On-Demand Spare Parts for Vertical Turbine Pumps: A Case Study in Industrial Additive Manufacturing

17 Nov 2025

Timely sourcing of spare parts is a critical challenge for industrial equipment service providers, particularly when rapid turnaround on low-volume components is essential to maintain plant operations in the water treatment and energy sector. Sulzer is advancing its on-demand parts strategy by leveraging additive manufacturing in its aftermarket service business. Sulzer partnered with 3D Systems to develop digital manufacturing workflows addressing urgent spare parts needs in a highly demanding industrial context.

By incorporating laser powder bed fusion (LPBF) technology into its manufacturing workflow, Sulzer has achieved fast track, flexible production of key pump components through process and supply chain optimization. The new workflow demonstrates significant lead time reduction and operational security for customers, with broader business impact for Sulzer.

During this session, Dr. Yogi Pardhi, Global Lead for Additive Manufacturing, for Sulzer Services will be joined by Dr. Pierre Van Cauwenbergh, Senior Application Engineer, 3D Systems to detail the collaborative development and deployment of an end-to-end additive manufacturing solution for vertical turbine pump spare parts. The case study covers the end-to-end manufacturing workflow of large pump impellers and housings from advanced file preparation to post-processing. 3D Systems partnered with Wilting and Kusters, both part of Andra Tech Group, to develop advanced post-processing capabilities for large pump impellers and housings, ensuring compliance with industry standards and improving overall manufacturing efficiency.
