3D Model Review
3D model data can be used to review pump geometry and support drawing, visualization and configuration work.
ISO PROCESS PUMP SELECTION
ISO 5199 Process Pumps for General, Wear-Resistant & Non-Clogging Service
Compare three industrial process-pump routes by service condition: AC for general process duties, DW where abrasion and erosion dominate, and DN where large solids, fibers and plugging risk drive the selection. AC is designed to EN ISO 5199 and EN 22858 (ISO 2858). Final pump selection is confirmed against the actual duty and configuration.

- Engineering review before quotation
- Existing-pump data accepted
START WITH THE SERVICE DUTY
Which ISO Process Pump Route Fits the Application?
Select by the dominant process risk first. Final configuration still depends on the actual liquid, operating point and project requirements.

ENGINEERING SELECTION LOGIC
Select by the Dominant Process Risk
A route is a starting point, not an automatic final pump selection. Final hydraulic, mechanical and project requirements must be reviewed before quotation.
| Process condition | First review route | Why |
|---|---|---|
| Clean / lightly contaminated liquid | AC | General process duty |
| Viscous liquid | AC | General process starting point; confirm viscosity |
| Fibrous slurry | AC / DW / DN review | Route depends on wear, passage and plugging risk |
| Abrasive slurry | DW | Wear / erosion is the primary risk |
| Abrasive large solids | DW | Wear is the primary risk; passage must also be checked |
| Large solids / long fibers | DN | Passage / plugging is the primary risk |
| Gas-containing process liquid | AC / DW / DN review | Depends on service type and hydraulic configuration |
| Self-priming application | Engineering review | Supported in selected brochure applications; exact configuration must be confirmed |
| Desalination | AC | Listed AC application |
PUBLISHED FAMILY RANGES
Published AC / DW / DN Family Ranges
Use these values as screening references only. They are family-level published maximums, not a guaranteed operating envelope for every size or material.
| Series | Primary duty | Capacity | Head | Pressure | Temperature |
|---|---|---|---|---|---|
| AC | General process | 11,000 m³/h | 160 m | 16 / 25 bar* | 180°C |
| DW | Wear resistant | 7,000 m³/h | 110 m | 16 / 25 bar* | 180°C |
| DN | Non-clogging | 2,000 m³/h | 90 m | 16 bar* | 180°C |
* Published family-level maximums are screening references, not a guaranteed operating envelope for every size or material. Actual allowable pressure and operating limits depend on the selected pump, material, size and configuration.
STANDARDS CONTEXT
ISO 5199 and ISO 2858 Are Not the Same Requirement
ISO 5199
Technical Requirements
ISO 5199 provides technical specifications for Class II centrifugal pumps and addresses mechanical and technical requirements relevant to process-pump service.
ISO 2858 / EN 22858
Dimensional / Designation Framework
ISO 2858 / EN 22858 addresses designation, nominal duty-point and principal dimensional references for end-suction centrifugal pumps.
AC is stated in the published product data as designed to meet EN ISO 5199 and to comply with EN 22858 (ISO 2858). The supplied source does not establish the same ISO 2858 claim for every DW or DN configuration, so standard applicability must be confirmed for the selected product and project.
ENGINEERING VERIFICATION
From Geometry Review to Hydraulic Analysis
Engineering tools support review and validation when required by the project.
02 / VALIDATE
Scan / CAD Pattern Validation
Scan data and CAD comparison can support geometry validation and component-development review.
03 / ANALYZE
CFD Hydraulic Review
Computational fluid dynamics can be used to study internal flow behavior and support hydraulic review when required by the project.
APPLICATIONS
Industrial Applications
Chemical Process
Corrosive, viscous and process liquids requiring application-specific hydraulic and configuration review.
Pulp & Paper
Fibrous media, slurry and solids-handling duties where wear and passage may influence pump selection.
Water & Wastewater
Industrial water, wastewater and solids-containing applications requiring reliable process pumping.
Oil & Gas Downstream
Selected refining, petrochemical and downstream process duties.
Metals
Abrasive and corrosive process services where wear resistance can be a dominant selection factor.
Food & Process Industries
Selected process duties where fluid properties and process requirements determine the final pump configuration.
EXISTING INSTALLATION
Replacing an Existing ISO Process Pump?
Start with the installed pump data instead of assuming interchangeability from a family name. Note the manufacturer, model, size, duty point and whether drawings or photos are available. Our engineering team will request the files during the replacement review.

FAQ
ISO Process Pump Selection FAQ
What is the difference between ISO 5199 and ISO 2858?
ISO 5199 defines technical requirements for Class II centrifugal pumps. ISO 2858 / EN 22858 defines designation, nominal duty-point and principal dimensional references for end-suction centrifugal pumps.
Which series should I start with: AC, DW or DN?
Start with AC for general process service, DW when abrasive wear or erosion is the dominant issue, and DN when large particles, long fibers or plugging risk dominate. Final selection still requires the actual duty and liquid data.
Does every AC, DW and DN configuration comply with ISO 2858?
No universal claim should be made from the current product source. The published data explicitly states EN ISO 5199 and EN 22858 (ISO 2858) for AC. Standard applicability for DW, DN and individual configurations must be confirmed for the selected project.
Can you review an existing pump for replacement?
Yes. Note the installed manufacturer, model, size, duty point and any nameplate, curve or GA drawing available. Our engineering team will request the files during the replacement review.
Are the published maximum flow, head and pressure values available on every pump size?
No. They are family-level published maximums for screening. The actual allowable operating range depends on pump size, material and selected configuration.
