A micro magnetic gear pump is a compact positive displacement pump. Its core lies in the magnetic coupling: the motor drives the external magnet rotor, which, via magnetic force coupling, synchronously rotates the internal magnet rotor and the drive gear sealed within the pump housing, thereby driving the driven gear in meshing transmission. This design achieves completely leak-free sealing.

1) Zero Leakage: Magnetic drive eliminates shaft seal leakage points.
2) High Pressure: Capable of generating differential pressures up to 20 bar at low flows.
3) Long Service Life: Non-contact torque transmission minimizes wear.
4) Dry Run Tolerance: Special materials and design allow tolerance to short-term dry running.
5) Easy Precise Control: Linear relationship between flow rate and rotational speed.

Wide flow range (0.1-26 ml/rev), high working pressure (20-40 Bar), broad operating temperature range (-120°C to 150°C), extended dry running capability (>100 hours), long service life (>20,000 hours), and strong self-priming capability.

No dynamic seals, hence no risk of leakage; reduced wear and long service life; low noise; easy disassembly and maintenance; completely sealed pump body prevents potential contamination and adapts to more working conditions.

The flow rate depends on the rotational speed and differential pressure. You need to provide the required operating flow range, outlet pressure, and liquid viscosity. We will select the suitable model based on performance curves. Please note, the pump's actual flow rate is the theoretical flow rate minus internal leakage, which increases with higher differential pressure.

The gear pump generates a "Differential Pressure". Outlet Pressure = Inlet Pressure + Pump Generated Differential Pressure. It is essential to ensure that "Inlet Pressure + Required Differential Pressure" is less than the pump's Maximum Allowable Working Pressure.

1) Flow Rate: High-viscosity liquids reduce internal leakage; under the same speed and differential pressure, the actual output flow is greater than for water.
2) Power: High-viscosity liquids increase rotational resistance, requiring a larger motor power, and it is advisable to reduce the speed to prevent cavitation and excessive energy consumption.
3) Temperature Rise: High shear may cause temperature-sensitive liquids to degrade.

Yes. Our products consist of multiple components. Each component can be configured with suitable acid/alkali-resistant materials based on specific working condition requirements, enabling effective resistance to specific acid or alkali media.

Yes, but extreme caution is required. Due to the extremely small internal clearances (tens of microns), particles can easily cause jamming or wear. We strongly recommend installing a 300-400 mesh filter at the pump inlet. The filter itself must be compatible with the liquid and have sufficient flow area to prevent excessive pressure drop.

The standard operating temperature range is -90°C to 150°C. Non-standard customization can extend this range to -120°C to 150°C.

It can handle dialysate, liquid urea, anhydrous alcohol, ethylene glycol, aviation kerosene, silicone oil, lubricating oil, transformer oil, ammonia water, sodium hydroxide, sodium hypochlorite, ozone and other disinfectants, Freon, fluorides, and other media.
Our products consist of multiple components. Each component can be configured with suitable specialized materials resistant to specific acids or alkalis based on working condition requirements. Please consult sales for specific material compatibility.

Inlet Pipe: Should be short and straight, with a diameter not smaller than the pump port. Liquid flow velocity should preferably not exceed 1.5 m/s.
Outlet Pipe: Appropriately increasing the pipe diameter can save energy. The pipeline should be equipped with a safety valve to prevent damage from dead-head pressure.
