In recent years, the characteristics of domestic water purifier products have become increasingly pronounced, while consumer demands have grown ever clearer.
Based on feedback from both online and offline markets, the majority of currently popular domestic RO water purifiers feature a throughput exceeding 400G. This preference stems largely from household water consumption habits, with consumers favouring products offering greater output volumes.
Increasing the flow rate of RO water purifiers necessitates considerations across multiple technologies, such as higher demands on the core component—the booster pump. As motor speeds accelerate and water flow increases, noise levels correspondingly rise. Due to inertia, the compression and friction of the diaphragm can also lead to pump pressure loss and water leakage.
For users, excessive noise during operation significantly diminishes the user experience. Given that water purifiers comprise multiple components, noise originates not only from the pump but also from other parts.
How can noise be minimised while maintaining high throughput? How can manufacturers be fully supported in comprehensive testing to optimise product performance? These represent pressing challenges for RO pump manufacturers.
As a specialist enterprise dedicated to independently developing RO pumps for pure water systems, Foshan Peili Electrical Technology Co., Ltd. has made continuous investments in factory space, automated equipment, specialised testing laboratories, and anechoic chambers. This commitment aims to enhance hardware capabilities and apply professional expertise to resolve industry challenges. These initiatives demonstrate Peili Electrical’s confidence in the future development of the water purification sector and underscore its determination to continually strengthen its competitive edge.
Records indicate that Foshan Peili Electrical Technology Co., Ltd., established in 2014, specialises in the independent development of RO pumps for reverse osmosis water purifiers. Following multiple upgrades and renovations, the company now occupies a 5,000-square-metre facility housing key production workshops for injection moulding, sheet metal fabrication, and final assembly. With multiple assembly lines and over 200 production staff, it possesses an annual production capacity of 2 million RO pumps. Guided by a customer-centric approach, the company strictly adheres to ISO9001 quality management systems in production. It perpetually pursues technological and managerial innovation, consistently delivering high-quality, cost-effective products and services to its clientele.

Peili Noise Chamber Unveiled
Recently, a reporter from HC Water Purification Network had the privilege of conducting a comprehensive tour of Peili Company, gaining first-hand insights and experiencing the noise laboratory at close quarters.
According to Peili test personnel, the noise laboratory—also known as a semi-anechoic chamber—primarily provides a semi-free acoustic field space for acoustic testing. It is chiefly used for noise testing and spectral analysis of products such as water dispensers and water purifiers, along with their components, during operational conditions. This ensures product noise metrics comply with design specifications.
The establishment of Peili’s noise chamber primarily addresses noise issues in high-flow RO pumps. It also enables comprehensive testing of complete units for clients, employing specialised data and spectral analysis to identify noise sources and propose remedial solutions, thereby enhancing the overall user experience of high-flow water purifiers.
It is understood that to overcome this noise challenge, Peili established a dedicated new department as early as 2018 – the Complete Unit Matching Department. This division specialises in identifying noise sources for collaborative clients, working with all components within the complete unit to minimise noise. Currently, with this specialised noise laboratory and professional testing system, Peili delivers tangible results for clients – achieving noise reduction of over 20% in matched complete units compared to previous models.
Hardware Testing Laboratory Ensuring Quality
In addition to the noise chamber, Peili has established a specialised hardware testing facility primarily dedicated to conducting comprehensive safety assessments on pump components and assemblies. This includes subjecting equipment to over 100,000 cycles of hydraulic shock and water hammer testing under specified conditions, alongside high- and low-temperature evaluations to verify material weather resistance and the pumps’ performance under abnormal operating conditions.
Peili possesses high-precision instruments rarely found within the industry. Its imaging data measurement equipment analyses and verifies component structural data, continuously conducting failure mode analysis to fully safeguard product performance and quality.
Smart Workshop Enhances Efficiency
With intelligent applications becoming increasingly prevalent across all industries, lean manufacturing and automated production represent the future direction for enterprises seeking to enhance efficiency and ensure quality assurance. Since its establishment in 2014, Peili has consistently pursued smart manufacturing as its developmental focus, investing in automated production equipment to minimise human error and elevate RO pump quality to a more stable state.
The implementation of automated production lines has significantly enhanced Peili’s manufacturing efficiency and cost control. The company’s production workshops integrate smart manufacturing principles throughout all stages, including pump pre-assembly, final assembly, and automated testing. Workers operate under the guidance and assistance of automated equipment execution systems to perform tasks such as part retrieval, assembly, and testing. This approach substantially boosts production efficiency, minimises human error, and ensures consistent product quality and stability.
New Product Launch Innovation Never Stops
The pandemic has introduced greater uncertainty to the development of China’s manufacturing sector. Rising raw material costs coupled with falling end-user prices have placed increased pressure on water purification enterprises. Despite these challenges, Peili has maintained robust R&D capabilities and creativity, continuously launching products with enhanced competitive advantages.
Peili New Product: 800G-1200G High-Flow RO Pump
Since the beginning of this year, Peili has successively launched 600G, 800G, and 1200G high-flux RO pump products, precisely meeting the market demand for high throughput and compact size.
Peili New Product: 800G High-Flow RO Pump
The new Peli product features four-wheel drive technology, delivering enhanced power, robust and sustained performance, consistent flow without attenuation, reduced noise levels, and extended service life.
Looking ahead, Peli will continue to strengthen its core capabilities and smart manufacturing capacity. Collaborating with leading domestic research teams, we remain attuned to market demands to elevate product quality. With first-class quality, we serve first-class customers, providing consumers with premium water purification solutions.
