Overview


The Low Noise Full Form EC Motor is a high-precision solution designed for dosing pump systems, combining ultra-quiet operation with precise speed control for chemical and fluid handling applications. Engineered to meet the strict requirements of pharmaceutical, food, and water treatment industries, this motor ensures accurate fluid metering while minimizing noise and vibration.


Features


Ultra-Low Noise Design: Magnetic gearless drive and balanced rotor achieve noise levels ≤40dB, making it the quietest EC motor in its class (20% quieter than competing models).

Precision Speed Control: Encoder feedback system enables 0.1% speed stability (±0.05 RPM at 1000 RPM), critical for precise dosing in chemical injection and water treatment processes.

Hermetic Sealing: IP65-rated enclosure with double-lip seals prevents fluid ingress, suitable for wet environments and corrosive chemical applications.

Energy-Efficient Operation: IE5+ efficiency with 90% power conversion, reducing energy costs for 24/7 pump operations in industrial plants.

Compact Form Factor: 30% smaller than equivalent AC motors (frame size 63-100mm), fitting into tight pump installations without compromising performance.


Application


Ideal for precision fluid handling, this motor is used in:

Pharmaceutical Dosing: Accurately meters active ingredients in drug manufacturing, ensuring batch consistency and regulatory compliance (FDA, cGMP).

Water Treatment Plants: Drives metering pumps for chemical injection (flocculants, disinfectants), maintaining precise flow rates in water purification systems.

Food & Beverage Industry: Powers pumps for syrup, flavoring, and paste handling, preventing contamination with hermetically sealed components.

Laboratory Equipment: Provides smooth, vibration-free operation for analytical instruments and microfluidic systems requiring low-noise environments.


Why Choose Us


Precision Leadership: Patented encoder technology ensures repeatable dosing accuracy (±0.5% of full scale), exceeding ISO 2858 pump performance standards.

Material Compatibility: Offer stainless steel shaft and PEEK bearings for resistance to aggressive chemicals (pH 2-13), expanding application in harsh fluid environments.

Compliance-Driven Design: Certified to NSF 61 (water contact) and ATEX (explosive environments), ensuring safety in regulated industries.

Engineering Support: Collaborate with pump manufacturers to develop custom motor-pump integration solutions, optimizing performance for specific fluid properties.
