Compare the published product scope and source details, then include your specifications and quantity in an enquiry.
11 companies list this product among what they make. Company figures are quoted from each company's own website; every card states where the relationship came from.
The official QDV metering pump page lists maximum flow of 85–1104 L/h, discharge pressure 3–10 bar, 48–116 strokes per minute, 0.2–1.1 kW motors, 20–100% adjustable flow, 5% metering accuracy, and handling of high-viscosity liquids of 500–3000 cP; the About page on the same domain describes a maker of corrosion-resistant chemical pumps and filters, with a contact address in Houjie, Dongguan. Proportional dosing requires multiple pumps or a control system.

Ask for use case, specification boundaries, supplier type, and RFQ preparation information for this product.
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.
