• Product Advantages of Micro Gear Pump for Accurate Fluid Sampling

1. Specialized Gear Tooth Profile Design

Our proprietary gear tooth profile design delivers outstanding wear resistance and near-pure rolling meshing performance. This makes the pump ideal for gear metering pumps, metering pumps, and dosing pumps that require long-term precision and stable volumetric output.

2. Optimized Cavity Profile Design

The optimized internal cavity design allows reliable operation under varying outlet pressure conditions, including low pressure, high pressure, and short reverse pressure situations. This performance is valuable for filling pumps, micro dosing pumps, and automated transfer systems.

3. Pulsation-Free Outlet Pressure

High-precision machining and structural balancing ensure exceptionally smooth, stable, and low-pulsation fluid transfer. This is especially important for micro metering pumps, sampling pumps, and filling pumps where flow consistency directly affects accuracy.

4. Injection-Molded Gears

The gear working surfaces are produced through a high-precision single-step injection molding process without secondary machining. This ensures excellent dimensional consistency and efficient operation for micro filling pumps, dosing pumps, and compact transfer equipment.

5. High-Precision Ceramic Shafts

Equipped with high-precision ceramic shafts offering superior wear resistance and rigidity, the NP Series maintains reliable performance with abrasive liquids and under high-pressure conditions. Ideal for gear metering pumps, chemical dosing pumps, and industrial sampling pumps.

6. Extended Dry Running and Strong Self-Priming

For applications requiring vacuum creation or intermittent dry operation, the NP Series provides dependable self-priming performance and can tolerate extended dry-running periods. Suitable for micro sampling pumps, fluid intake systems, and automatic dosing equipment.

7. Multiple Motor Options

A wide range of motor configurations is available, including Explosion-Proof AC, Variable Frequency AC, Single-Phase / Three-Phase AC, Brushed DC, Brushless DC, Brushless DC with built-in drive, and Shielded Brushless DC with integrated drive. This flexibility supports customized solutions for sampling pumps, metering pumps, micro dosing pumps, and filling pumps across different industries.
