Product Launch | Suofu’s Self-Developed Micro Pump Family Welcomes Its Smallest Member—NP010 High-Pressure Micro Gear Pump

The NP series of micro magnetic gear pump family welcomes its newest and smallest member—the NP010 High-Pressure Micro Gear Pump. This marks a key technological breakthrough for Suofu in the field of micro-liter grade domestic micro pumps. This product further enriches the NP series product matrix, achieving comprehensive international substitution​ in core areas of high-end equipment such as life sciences, medical diagnostics, pharmaceutical & chemical industries, new energy, and aerospace, providing independent, controllable, high-performance, and cost-effective core fluid handling solutions for high-end equipment.

01. New Product Introduction: NP010

The Suofu NP010​ is a micro-liter flow micro internal gear pump. With a pump body diameter of only 20mm, the entire unit features a compact and delicate structure. Under the premise of extreme miniaturization, it perfectly balances five core performances: low flow rate, high precision, high pressure, low pulsation, and ultra-long lifespan.

Simultaneously, the NP010​ possesses significant characteristics such as zero leakage, low pulsation, wide temperature range, and strong self-priming capability, enabling stable micro-liter grade precise metering and medium transfer.

02. NP010 Materials and Parameters

1. Performance Parameters

2. Materials

Gears: Utilize high-hardness and high-strength hard alloy materials, ensuring lower wear and sustained precision over long-term operation.

Shaft: Made from high-hardness and wear-resistant zirconia ceramic, maintaining a low friction coefficient and chemical stability even with low-lubricity (water, solvents) or corrosive media.

Pump Body: Uses easily machinable stainless steel, enabling high-precision forming of complex flow channels and scalable manufacturing.

These three components work in synergy, forming the underlying technical foundation for the NP010's stable performance.

03. NP010 Product Highlights

The NP010 breaks through the industry bottleneck of "miniaturization necessitates performance compromise," featuring five key technological highlights:

1. Miniaturized Design for Compact Integration

With a pump body diameter of only 20mm, its small size and light weight make it suitable for portable devices​ and high-density integrated systems. It addresses the industry pain points of traditional pumps being too bulky and having limited installation options. It can be directly embedded into existing equipment layouts without significant structural modifications, slash enterprise replacement and costs. Its port threads are compatible with existing pipeline interfaces, and it supports various drive motors (DC brushless, stepper, servo, canned, etc.), enabling "plug-and-play" integration.

2. High-Precision Metering, Overcoming Technical Barriers

Achieves precise 0.1 ml/rev micro-liter flow transfer​ with high metering accuracy of ±0.1%. It solves the Chinese​ pump industry's bottleneck of "difficult micro-liter control,"  equal to international top-tier standards, and is suitable for applications with extremely high flow control requirements.

3. High Reliability & Long Life, Ensuring Continuous Operation

Service life exceeds 20,000 hours with clean media ( 20,000 hours under low-pressure conditions). Combined with medical-grade corrosion and wear-resistant materials, it ensures 7×24 continuous, stable operation​ with minimal maintenance.

4. High Pressure & Low Pulsation, Suitable for Complex Conditions

Handles pressure differentials up to 20 Bar, with excellent self-priming​ and gas-liquid mixed transport​ capabilities. It overcome complex work situation such as high-pressure cleaning and high-resistance pipeline transfer, improve system fault tolerance. Its operating temperature range of -20℃~60℃ provides wide temperature range adaptability for various industry environments. The inlet vacuum degree of >15 kPa(A) offers outstanding self-priming performance.

5. Multi-Scenario Adaptability + Customization, Solving Import Compatibility Issues
