Atlas Copco DZS 100, 200 and 400 VSD+ dry claw pumps

Atlas Copco has released a robust pump designed to increase productivity in conveying, clamping, drying processes or environmental applications. The DZS 100 VSD+, DZS 200 VSD+ and DZS 400 VSD+ dry claw vacuum pumps are equipped with corrosion-resistant materials, enabling them to withstand harsh environments. For this purpose, they also have a durable internal coating.

Cleaning or replacing the pump claws does not require complex gearbox stripping and retiming, facilitating uncomplicated maintenance. Service technicians or users can remove product residues from the pump by accessing the inside of the pump, without necessitating new synchronisation during the subsequent assembly. This reduces downtime and service costs for the operator.

A VSD+ inverter drive is integrated in the motors to control the pumps, allowing users to control the performance points of the claw pump, reducing power consumption and the user’s CO₂ footprint. The DZS VSD+ pumps are oil-free, certified to ISO 8573-1 Class 0.

The range features longer-life bearings and seals, with straightforward access to the pumps’ internal mechanisms for cleaning and maintenance. The lower power consumption of the pumps also facilitates a low noise level while in use.
