Düchting HPH Pumps

Versatile Configurations and Optimised Hydraulics

The HPH pump provides flexible configuration options, with axial or radial inlets and radial discharge flanges positioned at 90° increments. This allows for easy integration into various piping systems. Replaceable rings in composite material maintain optimal efficiency and reliability, even after extended operation.

To ensure smooth operation and long service life, the HPH pump utilizes axial thrust compensation through balancing discs, a balancing drum, or a combination of both. This minimises axial forces on the rotor, reducing wear and tear on bearings and other components.

Customisation Options for Specific Needs

Düchting offers tailor-made HPH pump solutions to meet specific customer requirements.
Pump dimensions can be adapted, and impellers can be fixed with keys for applications like back-flushing.
Impeller wear rings are also available for enhanced durability.
The pump can be configured with one or two connective shaft ends for added flexibility in installation and operation.

To achieve outstanding hydraulic performance, impellers and diffusers are cast using ceramic molds, resulting in smooth surfaces that minimize friction losses and maximise efficiency.

Material Selection for Demanding Environments

It offers large versatility in material selection, with options ranging from cast iron to SUPER DUPLEX stainless steel with Pitting Resistance Equivalent numbers (PREN) above 40, ensuring long-term reliability in aggressive environments.

We carefully selects materials for the HPH pump based on the specific application and operating conditions.
