Dry multi-claw vacuum pumps

DZM 600-1200 VSD⁺ - Multi-claw Dry Vacuum pump with VSD⁺ technology

Plug & play

This concept of design greatly reduces complexity and installation costs compared to other central systems designs. The package not only consists of the pumps but also comprises the common inlet manifold and an exhaust manifold resulting in two simple pipe connections.

Low noise

Atlas Copco prides itself on offering environmentally friendly solutions and noise plays a big part. Our reputation for designing and building noise reducing canopies is renowned in the industry and comes from many years of experience in the world of compressors.

Complete controllability

Atlas Copco’s DZM-VSD⁺ multi-vacuum pump controllers allows the DZM package to start/stop and control multiple vacuum pumps simultaneously according to set working pressures. The controller comes with a built-in frequency inverter for the lead pump and the lag pumps are started with soft starters to lighten the load and lengthen the life of the pump.
