Underpinned by the founding philosophy of "science and technology leading, quality oriented, and reputation first", we have established ourselves at the vanguard of innovation and engineering excellence.
Our dedicated commitment to research and development has enabled us to achieve pioneering breakthroughs in mechanical structure design, thermal-dynamic efficiency, and anti-corrosive metallurgic formulations, allowing us to supply high-reliability pump solutions for complex process plants globally.
Initiated dedicated production of water ring and reciprocating vacuum pumps, laying down a strong engineering foundation in Shandong.
Expanded engineering portfolio to heavy-duty horizontal slurry pumps and high-pressure chemical metering units to serve process plants.
Adapted production lines to conform with ISO standards, API610 petrochemical process compliance, and UKCA safety directives.
Our production plant boasts a modern standard workshop, designed specifically for clean-room assembly, high-precision machining, and structural integrity analysis. We possess a complete, scientific quality management system certified under international protocols. Our factory floors are equipped with high-performance manufacturing technologies including:
A systematic technical roadmap for procurement managers sourcing critical industrial vacuum and pump systems.
Accurate validation of NPSHa (Available) against NPSHr (Required) is vital. Our engineering team assists buyers in sizing intake manifolds to eliminate cavitation risks in vertical multi-stage setups.
For chemical and dosing operations, fluid-contact parts require precise metallurgy. We supply AISI 304, 316, 316L, duplex steels, PTFE, PVDF, and Hastelloy to resist aggressive chemical corrosion.
Global entry requires strict compliance. Our industrial pumps conform to ISO, CE, UKCA, and API 610 directives, facilitating seamless integration into heavy-industry facilities.
An authoritative analysis of technical changes reshaping fluid mechanics and pressure control systems.
In industries such as CNC routing, woodworking, pharmaceuticals, and semiconductor packaging, hydrocarbon contamination is a critical risk. Modern engineering is shifting decisively toward dry-running technology. Dry rotary vane systems, like the Wordfik VD250, replace oil lubricants with carbon composite self-lubricating vanes. This completely eliminates oil-mist exhaust, drastically reduces maintenance intervals, and maintains stable deep vacuum pull-downs across continuous operation cycles.
Industrial operations are increasingly deploying IoT-enabled vibration, temperature, and cavitation sensors directly on pump housings. By monitoring rotor eccentricity, bearing temperature spikes, and pressure wave fluctuations in real-time, operators can predict pump seal degradation and rotor imbalances before catastrophic failures occur. This data integration decreases unplanned downtime by up to 35% in large process facilities.
With global industrial operations targeting carbon neutrality, energy efficiency in pumping applications has become paramount. Advanced Computational Fluid Dynamics (CFD) simulation allows for the design of impellers with optimal blade geometry, minimizing fluid shear stress and turbulence. Utilizing vertical multistage designs (like our Lowara-Pedrollo equivalent booster series) allows plants to adjust operating frequencies to match system demand, cutting energy usage by 20% to 40% compared to traditional single-stage throttle control valves.
Shandong Tongyi's strategic engineering plans for high-pressure and vacuum pump systems.
We are expanding our IH chemical pump lines to include hermetically sealed magnetic drive couplings. By removing traditional mechanical shaft seals, we completely eliminate leak pathways for hazardous or volatile chemicals.
Our upcoming product lines will feature integrated variable speed controllers with automated diagnostic modules, permitting automatic shutoffs upon detecting dry-run scenarios or high discharge pressures.
By using metal 3D printing techniques for prototypes, our engineering department designs impellers with complex internal flow pathways, improving efficiency and reducing cavitation wear.

At Shandong Tongyi, we maintain a robust pre-sales engineering reception, sales production tracking, and dedicated after-sales troubleshooting team. We understand that pump failure can halt an entire plant's production. Our technical engineers are available for virtual commissioning, sizing calculations, alignment checks, and maintenance training.
We work closely with logistics partners to ensure that all pump orders, spare impellers, mechanical seals, and maintenance kits are delivered on time, complete with CE, ISO, and UKCA compliance certificates.
Our senior engineering specialists provide clear answers to common questions about industrial pump installation, operation, and maintenance.
To prevent cavitation, the Net Positive Suction Head Available (NPSHa) must exceed the Net Positive Suction Head Required (NPSHr) by a safety margin, typically at least 0.5 meters. Calculate NPSHa = Ha ± Hs - Hf - Hvp, where Ha is the atmospheric pressure on the liquid surface, Hs is the static suction lift or head, Hf is the friction losses in the suction piping, and Hvp is the vapor pressure of the liquid at its operating temperature.
Oil-free dry rotary vane vacuum pumps, like the Wordfik VD250, eliminate the risk of oil mist exhausting into the workspace and oil back-streaming into wood materials. They utilize self-lubricating carbon vanes, which drastically reduce maintenance downtime, keep the working environment clean, and provide consistent suction hold-down force for woodworking router tables.
API 610 covers the minimum requirements for centrifugal pumps used in petroleum, petrochemical, and gas industry services. It dictates rigid casting designs, heavy-duty shafts, specific bearing arrangements, and pressure-retaining casings. This ensures the pump can withstand high temperatures, high pressures, and thermal shock, dramatically lowering mechanical failure rates in volatile fluid transfer.
For handling aggressive acids, materials like fluoroplastics (FSB series), PVDF, or specialized nickel alloys like Hastelloy are required. Stainless steel (316L) is suitable for mild acids, but at elevated temperatures or concentrations, engineering polymers or non-metallic lined pumps are needed to prevent corrosion and leakage.
Water ring vacuum pumps require a continuous supply of clean seal liquid (usually water) to create the liquid ring inside the casing, requiring regular monitoring of water quality, temperature, and consumption. Dry rotary vane pumps require no seal fluid, but require periodic inspection and replacement of the self-lubricating carbon vanes as they wear down over time.
