Intelligent vacuum pump series for robust processes

Atlas Copco has launched the DZS 100 – 400 VSD+ series of air-cooled, oil-free claw vacuum pumps for particularly harsh applications. 

The robust pumps increase productivity in conveying, clamping, drying processes or environmental applications due to their low energy consumption and space requirements; as well as handling of pollutants.

For robust processes

Atlas Copco has equipped the three models of the DZS 100, 200 and 400 VSD+ series with corrosion-resistant materials to make them well equipped for harsh application environments. 

For this purpose, they also have a durable internal coating. The new vacuum pumps are specifically designed for a long service life and reliable, efficient operation, even under robust process conditions.

Minimised service

In addition, the design principle requires uncomplicated maintenance. For example, cleaning or replacing the pump claws does not require complex gearbox stripping and retiming. This allows quick access to the inside of the pump by service technicians or the end customer. It also simplifies maintenance processes, such as the removal of product residues. 

No new synchronisation is necessary during the subsequent assembly. This results in reduced downtime and lower service costs for the operator.

No oil-induced contamination

A VSD+ inverter drive is integrated in the motors to control the pumps. This allows the optimum performance points of the claw pump to be specifically controlled and power consumption to be reduced. This function ensures that energy is saved, and the CO2 footprint is reduced. 

Sustainability is also ensured in the immediate process environment: the completely oil-free DZS VSD+ pumps certified to ISO 8573-1 Class 0 and are completely harmless to the quality of the ambient air during operation. This eliminates the risk of oil-induced contamination and damage to sensitive applications and products in the environment.

Commissioning via App

With the newly developed VSD+ App, users have quick access to numerous parameters. Via iOS and Android devices, values such as inlet pressure, rotor speed, running hours and service intervals can be monitored and controlled at a glance in real time. 

The VSD+ App also makes it easy to commission the DZS VSD+ vacuum pump – via the three parameters target pressure, start/stop delay and stop level.

When the pump is started, the VSD+ App automatically connects via Bluetooth. Once the desired values have been entered, the innovative DZS 100 – 400 VSD+ series starts operation immediately.
