Düchting HPXU & HPXM Pumps
A Multi-Stage Workhorse for Demanding Applications
The Düchting HPXU & HPXM pumps are multi-stage centrifugal pumps engineered for heavy-duty applications in demanding industrial environments.
This ring-section design pump excels at handling contaminated, chemically neutral or aggressive liquids with up to 10% solids, making it ideal for industries like mining, mineral processing, and oil & gas.
Optimized for Efficiency and Durability
The HPXU pump features flanges positioned at 90° increments, offering flexibility in installation and piping configurations. Shaft sealing is achieved through a stuffing box or mechanical seal, catering to diverse application needs.
A key feature of the HPXU pump is its axial thrust compensation mechanism, which utilizes a balancing device with an optical or digital wear indicator.
This innovative system not only minimizes axial forces on the rotor, extending service life, but also provides valuable insights for optimized maintenance planning.
Designed for 4-pole speed operation, the HPXU pump delivers reliable performance with reduced life-cycle costs. Grease or oil lubrication options are available to suit specific requirements and further enhance durability.
Tailor-Made Solutions for Specific Needs
Düchting understands that every application is unique and offers tailor-made HPXU pump solutions to meet specific customer requirements. Pump dimensions can be adapted, and single or double inlet suction casings are available for increased versatility.
Discharge flanges can be incorporated on intermediate stage casings, providing flexibility in system design. The pump can be driven from one or both shaft ends, further enhancing adaptability.
The HPXU pump features a closed impeller with three-dimensionally curved blades for optimal hydraulic efficiency. The impeller is securely fixed with a fitting key, ensuring reliable operation and ease of maintenance.
Material Versatility
The Düchting HPXU pump offers exceptional versatility in material selection. It can be manufactured in a wide range of metallic materials, from cast iron to SUPER DUPLEX stainless steel.
Düchting carefully selects materials based on the specific application, the pumped medium, and the operating conditions to ensure optimal performance, corrosion resistance, and longevity.
