Efficient Pumps with Minimal Lifetime Expenses
Atlas Copco’s latest dry claw pump series sets a new standard in the industry, leveraging innovative engineering to deliver unmatched efficiency and durability. Built on proven compressor design principles, these pumps combine simplicity, robustness, and superior contaminant tolerance—making them an intelligent choice across diverse applications. Designed to meet the highest quality expectations, they offer a reliable, low-maintenance, and economical solution tailored to long-term performance.
Engineered for Durability
These pumps are constructed using advanced materials and protective coatings, ensuring stable operation even under demanding conditions. The design philosophy centers on longevity, with every component selected to support extended service life and consistent performance.
Simplified Maintenance Access
Featuring long-lasting bearings and seals, along with a fully isolated pumping chamber, the system allows for quick and easy cleaning—especially beneficial in cases of product carry-over. The straightforward layout enables fast access to critical components, reducing downtime and service complexity.
Outstanding Operational Advantages
Atlas Copco is committed to sustainable innovation, and noise reduction is a key focus. Drawing from decades of expertise in compressor acoustics, the pumps feature advanced sound-dampening enclosures—an industry-recognized hallmark of quiet, efficient design.
Ready-to-Operate Integration
Designed with a true Plug & Play approach, this system significantly cuts installation time and costs compared to traditional centralized setups. The complete package includes not only the pumps but also integrated inlet and exhaust manifolds—requiring only two simple pipeline connections.
All control components, including the Variable Speed Drive, process sensors, and safety systems, are housed within a thermally optimized ‘cool zone,’ enhancing both reliability and ease of use. This integrated design ensures seamless startup and dependable operation with minimal setup effort.
