Overview
The Integrated Pneumatic Module (IPM) was developed to provide a standardized pneumatic interface for Flowserve's rack-and-pinion pneumatic actuators in accordance with the VDI/VDE 3847-2 standard. By integrating the pneumatic air distribution within the module, the design eliminates external tubing and enables plug-and-play replacement of pneumatic accessories, significantly simplifying maintenance and reducing downtime.
The project was initiated to meet a new requirement from BASF, one of Flowserve's key customers, where delivering a compliant solution within a demanding timeframe was critical. As Flowserve had never developed an IPM before, the project required the creation of an entirely new product platform while complying with a newly adopted industry standard.
Project Development
The project was led by Flowserve's engineering team in the United Kingdom, who were responsible for the overall product development. Due to limited engineering capacity, I was asked to support the project by taking ownership of the mechanical design of the IPM.
Understanding the Requirements
My first responsibility was to study and interpret the requirements of the VDI/VDE 3847-2 standard before benchmarking existing solutions available on the market. This provided a clear understanding of the functional requirements and helped identify different design approaches already adopted within the industry. Based on this research, I developed Flowserve's first IPM concept from scratch.
Concept Development
One of the biggest engineering challenges was designing a solution that could accommodate the company's entire range of pneumatic actuators while working within very limited packaging constraints. During the concept phase, it became clear that a single module could not efficiently cover every actuator size. Together with the engineering team in the United Kingdom, we decided to develop two module variants, allowing the design to remain compact while covering the complete product range.
Detailed Design & Prototype Validation
I was responsible for creating the complete CAD assembly, including the internal pneumatic air passages, sealing interfaces, and mounting features required for the modular accessory system. After completing the design, I produced the manufacturing drawings used for prototype production. The prototype components were machined from aluminium at one of Flowserve's manufacturing sites in China before being assembled and tested as part of the validation process.
Outcome
The project resulted in Flowserve's first Integrated Pneumatic Module compliant with the VDI/VDE 3847-2 standard, providing a standardized and service-friendly pneumatic interface for the company's rack & pinion actuator platform. The successful prototype demonstrated the technical feasibility of the design while fulfilling an important customer requirement. To the best of my knowledge, the product was not commercially released following completion of the development.
In recognition of my contribution to the project, I received an internal Project Award, acknowledging my role in delivering the project within a challenging timeframe.
