We offer professional solutions for all industrial processes of sulfuric acid and its production. Our vertical pumps are made of corrosion-resistant materials to safety convey sulfuric acid at high temperatures. Providing maximum resistance to corrosion and to high temperatures, YOUNAI vertical pumps have numerous references and experiences.


Tailored Pumping Solutions for H2SO₄
YOUNAI is able to draw on many years of experience with PTFE, PFA, nickel-chromium alloy, stainless steel and ceramic materials that are corrosion resistant and high-temperature resistant.
Taking into account the special requirements of the pumped medium, we select the appropriate vertical sulfuric acid pump model, choose the right material, and develop a tailored solution to make sure pumping successfully. For many years, we have been a trusted partner in the field of sulfuric acid processing.
Vertical Pumps , Extremely High-Temperature , Molten Salt


Due to their optimized design and excellent materials, YOUNAI vertical molten salt pumps ensure the maximum reliability and durability. They deliver outstanding operational performance, proven through longer continuous operation, smooth running, and lower noise, even under extreme conditions (Max flow: 1600m³/h; Max temperature: 850℃).
YOUNAI is committed to support the development of renewable and clean energy. We offer a wide range of vertical molten salt pumps and related services for concentrated solar power (CSP) plants.
Vertical Pumps for Large Flows
Designed for large flows at low head applications. Excellent hydraulics and precise manufacturing enable YOUNAI vertical pumps to deliver superior performance, high efficiency, smooth operation, and maximum reliability. Ideal for municipal water supply, drainage, flood control, power plants, and industrial processes.





YOUNAI: Vertical Pump Manufacturing
YOUNAI is committed to data-driven innovative design, improvement, and upgrades, with every vertical pump tested before delivery. Our professional vertical pump test platform—including the test control room, very deep water pools, and large-scale crane systems—are operated by the testing staff. Customers can have full confidence in our pump performance, as it is validated by measurable performance metrics including flow rates, heads, efficiency, speed, power consumption , vibration, noise levels, temperature rising, etc.
The high reliability of YOUNAI vertical pumps benefits from advanced manufacturing techniques, including precision casting, machining, and quality-controlled assembly processes. Efficiency gains are realized by hydraulically optimizing the hydraulic components, including impellers, guide vanes, and volute casing. Customized vertical pumps are engineered to handle demanding requirements such as large flows, corrosion, abrasion, high temperatures, and other challenging conditions.

- Regarding vertical pumps, we have deep industry expertise. After receivingcustomer parameters, our sales and engineering teams can quickly recommendthe correct model and material selection, providing performance curves, installation drawings, and relevant reference cases.
- We maintain a wide range of semi-finished parts in stock.
- Highly efficient manufacturing workflows and modern facility management ensure high productivity.
To handle corrosive medium, special materials including stainless steel, duplex stainless steel, super duplex stainless steel,titanium alloy, nickel, Monel, and hastelloy can be used. The vertical pump casing is designed to for a pressure of 16 bar. The discharge flange dimensions comply with DIN and ASME standards. On request pressure ratings above 16 bar, or high-temperature resistant, YOUNAI can also be supplied.
YOUNAI’s vertical molten salt pumps are an upgraded molten salt pump design with a broader application range.
They can convey:
High-temperature nitrates and nitrites
Various high-temperature chemical materials including:
Membrane-process solid alkali
Binary/ternary molten salts for organic fluoride cracking
Phosphate fertilizers
Petroleum cracking fluids
Operating temperatures up to 850℃ are supported.
Advantages of YOUNAI Vertical Sulfuric Acid Pumps
The vertical sulfuric acid pump adopts the structure of a vertical single-stage single-suction submerged centrifugal pump design. Featuring an advanced design, an efficient hydraulics, and easy installation and maintenance. The upper shaft is supported by a double bearing frame, while the lower part is supported by a sliding bearing bushes and sleeves for stability. This superior construction enables smooth operation, low noise, minimal vibration, high efficiency, and long service life.
Moreover, for handling 93–98% concentrated sulfuric acid, YOUNAI has developed fuming acid pumps that effectively prevent SO₃ gas escape. Our high-temperature sulfuric acid pumps withstand extreme temperatures of 190–220°C. A cooling water circulation system around the bearing housing allows extended continuous operation and significantly enhances durability.
Transporting vertical pumps—especially large vertical axial flow pumps, large vertical mixed flow pumps, long-shaft submerged pumps, or molten salt pumps—involves challenges in transportation and installation. Fortunately, YOUNAI has extensive experience in this area. There are usually two options: bulk sea freight for oversized units, or containerized shipment after disassembly, followed by on-site reassembly guided by our engineers. The final approach is always tailored to your specific project requirements or customer’s needs.
As a leading manufacturer of high-quality, full-range vertical pumps, YOUNAI deeply understands that the process from project initiation to the successful operation of large vertical pumps is a complex one, requiring coordination and collaboration among multiple departments. With extensive experience in the production and successful application of large vertical pumps, YOUNAI provides end-to-end technical support for global customers throughout procurement, installation, and operation.
For the vertical pump pre-installation stage—including well inspection and development, building the foundation, unloading parts, and preparing the parts for installation— we offer detailed, cost-effective remote technical support.
For critical on-site processes including installing the bowl unit, column, and discharge head; aligning the pump; tensioning the enclosed tube; installing the motor; grounding the discharge head; installing the discharge piping; setting up the lubrication system; adjusting impellers; and initial start-up, our engineers will be present at your site to provide direct guidance to ensure the successful installation and reliable operation of your large-scale vertical pumps.
Vertical mixed flow pumps feature high flow rates, moderate head, and vertical installation, making them suitable for a wide range of applications. YOUNAI matches the materials for its vertical mixed flow pumps to the specific operating condition. For applications such as agricultural irrigation, municipal drainage, and flood control, vertical pumps would be made from cast iron, carbon steel, or chrome steel. In seawater desalination and marine applications, stainless steel is essential. For the demanding applications of the chemical, petrochemical, and thermal power generation, vertical mixed flow pumps are made from specialized materials, such as stainless steel, duplex stainless steel, titanium, nickel alloys, offering superior corrosion or high-temperature resistance.
