Corrosion resistant chemical pump for alkali liquid IJ type single stage single suction cantilever chemical centrifugal pump is a new product optimized and designed based on the IH series chemical pump, referring to the latest foreign technology and combining with the actual use of users. Its rated performance and installation size comply with the ISO2858 standard, and its manufacturing technical conditions comply with the ISO5199 standard. It is mainly suitable for the transportation of slurry with a solid content less than 50% and crystal impurities in chemical processes. Compared with IH pumps, the structure of IJ chemical pumps has the following characteristics: 1 - Shortened the cantilever of the impeller and thickened the diameter of the shaft; 2 - Asymmetric cross-section volutes and pump casings without mouth rings; 3 - Three imported bearings are used; 4 - Equipped with a new type of seal similar to foreign advanced double face mechanical seals or packing seals. Due to the above structure, the pump has the following advantages: 1 - It can transport high viscosity or solid containing media, and the efficiency of the pump is higher than that of the IH chemical pump; 2 - The asymmetric cross-section volute reduces the impact loss of fluid and shortens the size of the pump casing; 3 - Increasing the strength of the shaft reduces the deflection of the rotor, resulting in stable operation and long sealing life; 4 - The impeller nut is integrated with the impeller, improving the inlet conditions of the pump and enhancing the anti cavitation performance of the pump; 5 - Advanced shaft seal form ensures better sealing effect and reduces pump leakage; 6 - The clearance of the pump can be adjusted without disassembling the pump casing and impeller, reducing maintenance time and saving maintenance costs. Applicable fields: alkali production, salt chemical industry, petrochemical industry, paper mills, pulp industry, refineries, coal chemical industry, power plants, pharmaceutical industry, sugar industry, steelmaking plant, water treatment coating industry (degreasing, phosphating, electrophoresis and other processes)

X-rings, also known as star rings due to their distinctive X-shaped cross- section, represent a thoughtful upgrade from the traditional O-ring. While both serve the purpose of sealing, the X-ring stands out for its refined design— specifically the four sealing lips and a small lubrication cavity in the center. This unique structure helps reduce both friction and starting resistance, making it ideal for dynamic applications. One of the often-overlooked advantages of X-rings is the positioning of the flash line—it sits in the recessed area of the cross-section, which not only improves the seal but also reduces the chances of leakage. In other words, the X-ring takes everything good about the O-ring and pushes it one step further. A Smarter Choice for Demanding Applications X-rings can be used in a wide variety of environments. To ensure optimal performance, the material must be chosen based on factors like temperature, pressure, and the type of medium involved. It’s not just about choosing a rubber ring—it’s about matching the right material to the job. When setting up a system, engineers should factor in peak and continuous operating temperatures, the frequency of use, and in rotating applications, the heat generated from friction. These considerations will determine the service life and effectiveness of the seal. What Makes X-Rings a Better Performer? Unlike an O-ring, which only has one contact point, the X-ring offers four contact surfaces. This means pressure is distributed more evenly, reducing friction by up to 40% and significantly slowing wear over time. It’s a clear performance boost, especially in systems that cycle frequently. Where Do X-Rings Shine? You’ll find X-rings in some of the most demanding applications: Heavy-duty machinery: hydraulic cylinders in excavators and presses Industrial robotics and turbines: rotating shafts and spindles Aerospace systems: actuators in aircraft landing gear that face sudden pressure changes Automotive transmissions: dual clutch systems that require precise sealing Oil and gas: critical components like blowout preventers in offshore rigs Material Options for Different Needs Different environments demand different materials, and X-rings are available in several: NBR (nitrile rubber): cost-effective, reliable across a wide range of industrial uses (-40°C to +125°C) FKM (fluoroelastomer): excellent resistance to high temperatures and aggressive fluids (-20°C to +250°C) PTFE: ideal for low-friction, high-precision sealing in sensitive equipment Why DEDE’s X-Rings Stand Out As a certified high-tech enterprise recognized for “specialization, refinement, and innovation,” DEDE brings over 30 years of experience in sealing technology.

Centrifugal pump with Small vacuum storage siphon tank Siphon tank/bucket, also known as vacuum tank /bucket or water diversion tank, utilizes the principle that the vacuum of a sealed container can generate suction force. When used in conjunction with a regular centrifugal pump, it can produce a self- suction effect (equivalent to a self-suction pump), with a larger self-suction height of about 4m. Its advantages are easy assembly, easy maintenance of a single pump, stable self- priming performance, and more cost-effective than self-priming pumps; The disadvantage is that it occupies a large area. Why choose a siphon tank/ bucket? self-suction/priming pump has a complex pump body structure, relatively high production and installation costs, and a higher overall pump price; The combination of a siphon tank/bucket and a regular centrifugal pump can also achieve the effect of a self-priming pump, but the cost of the individual unit is relatively low, and the maintenance of the pump body is also convenient. If the pump is damaged, only the pump needs to be replaced, and the siphon bucket can continue to be used. In the one in use and one backup working condition, only the continuous siphon bucket can be used, saving procurement costs. Submerged pump is a conventional corrosion-resistant engineering plastic submerged pump. Due to manufacturing process limitations, its submerged depth does not exceed 2m (the submerged pump is too long, unstable to operate, and has a short service life). It is not suitable for use in deep pool conditions; The self-suction height of the siphon tank /bucket and ordinary centrifugal pump can reach 4m, with a wider application range.
