Methanol-to-Hydrogen High-Pressure Transfer
MPB003-series pumps transfer methanol and process liquids at up to 20 bar with zero leakage. Stable pressure ensures continuous, safe reforming for distributed hydrogen production.
- Sealless, zero-leakage magnetic drive
- Precise, pulse-free, repeatable flow
- Tailored OEM / ODM engineering
The Problem We Solve
Conventional sealed pumps struggle where Methanol-to-Hydrogen High-Pressure Transfer demands absolute reliability. Shaft-seal leakage, contamination, flow pulsation and maintenance downtime turn a small component into a system-level risk.
Leakage & Contamination Risk
Mechanical shaft seals wear and leak over time, contaminating the fluid path and forcing costly, unplanned maintenance in mission-critical service.
Unstable, Pulsating Flow
Inconsistent flow and pressure ripple undermine process accuracy, product quality and the thermal stability the application depends on.
Harsh, Continuous Duty
Aggressive media, wide temperature swings and around-the-clock operation push standard pumps beyond their reliable service life.
How Chenhui Engineers It
Chenhui engineers a sealless magnetic-drive solution around your exact duty point. Torque transmits through a fully enclosed magnetic coupling instead of a shaft seal — eliminating leakage at the source while delivering smooth, repeatable, pulse-free flow.
-
Application & Duty-Point Analysis
We start from your fluid, flow, pressure, temperature and environment to define the precise performance envelope your system requires.
-
Pump & Drive Matching
We select the right MPB pump head and pair it with a brushless, servo or stepper drive for closed-loop, programmable flow control.
-
Material & Sealing Engineering
316L, PEEK, ceramic and FKM as standard, with titanium, Hastelloy, FFKM and PTFE options for aggressive, high-purity or food-grade media.
-
Validation & Volume Production
Prototypes are tested against your acceptance criteria, then scaled through our in-house full-chain manufacturing with stable, repeatable quality.
Outcomes You Can Count On
The result is a fluid-control core your system can rely on: zero leakage, precise flow and maintenance-light operation that holds up under continuous, real-world duty.
- 0 Leakage — fully sealless magnetic drive
- ±1% Repeatable flow / metering accuracy
- 24/7 Continuous, low-vibration operation
- 20 bar Stable high-pressure transfer capability
