Product Overview

The NP 60 Series Micro Magnetic Gear Pump is Suofu's flagship solution for precise micro-flow fluid transfer, featuring a nominal flow range of 2.4–3.5 ml/rev and a rated flow of 0~10.5L/min. Its standout leak-free sealing technology and broad media compatibility make it a preferred choice for industries requiring safety and versatility—from automotive to food & pharmaceuticals. Unlike high-flow pumps, the NP 60 Series is optimized for low-to-medium flow demands, delivering consistent performance with minimal noise (<64 dB at 2000 rpm) and a compact design that fits space-constrained equipment. Available in two models (NP240, NP350), it meets strict hygiene and corrosion standards, making it suitable for both industrial and medical applications.

Key Features & Benefits

Leak-Free Magnetic Sealing: The magnetic drive system eliminates mechanical seals, preventing media leakage—critical for toxic, corrosive, or sterile fluids like acidic/alkaline solutions and oral liquids.

Broad Media Compatibility: Transfers water, ethylene glycol, urea, silicone oil, transformer oil, diesel, and Freon, adapting to diverse industrial needs from automotive cooling to semiconductor manufacturing.

Low Noise Operation: <64 dB at 2000 rpm, making it suitable for laboratory and medical environments where quiet operation is essential.

One-Shot Injection-Molded Gears: PEEK gears with dense working surfaces enhance wear resistance, ensuring consistent flow accuracy for micro-dosing applications (e.g., pharmaceutical drug delivery).

Compact & Lightweight Design: Small footprint fits space-limited equipment like portable medical devices and semiconductor tools.

Hygiene Compliance: Materials like SS316 Stainless Steel and food-grade FKM/EPDM O-rings meet food & pharmaceutical industry standards, ensuring no media contamination.

Application Scenarios

The NP 60 Series is tailored for industries where versatility and precision micro-flow transfer are critical:

Automotive Industry: Injects urea for SCR systems (diesel exhaust aftertreatment) and circulates cooling fluids for electric vehicle batteries.

Semiconductor Manufacturing: Delivers ultra-pure liquids (e.g., Freon, perfluorohexane) to cool and clean sensitive semiconductor wafers, avoiding contamination.

Medical Equipment: Transfers sterile fluids for diagnostic machines (e.g., blood analyzers) and drug delivery systems, complying with medical device regulations.

Food & Pharmaceutical Industries: Handles oral liquids, edible oils, and pharmaceutical ingredients with food-grade materials, ensuring product safety.

Usage Precautions & Installation Tips

Filter Requirement: Use a 400-mesh (25μm) filter at the inlet to prevent particle damage to PEEK gears. For closed-loop systems, install the filter at the outlet and verify its flow capacity exceeds the pump's rated flow by 1.5x.

Dry Running Limit: Do not exceed 1000 rpm for dry running, and limit continuous dry operation to 1 hour—exceeding these limits will damage the magnetic drive and gear surfaces.

Pipeline Alignment: Ensure pipelines are perfectly aligned with the pump's NPT3/8'' inlet/outlet to avoid uneven stress. Use sturdy pipeline supports to distribute weight, preventing pump body deformation and leakage.

Media Compatibility Check: Confirm the pump's O-ring material (e.g., FKM for oils, EPDM for water-based fluids) is compatible with the transferred medium to avoid O-ring degradation.
