Pump Retrofit and Modernization
Technical upgrade of existing pumps: new impeller, new materials, new performance — keeping base and piping
Reverse engineering and re-rating service for existing centrifugal pumps. Our team performs dimensional survey of the installed pump (even from discontinued manufacturers), redesigns the impeller and internal parts per the new required operating point, validates by CFD and manufactures parts in our plant — keeping original casing, base and piping. Reduces replacement CAPEX and avoids prolonged downtime. Applicable to horizontal centrifugal pumps per ASME B73.1 and similar, from any manufacturer.

Reverse engineering and re-rating service for existing centrifugal pumps. Our team performs dimensional survey of the installed pump (even from discontinued manufacturers), redesigns the impeller and internal parts per the new required operating point, validates by CFD and manufactures parts in our plant — keeping original casing, base and piping. Reduces replacement CAPEX and avoids prolonged downtime. Applicable to horizontal centrifugal pumps per ASME B73.1 and similar, from any manufacturer.
Typical applications: Operating point change (new flow or head); Fluid change: compatibility with new materials; Energy efficiency gain in legacy assemblies. Configuration is adapted to the fluid, flow, pressure and operating environment of each project.
We engineer per ASME B73.1, API 610, DIN EN 24250. Complete documentation accompanies the project.
Frequent materials: CF8M / AISI 316, Ferro nodular FE-42012, Bronze ASTM B584. For severe applications, we work with special materials on request.
Digital design (CAD + CFD) → in-house manufacturing (CNC, assembly) → own hydraulic bench testing. Complete traceability from material to final part.
Yes. Every assembly undergoes hydraulic test, hydrostatic test at 1.5× operating pressure and dynamic balancing ISO 21940 G2.5. Customer receives complete report with measured actual curve.
Yes. As a direct manufacturer, we keep parts stock for base series (FBCN, FBE, FBEI, FBOT) and manufacture custom project-specific parts with traceability.
Lead times are specific to each project per complexity, material and scope. Our commercial proposal presents detailed schedule after technical analysis.
The assembly is delivered ready for field installation. Final mechanical installation is typically executed by the customer installer following our technical documentation. Assisted commissioning available as additional service.
