SINOR holds a complete set of national, provincial and industry certifications that validate our manufacturing standards, financial credibility, innovation capability, and quality management system. Each certificate below is issued by the relevant Chinese authority and remains valid as of the latest renewal.
English-issued ISO 9001:2015 quality management system certificate by CFL Certification Center for Hunan Sinore Precision Machinery Co., Ltd. The certified scope covers the production and sales service of single screw pumps, aligned to GB/T 19001-2016 / ISO 9001:2015 requirements with CNAS-accredited certification mark.
Quality Management System certified to GB/T 19001-2016 / ISO 9001:2015 by Beijing Zhongwulian United Certification Center. Covers the production and sales of progressive cavity pumps and their spare parts, ensuring traceable quality control from incoming material inspection through final performance testing.
Utility model covering a wrap-and-stabilize fixation structure for progressive cavity pump bodies. Improves rotor alignment under high-pressure operation, reduces vibration, and extends service life of pump-barrel mounting in industrial PCP installations.
Invention patent for a multi-stage pre-swirling micro progressive cavity pump and its operating process. Introduces pre-swirling flow conditioning to enhance volumetric efficiency and reduce wear in micro-flow PCP applications such as precision metering.
Utility model covering an improved stator-rotor cavity geometry for progressive cavity pumps. Optimizes sealing-line contact and pumping-chamber volume to deliver higher flow consistency and lower pulsation in demanding transfer applications.
Utility model for an enhanced shaft sealing structure on progressive cavity pumps. Improves sealing reliability under abrasive and high-solids media, reducing leakage and maintenance frequency in wastewater and chemical-service installations.
Utility model covering a redesigned inlet/outlet pipe connection for progressive cavity pumps. Simplifies field assembly, improves seal integrity under thermal cycling, and enables faster maintenance turnaround in OEM and end-user installations.
Utility model for a progressive cavity pump design that enables easy stator replacement. Reduces stator-change downtime from hours to minutes, significantly lowering lifecycle maintenance cost for high-wear applications such as sludge dewatering and abrasive slurry transfer.
Officially recognized as a National High-Tech Enterprise by China’s Ministry of Science and Technology, Ministry of Finance, and State Taxation Administration. Confirms sustained investment in R&D, independent intellectual property, and conversion of innovation into commercial fluid-handling products.
China’s highest commercial credit rating for enterprises, jointly supervised by the People’s Bank of China and the State Administration for Market Regulation. Validates SINOR’s contract performance, financial soundness, and trustworthy business conduct across two decades of operation.
Designated as a “Specialized, Refined, Differentiated, and Innovative” (Zhuanjing TeXin) Small and Medium Enterprise by the Hunan Provincial Department of Industry and Information Technology. Recognizes SINOR’s focused expertise in niche pump technology and leadership in precision fluid handling.
Certified as an Innovative Small and Medium Enterprise by the Hunan Provincial Department of Industry and Information Technology. Acknowledges SINOR’s continuous innovation in progressive cavity pump design, stator-rotor geometry optimization, and manufacturing process improvements.
Official Recognition Plaque awarded alongside the National High-Tech Enterprise certification, jointly presented by the Hunan Provincial Department of Science and Technology, Department of Finance, and the State Taxation Administration’s Hunan branch. Industry-standard public display of our high-tech enterprise status.
Note: All certificates are issued to Hunan Sinore Precision Machinery Co., Ltd., SINOR’s manufacturing entity. SINOR (Guangzhou) Trading Co. operates as the overseas sales and service arm under the same corporate group.
