What the Customer Was Up Against
Before partnering with Chenhui, this Medical & Life Science application pushed conventional sealed pumps past their limits. Shaft-seal leakage, flow pulsation, contamination risk and maintenance downtime turned a small component into a system-level liability.
Leakage & Contamination Risk
Mechanical shaft seals wore and leaked over time, threatening fluid purity and forcing costly, unplanned maintenance in mission-critical service.
Unstable, Pulsating Flow
Inconsistent flow and pressure ripple undermined process accuracy, product quality and the thermal stability the application depended on.
Harsh, Continuous Duty
Aggressive media, wide temperature swings and around-the-clock operation pushed standard pumps well beyond their reliable service life.

How Chenhui Solved It
Chenhui engineered a sealless magnetic-drive solution around the exact duty point of the system. 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 started from the fluid, flow, pressure, temperature and environment to define the precise performance envelope the system required.
-
Pump & Drive Matching
We selected the right MPB pump head and paired 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, FFKM and PTFE options selected for the specific media and purity demands.
-
Validation & Volume Production
Prototypes were tested against the customer’s acceptance criteria, then scaled through our in-house full-chain manufacturing with stable, repeatable quality.
Measurable, Field-Proven Outcomes
The result is a fluid-control core the customer can rely on: zero leakage, precise flow and maintenance-light operation that holds up under continuous, real-world duty — validated in the field and scaled to production.
- 0 Leakage incidents — fully sealless drive
- ±1% Repeatable flow / metering accuracy
- 24/7 Continuous, low-vibration operation
- 12 mo Field-validated before volume scale-up
