S-0.3 Micro Magnetic Drive Gear Pump
2026-09-29
When Ordinary Pumps Fail
Peristaltic pumps wear out. Diaphragm pumps pulsate. Standard gear pumps corrode.
The S-0.3 was built for the fluids that destroy ordinary pumps.
It's a micro magnetic drive gear pump with PEEK gears and a ceramic shaft. No shaft seal. No leakage path. No corrosion-prone metals in the wetted path.
Built for the Fluids That Break Other Pumps
| Your Challenge | S-0.3 Answer |
|---|---|
| Corrosive liquids | PEEK gears + SUS304 body – compatible with acids, bases, and solvents |
| Abrasive liquids | Ceramic shaft + injection-molded PEEK gears – wear-resistant, long-lasting |
| High-viscosity media | Handles 0.2~1500 cps – from water-thin to paste-thick |
| High-temperature liquids | -40~100°C working range – stable across wide temperature swings |
| Pulsation-sensitive processes | Magnetic drive gear principle – no pulsation, smooth continuous flow |
| High-pressure dosing | 0.6 MPa working pressure – feeds pressurized systems directly |
| Leak-free operation | Magnetic drive – no shaft seal, no leakage path |
| Compact installation | Miniature footprint – fits into tight equipment spaces |
Why Magnetic Drive – Not Shaft-Sealed
| Pump Type | Limitation | S-0.3 Advantage |
|---|---|---|
| Shaft-sealed gear pump | Seal wears, leaks, contaminates | Magnetic drive – no seal, no leak, no contamination |
| Peristaltic pump | Tubing fatigue, pulsation, limited pressure | PEEK gears – no tubing, no pulsation, higher pressure |
| Diaphragm pump | Pulsating flow, valve wear, limited temperature | Gear principle – smooth flow, no valves, wide temperature |
| Centrifugal pump | Cannot handle high viscosity, low pressure | Positive displacement – handles high viscosity, high pressure |

| Food and Beverage | Additive dosing, flavor injection | Hygienic materials, smooth flow |
One Question
Would you rather replace seals every month – or trust a magnetic drive?
Seals wear. Seals leak. Seals contaminate.
Magnetic drive eliminates the seal entirely.
The S-0.3 gives you the reliability you need.
