficiency.
This also applies to the DZM units, combining 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
+ DZM 1200 VSD
With an intake volume flow between 65 and 723 cubic feet per minute (cfm). As with individual DZS claw pumps, the DZM system can create a vacuum level up to 25.8 in-HgV.
