Precision Micro Gear Pump & 0-10.5L/Min

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.

The NP 60 Series Precision Micro Gear Pump 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.

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.

FAQ-10.5 L/min Micro Magnetic Gear Pump

What is the difference between NP240 and NP350?
NP240 provides 2.4 ml/rev and up to 8.2 L/min, while NP350 provides 3.5 ml/rev and up to 10.5 L/min.

Can the NP60 pump handle high-viscosity liquids?
The series supports liquids up to 20,000 cps under suitable operating conditions. Actual flow and motor selection depend on viscosity, pressure and speed.

Can the NP60 run dry?
Limited dry running is supported under specified speed and time conditions. Confirm operating limits before continuous dry-running applications.

What motors can be used with the NP60?
BLDC, AC and servo motor configurations are available depending on flow-control and integration requirements.

Which seal material should I choose?
Seal selection depends on the conveyed fluid and temperature. FKM, EPDM, PTFE, FVMQ, CR and FFKM options are available.
