To address these core industry pain points, FBU Sealing Technology (Suzhou) Co., Ltd. has developed a full-chain one-stop sealing solution based on its profound experience in mechanical seal R&D and application. This solution breaks down industry barriers of multi-party coordination, realizes reasonable matching of mechanical seals, auxiliary systems, and paper-specific working conditions, and provides paper customers with a full-cycle closed-loop service from selection and design, product manufacturing to installation and maintenance.
| Core Advantages | Detailed Description |
| One-Stop Full-Process Service | Integrates the full-chain capabilities of seal R&D, auxiliary system customization, and paper working condition adaptation. Customers do not need to connect with multiple suppliers; a single interface completes the implementation of full-system requirements, greatly reducing communication costs, eliminating demand transmission deviations, and ensuring the adaptability of sealing systems to on-site paper production conditions from the source. |
| Native Design for Data Interconnection | Different from the traditional "select seal first, match system later" assembly model, the solution adopts a native collaborative design concept. It fully matches key data including pulp fiber characteristics, medium corrosiveness, operating heat generation, and working condition fluctuation boundaries with the cooling capacity, circulation flow, and pressure control accuracy of auxiliary systems, realizing data sharing. This helps mechanical seals and auxiliary systems maintain stable performance across full working conditions and effectively reduces equipment failures and production interruptions caused by selection mismatches. |
| Performance Optimization for Full Working Conditions | Combined with the core characteristics of continuous production and high fiber abrasion in the paper industry, reasonable selection and system collaboration optimize the operating status of seal faces, reduce the impact of fiber abrasion and medium corrosion, improve equipment operation stability, cut down unplanned shutdowns and maintenance costs, lower seal heat generation and energy consumption, and create long-term stable operating value and quality assurance for paper enterprises. |
The core strengths of FBU’s one-stop sealing solution have been fully validated in various working conditions of the paper industry. The collaborative combination of the 2233 Series Mechanical Seal and LB541 Barrier Fluid Supply System has become a replicable benchmark application for industry customers. The core features and adaptability of the two products for paper industry conditions are shown in the table below:
| Product Name | Core Design / Functions | Applicable Scenarios & Adaptation Parameters for Paper Industry |
| 2233 Series Mechanical Seal | Adopts stationary compensating seal face and balanced structure with multiple spring compensation, ensuring uniform force distribution on the seal ring face. It effectively reduces face wear and operating heat generation caused by pulp fibers, optimizes pump efficiency, and adapts to multi-medium and fluctuating working conditions in the paper industry. | Suitable for core equipment such as pulp pumps in pulp making, circulation pumps in paper forming, and chemical delivery pumps; compatible with API Plan 01, 02, 11, 12, 13, 21, 22 and other common flushing plans in the paper industry; shaft diameters cover 33mm to 115mm; dimensionally adapted to mainstream pump models in the paper industry including Andritz ACP pumps to meet equipment matching needs of paper production lines of different scales. |
| LB541 Barrier Fluid Supply System | A high-performance liquid circulation unit that continuously supplies cooled barrier fluid to multiple independent sealing auxiliary systems; supports intermittent operation to reduce on-site energy consumption for paper enterprises; optional pressure switches and accumulators enable refined control of water/oil circulation pressure. | Suitable for cooling and pressure control of sealing auxiliary systems in pulp making, paper forming, chemical delivery and other links of the paper industry; operation is unaffected by equipment working condition fluctuations and operating pressure differences, ensuring stable performance of water control systems and providing a suitable operating environment for seal faces to meet the continuous production needs of paper lines. |
Different from simple product combination in the industry, the FBU 2233 Series Mechanical Seal and LB541 Barrier Fluid Supply System achieve full-parameter matching at the design stage, realizing deep interconnection between sealing operation data and system control logic under paper industry conditions. The pulp abrasion resistance, operating heat generation, pressure limits, and pump efficiency of the 2233 Series are natively matched with the cooling capacity, pressure control accuracy, and circulation flow of the LB541 System. No multi-party coordination or secondary adaptation is required, solving the sealing and auxiliary system selection and matching challenges for the paper industry in a one-stop manner.
