ANDRITZ Single-stage Centrifugal Pumps S Series

Engineered for the rigorous demands of the pulp and paper industry, the S Series of single-stage centrifugal pumps delivers unwavering reliability in handling a spectrum of media, from clean filtrates to abrasive paper stocks. These pumps are purpose-built to ensure continuous operation in critical processes, focusing on maximum uptime, ease of service, and resistance to the challenging conditions of mill environments.

Core Design Philosophy: Serviceability and Durability

A key advantage of this pump series is its user-centric design, which prioritizes operational economy over its entire lifecycle.

Maintenance-optimized Architecture: The pumps feature a back pull-out design. This allows for the entire rotating assembly—including the impeller, shaft, and bearings—to be removed quickly and easily without disturbing the pump casing or the connected piping. This drastically reduces maintenance time and labor costs.
Application-Tailored Impeller Selection: The series offers a choice of open, semi-open, or closed impellers. The open impeller design is particularly effective for stock with suspended solids, minimizing clogging and reducing axial thrust, while other designs optimize efficiency for cleaner or more abrasive media.
Robust Sealing Solutions: A modular sealing chamber accommodates a wide array of sealing arrangements, from standard gland packings to advanced single, double, and cartridge mechanical seals. This flexibility ensures the perfect seal for any specific duty, whether handling hot water, aggressive chemicals, or fibrous slurries.
Engineered for Longevity: Critical wet-end components are available in a range of wear-resistant materials, including various grades of stainless steel, duplex, and super duplex alloys, to combat corrosion and erosion, thereby extending service intervals.
