Constant Flow Pump-Precision Dosing for Laboratory and Analytical Applications
2026-09-29
When Constant Flow Is Not Optional
Peristaltic pumps pulse. Syringe pumps run out. Gravity feed is unreliable.
The RZ-10004F delivers what laboratory dosing actually needs: constant, pulse-free flow under pressure.
It's a digital constant flow pump built around an innovative stainless steel embedded PTFE design. This combination delivers what ordinary pumps cannot: corrosion resistance and high pressure resistance in one instrument.
Built for the Fluids That Matter
| Your Challenge | RZ-10004F Answer |
|---|---|
| Corrosive reagents | Stainless steel embedded PTFE – compatible with acids, bases, and solvents |
| High pressure dosing | 0~4 MPa working pressure – feeds pressurized systems directly |
| Ultra-low flow rates | 0.1~100 ml/min – precise control from micro to moderate flow |
| Pulse-free delivery | Micro pulsation design – stable flow for sensitive reactions |
| Viscous media | Handles viscosity up to 100 cps |
| Multiple volume options | 0-20 / 100 / 200 ml – choose the range that fits your application |
| Easy operation | Touch screen control – intuitive, fast, precise |
| Long service life | Automatic cleaning function – extends pump life, saves cost |
Why Constant Flow – Not Peristaltic or Syringe
| Pump Type | Limitation | RZ-10004F Advantage |
|---|---|---|
| Peristaltic | Pulsating flow, tubing fatigue, flow drifts as tubing wears | Micro pulsation, no tubing wear, stable over time |
| Syringe | Limited volume, requires refill, not continuous | Continuous operation, no refill interruption |
| Gear pump | Difficult to control at low flow, internal leakage | Precise low-flow control, corrosion-resistant wetted path |
| Gravity feed | Flow rate changes with liquid level, unreliable | Constant regardless of reservoir level |

One Question
Would you rather babysit a pulsating pump – or trust a constant flow?
Pulsation disturbs reactions. Drift ruins calibration. Refilling interrupts experiments.
Constant flow lets you focus on the science – not the pump.
The RZ-10004F gives you the stability you need.
