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.
The flow rate range for proportioning pumps is typically 0.1 to 50 L/h, depending on the model and configuration. The required flow rate should be selected based on the dosing capacity needed for your application.
Wetted materials can include 316L stainless steel, PTFE, ceramic, and EPDM. The choice of material depends on the chemical compatibility and the fluid being handled. Always verify material suitability with the manufacturer.
The steady-state accuracy at nominal flow is ±0.5%, and repeatability is ±0.25%. These values are reference ranges and should be confirmed for the specific model and operating conditions.
The operating pressure range is 1.0 to 1.6 MPa, and the operating temperature range is -20 to 80°C. Above 80°C, seals may degrade. Verify these limits with the supplier.
