Reliable Performacne Under High Pressure
Self-Priming Capability
Our micro gear pumps start smoothly without needing to be pre-filled. They can run briefly dry at startup without damage, but running dry continuously will cause harm and should be avoided.
Micro Gear Pump Series From CHENHUI
CHENHUI’s micro gear pumps are reliable fluid handling solutions for various industries. Engineered for precision, these compact pumps ensure consistent flow in lubrication, cooling, and chemical systems.
Our pumps include equal-sized driving and driven gears. These gears rotate in opposite directions, trapping fluid between the teeth and pushing it toward the outlet. The external magnet delivers torque from the motor. The internal magnet receives this torque and drives the gear inside the sealed chamber. Together, they enable contactless, sealed, and efficient power transmission.
Ideal for applications requiring reliable and efficient fluid circulation, our pumps are designed to operate smoothly with low maintenance, even in tough environments. With precise flow control, low energy consumption, and minimal noise, they are perfect for handling oils, coolants, and chemicals.

Materials Used in Micro Gear Pumps
CHENHUI micro gear pumps feature stainless steel bodies for strength and corrosion resistance. The gears are made of durable PEEK to withstand wear and chemical exposure. Shaft options include 316L stainless steel, ceramic, tungsten steel, and titanium alloy to meet diverse application demands.
- Stainless steel provides solid mechanical strength and excellent resistance to corrosion. This ensures the pump can operate reliably in harsh chemical environments without degrading over time.
- PEEK (Polyetheretherketone) is a high-performance thermoplastic known for its exceptional mechanical properties. PEEK is incredibly strong, resistant to wear, and able to withstand extreme temperatures and harsh chemicals. In a gear pump, this means the gears will last longer without degrading, even under continuous use.
- For the shaft, 316L stainless steel offers good corrosion resistance, ceramic provides high hardness and wear resistance, tungsten steel is tough under mechanical stress, and titanium alloy combines strength with light weight for specialized applications.
Magnetic Coupling in Micro Gear Pump
If transferring power from the motor to the pump’s gears uses a physical shaft connection, leaks where the shaft passes through the pump casing. To solve this, micro gear pumps use magnetic coupling — a clever method that transfers power without any direct contact.
Magnetic coupling works with two sets of magnets: an outer magnet and an inner magnet. The outer magnet is fixed on the motor shaft. When the motor spins, it turns the outer magnet. Inside the pump, the inner magnet is attached to the gear shaft. The magnetic force between the two magnets causes the inner magnet to spin in sync with the outer magnet.
Magnetically coupled pumps are commonly used in industries where leakage is a concern, such as chemical processing, pharmaceuticals, and food production. They are also more efficient, as there is minimal wear on the components, and they require less maintenance compared to pumps with mechanical seals. These pumps are also highly reliable and can handle hazardous and volatile liquids with ease, making them ideal for sensitive applications.
key benefits:
- Leak-Free Operation: Magnetic coupling eliminates the need for shaft seals, effectively preventing leaks. This is crucial when handling hazardous, corrosive, or sensitive fluids.
- Reduced Wear: Without a direct mechanical connection between the motor and pump, there is less friction and wear on parts. This extends pump life and lowers maintenance costs.
- Reliable Power Transfer: While magnetic coupling avoids mechanical contact, it still provides stable and consistent power transfer, ensuring smooth pump operation even under demanding conditions.
- Quiet and Stable Operation: Pumps with magnetic coupling run quietly and with minimal vibration, improving overall reliability and user experience.
- No Shaft Seals Required: The absence of shaft seals means less downtime due to seal replacement, increasing operational uptime and reducing maintenance efforts.
