MPB075 Miniature Magnetic Drive Gear Pump – Leak-Free, 316 Stainless Steel, for High-Viscosity & Precision Fluid Transfer

The world's most reliable micro gear pump for demanding applications.

Introducing the MPB075 – a compact, seal-less magnetic drive gear pump built entirely from 316 stainless steel. Unlike traditional gear pumps that rely on mechanical seals (and leak over time), the MPB075 uses magnetic coupling to transfer torque through the pump wall – zero rotating shaft, zero leakage, zero maintenance.

Engineered for high-viscosity fluids, pulse-free metering, and corrosive environments, it delivers unmatched stability in EV cooling, lubrication systems, fuel handling, chemical dosing, and more.

🔧 Two Models. One Superior Design.

💡 Why magnetic + gear?

Gear pumps move thick fluids efficiently. Magnetic drive makes them safe and sealed. The result: precision + safety in one unit.

✅ Why Engineers Choose the MPB075

• ✅ Truly Leak-Free – No shaft seal = no failure point. Safe for flammable or expensive fluids.
• ✅ Handles High Viscosity – Up to 3000 cP (e.g., gear oil, silicone, syrup) with stable flow.
• ✅ Pulse-Free & Accurate – Ideal for dosing, sampling, and closed-loop circulation.
• ✅ 316 Stainless Steel – Resists corrosion from acids, salts, and chemicals better than 304.
• ✅ Long Life, Low Noise – Brushless DC motor + magnetic drive = minimal wear, <60 dB operation.
• ✅ Compact & Self-Priming – Fits tight spaces; primes automatically up to 3–5 meters.

🌐 Compatible Fluids (Thanks to 316SS + Seal-less Design)

🔌 Wiring is simple: Clear color-coded terminals included (see wiring diagram).

🛡️ Compliance Notice

This pump is designed for industrial, laboratory, and non-potable applications.

It is not certified for CE (machinery directive), FDA, UL, or ATEX.

Use only in non-explosive, non-sanitary environments.

❓ FAQ

Q: Is this a centrifugal pump or gear pump?
A: It's a positive displacement gear pump – ideal for high-viscosity and precise flow control.

Q: Can it run dry?
A: No. Like all gear pumps, it requires liquid for lubrication and cooling. Avoid dry running.

Q: Why choose magnetic drive over standard gear pump?
A: Standard gear pumps leak over time due to seal wear. Magnetic drive eliminates that risk – critical for flammable, toxic, or expensive fluids.

Q: Can I use it for food production?
A: It can handle food-grade liquids, but it is not FDA-compliant. Use only in non-sanitary or R&D settings.
