As a core fluid transfer equipment under Sulzer Group, the Sulzer®SNS pump is widely used in various fluid transfer scenarios in the papermaking industry, thanks to its excellent quality and stable performance, serving as one of the core equipment to ensure continuous and efficient production. Sulzer Pumps has deep roots in the global industrial sector, boasting a comprehensive product system and mature service network in the papermaking industry. The Sulzer®SNS pumps it produces have passed strict quality certifications, balancing high-efficiency transfer and durability to meet the medium transfer needs of different sections in papermaking production, earning the trust and recognition of numerous papermaking enterprises worldwide. The adaptability and quality of sealing components directly determine the performance of the pumps.
Sealing components are the core accessories for Sulzer®SNS pumps to prevent leakage and ensure stability. Their adaptability and quality are directly related to pump operating efficiency, service life, as well as production continuity and production costs. Developed specifically for the papermaking industry, the SNSS and SNSD series seals are designed to match the structural characteristics of this pump series and the operating conditions of the papermaking industry. Fully complying with Sulzer pump adaptation standards, these seals feature high-quality materials and adaptive structural design, which can well fit the Sulzer®SNS pump chamber and build a solid sealing barrier for equipment operation.
The SNSS series seals adopt a wave spring compensation structure, providing stable spring compensation performance. They can fit well with the Sulzer SNS pump cover, matching the pump chamber installation dimensions and operating conditions. As special seals for the papermaking industry, this series is suitable for general operating conditions in papermaking production, compatible with various sealing plans including Plan 01, 02, 11, 12, 13, 21, and 22, covering different fluid transfer scenarios. With shaft diameter specifications including 30, 40, 50, 60 and other common sizes, it can adapt to various common models of Sulzer®SNS pumps, allowing direct installation and use without additional modifications, thus reducing installation complexity and adaptation risks.
The SNSD series seals also adopt a wave spring compensation structure, offering the same stable compensation capability and reliable sealing performance as the SNSS series. They can well match the Sulzer SNS pump cover structure and smoothly adapt to pump chamber operation. Complementary to the SNSS series, this series is mainly compatible with sealing plans such as Plan 52, 53A, and 54, providing reliable sealing solutions for different medium characteristics and sealing protection needs in papermaking production. It also covers common shaft diameter specifications of 30, 40, 50, 60 and others, which can flexibly adapt to Sulzer®SNS pumps, ensuring that the pump chamber sealing performance meets the standard. It alleviates the impact of vibration and axial displacement on the seal during pump operation, reduces leakage risks, and meets the high reliability requirements of continuous papermaking production.
Addressing the pain points of operating conditions in the papermaking industry, the SNSS and SNSD series seals fully consider the medium characteristics of papermaking production and the operating environment of the pump body during R&D and production. High-quality adaptive materials are selected to balance wear resistance, corrosion resistance and stability, which can effectively cope with various operating challenges, extend the service life of the seals, reduce replacement frequency and maintenance costs, and lower production losses. Both series have passed strict quality inspections, meeting industrial use standards and matching the quality of Sulzer®SNS pumps, helping the equipment operate continuously and efficiently, and avoiding production interruptions, medium leakage and other problems caused by seal failure.
Equipping with suitable sealing accessories is the key to ensuring the stable operation of Sulzer®SNS pumps. With exclusive adaptive design, stable and reliable quality, and a variety of adaptive solutions, the SNSS and SNSD series seals can well meet the usage needs of this pump series, escorting papermaking production, helping each Sulzer®SNS pump give full play to its performance advantages, and ensuring efficient and orderly production.
