Flow, head, fluid, voltage
Core duty fields for transfer and chemical SKUs. Write continuous vs intermittent duty.
Tubing ID / wall
For peristaltic dosing: ID sets displaced volume; wall and duro affect occlusion life. Quote material from the fluid list.
RPM ↔ flow (formula)
Q ≈ k × RPM for a fixed tube/roller set. Confirm k on a calibrated catch — we do not publish a fake ml/rev chart.
Peristaltic pumps
See the peristaltic / dosing line selection guide and the calibration blog. Variable-flow is a SKU option, not a separate hub title. Briefing a diaphragm pump, a progressive cavity pump, a pool pump, or a pool filter instead? To pick a metering type, read the dosing pump guide. Use the checklist on that page.
采购常见问题
Is this a clothing size guide?
No. It is a pump duty and tubing brief for OEM and wholesale RFQs.
Do you publish a price list or Semrush volumes?
No. Price depends on wet end, options, and volume. We do not publish search-volume numbers.
