Hangzhou Boyang Motor pitches brushless gear pumps for chemical, marine and SCR systems

Hangzhou Boyang Motor Co., Ltd. is promoting integrated brushless DC gear pump systems for diesel exhaust fluid, chemical dosing and marine transfer applications. The company says the designs aim to reduce pulsation, improve chemical resistance and simplify OEM integration across industrial and vehicle platforms.

Why it matters: - Diesel exhaust fluid, corrosive chemicals and seawater can break down ordinary pump systems, causing dosing errors, leaks and downtime. - Brushless gear pumps are designed to keep fluid delivery stable while improving resistance to chemical attack and mechanical wear. - OEMs in automotive, marine and industrial equipment need compact pump systems that fit tight spaces and match specific flow and pressure targets.

What happened: - Hangzhou Boyang Motor Co., Ltd. positioned itself as a China-based supplier of brushless gear pumps for chemical, marine and automotive SCR systems. - The company said its integrated systems combine BLDC motors with external-meshing gear pump heads. - The announcement was released from Hangzhou, Zhejiang, China, on September 26, 2026.

The details: - The pump systems are aimed at diesel exhaust fluid, also known as AdBlue or DEF, in selective catalytic reduction systems. - Boyang Motor said the external gear design provides continuous liquid displacement and lower pulsation than diaphragm or reciprocating piston pumps. - The company said the pumps can be configured with 24V or 48V BLDC motors for SCR dosing applications. - Customization can include motor Kv rating and internal gear displacement to match different engine and exhaust layouts. - For marine and chemical uses, Boyang Motor said fluid-facing parts can be built from stainless steel or engineered polymers. - The company said elastomer seals such as Viton or PTFE are used for chemical inertness and thermal stability. - The brushless design removes carbon brushes, which the company said reduces conductive dust and thermal buildup. - The pumps are manufactured under ISO quality management protocols and are CE-certified. - OEM customers can specify changes to shaft configuration, mounting flange dimensions, bracket geometry, lead wire length, shielding and connector types. - Boyang Motor said it supports both internal and external brushless DC controller configurations. - The controllers use acceleration ramps intended to reduce water-hammer effects and torque spikes.

Between the lines: - The pitch centers on integration, not just pumping hardware. Boyang Motor is marketing the motor, control system and pump head as one engineered unit. - That approach is meant to reduce alignment problems and seal failures that can happen when buyers source separate components. - The company is also leaning on customization as a sales advantage for OEMs building into constrained spaces or specialized duty cycles.

What's next: - Boyang Motor is asking OEMs to share fluid properties, flow rates, operating pressure and spatial limits to receive an application-specific configuration. - The company directs product inquiries to its website: More information. - Boyang Motor also shared social channels on Instagram, Facebook and YouTube.

The bottom line: - Boyang Motor is pitching brushless gear pumps as a precision fit for harsh fluids, where chemical resistance, low pulsation and OEM customization matter most.
