Explore our heavy-duty industrial centrifugal pumps, high-vacuum systems, and precision chemical transfer apparatus engineered to minimize system downtime.
In contemporary industrial setups, fluid movement systems account for a large portion of operational energy consumption and maintenance budgets. Heavy manufacturing plants, deep-well mining operations, chemical processing complexes, and municipal utility stations demand specialized pumping systems that run reliably in aggressive settings. From low-viscosity volatile compounds to highly abrasive mineral slurries, the physical demands of fluid transport require robust, application-specific engineering.
The movement towards automated and zero-emission industrial operations has changed the technical criteria for pump manufacturers. Systems must comply with strict environmental requirements while maintaining high thermodynamic efficiency. Our customized OEM/ODM approach meets these demands by using state-of-the-art materials, optimized impeller designs, and smart sealing arrangements to prevent leakage, reduce friction losses, and extend the mean time between failures (MTBF).
Your Trusted Heavy-Duty Industrial Pump Manufacturing Partner.
Shandong Tongyi Machinery Equipment Co., Ltd. is a specialized manufacturer of vacuum pumps, water pumps, slurry pumps, and other high-grade industrial fluid handling equipment. Guided by our principles of "science and technology leading, quality-oriented, and reputation first", we focus on continuous technical development and strict production controls. Over years of development, we have built a manufacturing setup that combines initial concept development, engineering design, precision casting, machining, assembly, and performance testing.
Our production plant features modern workshops equipped with advanced processing systems, including high-precision CNC lathes, heavy-duty floor boring machines, multi-axis machining centers, and automated drilling equipment. By matching our production processes with advanced test equipment, we ensure that every pump leaving our facility meets high standards of dynamic balance, sealing integrity, and hydraulic efficiency.
Equipped with CNC machining centers, automated testing bays, and heavy floor boring machinery to maintain strict component tolerances.
From custom impeller adjustments for varying viscosities to high-alloy castings for corrosive chemical environments.
Every single pump undergoes rigorous testing, including hydrostatic pressure, NPSH verification, and vibration analysis.
A comprehensive overview of our standard and customized pump configurations built for demanding environments.
Our vacuum engineering division provides reliable solutions for gas extraction, distillation, drying, and evacuation tasks. The product line includes the SZ, SZB, SK, 2BV, and 2BEA/C series water ring vacuum pumps, which are widely used in chemical, pharmaceutical, and paper manufacturing plants. These liquid ring pumps handle incoming gas streams containing liquid droplets or corrosive vapours without damaging the internal parts.
For dry vacuum requirements, we supply the WLW vertical oil-free reciprocating vacuum pump and the GWSP series dry oil-free scroll vacuum pumps. These systems are designed for contamination-free laboratory settings, semiconductor manufacturing, and cryogenic freeze-drying processes where oil vapor backstreaming is unacceptable.
Moving heavy slurries in mining and mineral processing requires pumps that resist wear and abrasion. We manufacture the YZ/YW series vertical slurry pumps and the GMZ/ZJ series horizontal heavy-duty slurry pumps. Built with high-chrome alloys and wear-resistant elastomeric liners, our slurry pumps transport abrasive mixtures, sand, tailing muds, and mineral ores. The hydraulic design helps maintain high efficiency throughout the wear life of the wet-end components.
In petrochemical complexes and power generation installations, fluid integrity is critical. Our chemical process pumps, including the IH series, FSB fluorine plastic centrifugal pumps, and API 610 compliant process pumps (OH1, OH2, BB1-BB5, VS6), are designed to handle acids, aggressive chemicals, hydrocarbons, and high-temperature boiler feedwater. With self-balancing multi-stage designs (such as the BB4 and BB5 configurations), these systems operate under high-pressure conditions while keeping axial forces low and shafts stable.

To serve diverse industrial sectors worldwide, our pumps comply with international performance and safety standards. Shandong Tongyi pumps are manufactured under strict adherence to API 610 (ISO 13709) protocols for petroleum services, and we hold CE certification for the European Economic Area, EAC certification for Eurasian markets, and specialized Russian 012 explosion-proof certifications for explosive gas environments.
Each pump undergoes detailed quality control checks, including material heat-treatment analysis, non-destructive testing (NDT) of pressure-retaining castings, hydrostatic pressure tests, and hydraulic performance validation. This consistent approach ensures that our OEM/ODM products meet the strict safety and performance standards of global engineering companies.
We provide engineering support from the design phase to installation and commissioning. Our technical service team works closely with engineering partners to verify Net Positive Suction Head (NPSHa/NPSHr), select suitable elastomeric compounds, and optimize impeller trims using Computational Fluid Dynamics (CFD).
Our logistics department coordinates international shipping, custom packaging, and export documentation to ensure safe, on-time delivery. We supply technical installation guides, spare parts lists, and operational documentation in multiple languages to facilitate onsite commissioning and regular maintenance.
Integrating digital monitoring and energy-efficient designs to support modern, sustainable operations.
We are integrating vibration, temperature, and pressure sensors into our pump bearing housings. Real-time data streams help plant operators monitor system status and schedule maintenance before failures occur.
By using CFD analysis and 3D sand-printing for casting molds, we refine pump internal flow passages to reduce hydraulic losses and improve energy efficiency.
Our research focuses on double cartridge mechanical seals and seal auxiliary systems that meet strict API plans. This design prevents volatile organic compound (VOC) leakage and protects the environment.
