Boyang Motor touts low-noise brushless gear pumps for industrial dosing

Hangzhou Boyang Motor Co., Ltd. is pitching integrated brushless gear pump systems for chemical processing and automotive SCR applications, with a focus on low noise, precise dosing and corrosion resistance. The company says its motor-pump designs can help reduce pulsation, improve reliability and extend service life in demanding fluid-handling systems.

Why it matters: - Chemical processing and automotive selective catalytic reduction systems depend on precise fluid dosing, low noise and chemical resistance. - Boyang Motor is positioning its integrated motor-driver-pump approach as a way to reduce pulsation, vibration and leakage in those applications. - The company says industrial buyers can use matched configurations to improve reliability and reduce maintenance risk.

What happened: - Hangzhou Boyang Motor Co., Ltd., founded in 1998, presented its brushless gear pump platform for industrial fluid management. - The company says it has more than 28 years of manufacturing experience, 600 skilled employees and CE-certified production lines. - Boyang Motor offers motor-centric pump systems rather than standalone fluid components. - The company directs customers to its website for matched pump-motor-driver configurations and evaluation prototypes.

The details: - Boyang Motor’s brushless DC motor platforms support 24V, 36V, 48V and 310VDC inputs. - The motors can be set up with hall sensor six-step control or external sine wave PWM controllers. - The company says sine wave driving reduces torque ripple and helps produce steadier discharge flow in SCR systems. - Boyang Motor’s micro gear pumps cover displacement ratings from 0.2 to 3.5 ml/rev and flow rates from 0 to 10.5 L/min. - The pumps operate at differential pressures from 8 to 40 Bar and fluid temperatures from -120 to 150 degrees Celsius. - The company says wet-end service life exceeds 20,000 hours. - For SCR use, Boyang Motor specifies Viton or EPDM seals for resistance to 32.5% aqueous urea solution. - For mild acids or bases, the company offers PEEK, Viton or PTFE seals with stainless steel or engineering plastic casings. - Boyang Motor says its direct-coupled design places the motor and pump on a single axis and removes external couplings. - The BYMP020 and BYMP030 micro magnetic gear pump series use static O-ring sealing and magnetic drive transmission to isolate fluid from the outside environment. - The BYMP030 series handles flow up to 3 L/min at differential pressure up to 15 Bar, uses helical gears and runs on a 150W BLDC motor up to 4500 rpm. - The company says the BYMP030 produces an acoustic footprint below 60 decibels. - The BYMP020 series is a more compact design with integrated brushless motor assembly and inlet vacuum capacity reaching -0.85 Bar. - Boyang Motor says the high suction capacity supports priming and consistent dosing under restrictive intake conditions. - The company says it calibrates motor constants, back electromotive force and phase resistance to match pump-head torque-speed curves. - Engineers fine-tune PID driver settings to handle start-up friction and reduce resonance during cold starts. - Boyang Motor says it tests assemblies on simulation benches that replicate load, temperature spikes and vibration under ISO standards. - The company says it can move from motor design and engineering drawings to sample validation and mass production planning. - Boyang Motor says it responds to customer design inquiries within 24 hours. - Contact details in the release include +86 571 8687 1517 and social media links on Instagram, Facebook and YouTube.

Between the lines: - The release is less about a single pump model and more about a systems strategy: motor, drive and pump are designed together to reduce failure points. - Noise reduction and leakage control appear to be the company’s main differentiators, especially for dosing systems where flow stability affects compliance and diagnostics. - The emphasis on material compatibility suggests Boyang Motor is targeting customers that deal with corrosive or chemically sensitive fluids.

What's next: - Boyang Motor is inviting industrial equipment builders and SCR integrators to share media type, flow-pressure curves and space limits for custom configurations or prototypes. - The company appears to be using the release to generate leads for tailored pump-motor-driver packages rather than to announce a new standalone product launch. - Prospective customers can request more information through the company’s website and listed contact channels.
