ANDRITZ Single-stage Centrifugal Pumps VP Series

Engineered for the most demanding applications in the pulp and paper industry, the VP Series of single-stage centrifugal pumps sets a new standard for reliability and efficiency in handling fibrous, abrasive, and solid-laden media. These robust pumps are specifically designed to minimize clogging and reduce energy consumption, delivering superior performance in harsh processing environments.

Versatile Industrial Applications of ANDRITZ Single-stage Centrifugal Pumps VP Series

The VP Series is built to perform across a wide spectrum of industries and applications, including:

Pulp & Paper Production: Raw pulp, paper stock, wastepaper slurry, and alkali recovery streams.
Chemical & Pharmaceutical Processing: Chemical slurries, pharmaceutical intermediates, and abrasive process fluids.
Water & Wastewater Management: Effluent treatment, sludge transfer, and water supply.
Food & Bio-Products: Handling molasses, sugar syrups, and other viscous food products.
Fertilizer & Mining: Potash fertilizer slurries, coal preparation, and other mineral processing duties.

Uncompromising Design for Demanding Applications of ANDRITZ Single-stage Centrifugal Pumps VP Series

The VP Series incorporates several key design features to ensure continuous, trouble-free operation:

Advanced Impeller Design: A precision-cast, semi-open impeller with a large, non-clog channel and 3-6 vanes efficiently handles high concentrations of fibrous material. This design minimizes axial force, prevents air entrainment, and is ideal for pumping pulp, paper stock, and waste paper.
Optimized Volute Casing: The single-stage, double-volute casing structure is engineered to significantly reduce radial forces and shaft deflection, enhancing bearing life and overall mechanical stability.
Robust Material Selection: Wetted components are available in a range of durable materials including cast iron, stainless steel (304, 316L), and duplex stainless steels to resist corrosion and abrasion, ensuring a long service life.
Flexible Sealing Solutions: The pumps support various sealing arrangements, including single and double mechanical seals or traditional packing, to suit specific process requirements and minimize leakage.
Modular & Service-Friendly Construction: A innovative modular design minimizes the number of necessary spare parts, streamlining inventory and reducing maintenance downtime. The sealing arrangement allows for easy access and repair.
