SPE, a mechanical seal design and manufacturing company, has launched a slurry seal series of separable gland cartridge seals. These seals support the slurry, fiber, rubber, crystallising and high viscosity processes in petrochemical, pharmaceutical, pulp and paper, bio-diesel, mining, and wastewater treatment industries. 

SPE’s Chief Operating Officer, Yi-Chieh Huang, drove this design idea. Huang combines mechanical engineering expertise and an MBA degree from MIT Sloan with over 14 years of extensive experience in the machinery manufacturing and sealing technology of rotating equipment fields. 

Huang led an R&D team to accelerate product incubation, from product road mapping, design, prototype remodel, dynamic testing to dimension standardisation, until it was launched in several market segments. The slurry seal products have six patents with three types of novel structure cartridge seals.

A first-of-its-kind sealing technology

The slurry seal products include a separable gland with an exchangeable internal cartridge seal that is compatible with each of the three seal types. This significant innovation is a first-of-its-kind application in the sealing technology field. 

Maintenance personnel can rotate the gland to align with fixed bolts when installing a cartridge seal, saving time during the installation process. 

This design reduces the seal’s replacement cost using an economical metallic material without the gland contacting process media. The internal cartridge seal with its high-quality solid material has excellent chemical corrosion resistance characteristics and an effective clog-resistant structure. As a result, the seal’s mean-time-between-failure (MTBF) is extended by at least 30 per cent and reduces maintenance procedure time.

Designed for reliability

Moreover, Huang led the team to overcome several technical bottlenecks for enhancing seal advantages and reliability. 

One example is designing the slurry seal series to handle short dry-running applications during unforeseen operating issues. The seal structure can automatically align a +/- 0.5mm shaft misalignment and compensate for shaft runout. Consequently, the upgraded seal face material and the excellent structure eliminate the need for a complex piping connection, thus saving water from an external flush. 

Huang’s team successfully introduced the slurry seals for slurry pumps and reactive mixers to improve equipment performance.

Huang’s track record of developing high-performance seal products includes advanced composites for upgraded product applications. The achievements Huang implemented include lowering rotating equipment energy consumption in response to government policies and industrial trends. 

Applying these solutions, Huang led cross-functional teams to complete many plant expansion projects involving equipment manufacturing and plant engineering, where her outstanding technical solutions aligned with customised requirements. 

“Our mission is continually providing comprehensive technical solutions for our clients to meet their needs. We like working on our customer’s challenging technical issues because I believe they inspire us towards more innovations in this sector,” Huang said.  

Huang contributes her expertise with business operations, technology commercialisation, organisational innovation and marketing strategy to advance SPE’s mission of providing clients with advanced products with multiple-functionalities and industrial fluid mechanics solutions.
