These vacuum pumps from Atlas Copco provide reliable, oil-free operation, as well as designed with enhanced coatings to extend the lifespan of critical components.
Atlas Copco has incorporated cutting-edge coating technology in its DZS 600 VSD+ and DZS 1200 VSD+ dry claw vacuum pumps, setting a new benchmark for durability and performance in industrial applications.
One of the standout features of the DZS VSD+ series is the PEEKCOAT coating. This advanced coating is applied to process-wetted parts and rotors, offering exceptional protection against wear, corrosion, and harsh environmental conditions. The PEEKCOAT technology ensures that the pumps maintain peak performance over time, even in demanding applications, reducing maintenance needs and downtime. The result is a longer operational life, making these pumps a cost-effective and sustainable solution for industries that require high reliability and minimal maintenance.
“The DZS VSD+ are simple and modular in design. They consist of the pump and gear chambers, which are separated by seals. Their energy-efficient, low-wear operation is based on a special coating of the wetted parts and rotors as well as their simple operating principle. Two claws rotate contactless in opposite directions in the pump housing. This draws air into the pump chamber, compresses it and expels it again under pressure. In the gear chamber, two gear wheels synchronize the claw rotation. The non-return valve in the inlet flange prevents air from flowing back into the vacuum chamber when the pump is switched off. The pumps are driven directly by a flange-mounted motor via a coupling,” has stated Ahmed Elshaffie, the responsible product manager.
In addition to the PEEKCOAT, the DZS VSD+ models also come equipped with several other innovative features aimed at optimising performance and ease of use. The vacuum relief valve prevents overheating during prolonged operation at ultimate vacuum levels, while the inlet non-return valve isolates the pump from the process when switched off, further enhancing reliability. The integrated VSD+ inverter drive regulates the pressure setpoint, contributing to energy-efficient operation.
These advanced coatings, combined with the pumps’ energy-efficient operation and user-friendly control features, make the DZS 600 VSD+ and DZS 1200 VSD+ vacuum pumps an excellent choice for applications where durability, performance, and sustainability are paramount.
