Düchting HPE Pumps

Advanced Design for Optimal Performance

The HPE pump incorporates wear rings made from a carbon fiber-filled PEEK composite material.
This allows for smaller clearances while maintaining exceptional reliability and efficiency.
An intermediate discharge flange is also available for added flexibility in piping configurations.

To ensure smooth operation and extended service life, the HPE pump offers a choice of anti-friction or sleeve bearings, with forced lubrication available as an option.
Jacket or shaft seal cooling can also be implemented to further enhance performance and longevity in high-temperature applications.

Tailor-Made Solutions for Specific Needs

Düchting understands that every application is unique and offers tailor-made HPE pump solutions to meet specific customer requirements.
Pump dimensions can be adapted, and shaft sealing can be achieved through a stuffing box or mechanical seal, providing flexibility in design and operation.
Axial thrust is effectively managed by a balance disk or balancing drum, minimising wear and tear on critical components.
All wear parts are designed for easy replacement, simplifying maintenance and reducing downtime.

Material Versatility for Diverse Environments

The Düchting HPE pump offers exceptional versatility in material selection. It can be manufactured in a wide range of metals, 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.
