An activity built on the ability to create specific hydraulics, tailored to the particular requirements of client processes.
From a client specification: impeller, volute, diffuser.
From securing the need to the study report.
Required performance and environmental constraints.
Using dedicated in-house engineering tools.
Performance and geometry validated with the client.
Curve stability, critical parameters secured, efficiency.
Impeller CAD model and predicted performance.
Traceability of design choices and knowledge capitalisation for the client.
Centrifugal impellers, volutes, return vanes, diffusers.
Propellers.
Design of a new centrifugal impeller fitting into an existing pump casing, for seawater desalination.
1700 m³/h – 18 m – NPSHr < 4.2 m – variable speed operation possible.
Space constraints: reuse of the existing volute (wear ring positions, water passage, suction eye diameter) and of a manufacturer's “standard” bearing frame (shaft diameter).
Performance assessed against macroscopic indicators (NSS, Makay, Europump, CETIM…) and 1D pre-sizing relative to the existing hydraulic.
Geometry meeting the duty and fitting within the imposed envelope, using dedicated tools (~6 iterations).
Intermediate design review, adjustment of input data and possible performance trade-offs.
Verification over the extended operating range, securing of critical parameters (NPSH here) and loss-distribution analysis for efficiency.
Impeller CAD model and predicted performance curve.
Design review, traceability of choices and capitalisation for the client.
Offered in response to client demand.
From specification analysis to the study report, Pump System designs the hydraulic suited to your process.
