Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.
Commonly used trade names and technical identifiers for Feedwater Pump.
This component is essential for the following industrial systems and equipment:
| pressure: | Up to 200 bar (2900 psi) for standard models, higher for specialized units |
| flow rate: | 5 m³/h to 5000 m³/h depending on pump size and configuration |
| temperature: | 0°C to 120°C (typical), up to 180°C for high-temperature designs |
Indicative industry ranges for design and RFQ preparation. Confirm the exact figures and applicable standard with the manufacturer before specifying.
Quoted from the published standard.
1 company lists this product among what they make. Company figures are quoted from each company's own website; every card states where the relationship came from.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
According to the directory reference, the flow rate range is 5 to 500 m³/h, but the exact value must be selected based on boiler capacity and confirmed with the manufacturer.
Common materials include cast iron, stainless steel, and bronze. The choice depends on feedwater corrosiveness and temperature; for corrosive feedwater, stainless steel 316 is often specified.
Hydraulic performance is typically verified per ISO 9906, and motor performance per IEC 60034. These standards serve as procurement references, not certification proof.
Motor power should be matched to the pump duty point, considering flow, head, and efficiency. The reference range is 0.75 to 250 kW, but the actual requirement must be calculated for your specific system.
