Key features

Modular Coupling System: Patented quick-connect technology allows vessel-to-vessel connection in seconds without flanges or bolts.

Zero-Leak Double Seal: Integrated double O-ring seal with pressure-assist technology ensures perfect sealing under pressure cycling.

Space Optimization: Compact coupling design reduces overall system footprint by up to 40% compared to traditional piped systems.

Superior Hydraulic Performance: Streamlined design reduces inter-vessel pressure loss by 60-80% and eliminates dead zones.

Flexible Scalability: Add or remove vessels without system shutdown; supports series, parallel, or hybrid configurations.

Easy Maintenance: Individual vessel isolation allows servicing without draining the entire system; quick disconnect in seconds.

Cost Savings: 50-70% faster installation and up to 70% fewer connections reduce material and labor costs significantly.

Premium Material Options: Shell available in SUS 304 or SUS 316L; O-rings in Silicone, NBR, EPDM, or FKM for diverse applications.

AI-Powered supplier vetting

SummaryHangzhou Keyuan Water Treatment Equipment Co., Ltd. is described as a comprehensive water-treatment-equipment enterprise covering research and development, production, sales, and after-sales service. It produces multiple filtration, tank, softening, membrane-shell, and other stainless-steel products. The supplier reports professional technical R&D capability, 3D software design services, and broad customization options. Quality assurance and raw-material traceability are stated, but corrective-action and complaint-handling procedures have no written records. The supplier has no stated inventory, overseas warehouse, overseas agent or branch, showroom, or offline trade-show participation. Financial information is insufficient for a meaningful credibility assessment, and no customer cases or certifications are provided.

Supplier typeThe supplier is explicitly described as a professional technical supplier and as a comprehensive enterprise engaged in R&D, production, sales, and after-sales service for water-treatment equipment. Its stated business scopes also include environmental-protection equipment, membrane materials, and equipment for food, beverage, pharmaceutical, oil-refining, and chemical applications.

R&D capabilityThe supplier explicitly reports professional technical R&D capability and the ability to provide 3D software design services. Its stated R&D and production scope includes water-treatment equipment, new membrane materials, and environmental-protection equipment, supporting a positive assessment of technical innovation capability.

Production capacityThe supplier states that it researches and manufactures mechanical, precision, bag, membrane, tank, softening, and other water-treatment products, with additional equipment-manufacturing scopes across several industries. However, it reports no inventory capability and no valid manufacturing-capacity contract with an associated subcontractor; these limitations do not negate its stated manufacturing operations but constrain the evidence for flexible fulfillment capacity.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also provides 3D software design services, directly supporting a broad customization capability.

Product Q&A
