Over the past few years, the way major pump manufacturers select their suppliers has changed significantly. Product quality remains essential, but it is now assessed alongside a broader set of criteria, including material traceability, strong manufacturing processes, technical documentation, certifications, and the ability to meet increasingly demanding environmental, social and governance (ESG) requirements.
For companies supplying pump manufacturers, this shift has practical implications: a level regulator or an inverter is no longer judged on technical performance alone. What also counts is how the component is manufactured, the quality controls applied throughout the production process, and the availability of clear, reliable documentation for customers, particularly when the component is integrated into complex systems or supplied to highly regulated markets.
For companies like Mac3, which have been working alongside pump manufacturers and distributors for more than forty years, sustainability cannot remain an abstract claim, detached from the product. It must become an integral part of the overall quality of supply.
Measuring, tracking and documenting
As transparency becomes increasingly important across the industry, claiming to operate responsibly is no longer enough.
Companies that have invested in well-structured processes are better equipped to respond to these new expectations. At Mac3, Lean Production principles, combined with comprehensive traceability and quality control systems, provide greater visibility into manufacturing processes, materials, and every stage of production.
For OEMs and pump manufacturers, this is no longer a formality. It means working with a supplier that delivers not only a compliant product, but also the information needed to qualify the supply, respond to internal stakeholders, and reduce risk throughout the supply chain.
Certifications such as ISO 9001, together with product-specific certifications, help make this commitment measurable and verifiable. While certifications alone do not tell the whole story of a company’s value, they provide objective evidence of the quality embedded in everyday operations, making it easier for customers to assess, integrate and certify their own supply chains.
As Eng. Enrico Pilotto of DAB Pumps pointed out during our Building Value Together event: “Customers increasingly need sustainability guarantees from their suppliers. In public tenders, an integrated and transparent approach to sustainability has become a prerequisite.”
This reflects a broader transformation affecting the entire water industry supply chain. Sustainability is becoming an integral part of supplier qualification, technical specifications, tender requirements and risk assessments. To support this shift, companies need clear processes, traceable materials, documented quality controls and reliable information.
Sustainability starts with the product
Improving internal processes is only one part of the journey. The other part concerns the product: how it is designed, which materials it uses, and how effectively it meets both customer requirements and the market expectations.
This is the case with Key Green, the MAC3 level regulator made from recycled polypropylene. For customers, the decisive point is consistency of performance and reliability in real operating conditions. Using recycled materials only creates value if the component continues to guarantee accurate switching, mechanical strength, electrical safety and long-term durability.
For pump manufacturers, this means being able to add a component to their range that is better aligned with sustainability requirements, without changing installation procedures, selection criteria or operating standards.
EU Drinking Water Directive: raising the standard for materials
The focus on transparency becomes even more relevant when looking at how European legislation on the quality of water intended for human consumption is evolving.
The Drinking Water Directive (EU 2020/2184), which will apply from 31 December 2026, introduces a more harmonised framework for drinking water quality across Europe and establishes specific requirements for materials that come into contact with drinking water.
These changes affect the entire supply chain. Pump manufacturers, OEMs and distributors need to be able to rely on well-prepared suppliers that can provide technical documentation, recognised certifications and approved materials suitable for drinking water applications.
Within this context, certifications such as ACS for drinking water applications become valuable tools for reducing uncertainty and simplifying component qualification. They are more than a formal requirement: they help designers, manufacturers and distributors quickly verify whether a component complies with market expectations and regulatory requirements.
Looking ahead, together
Regulatory, environmental and manufacturing challenges cannot be addressed in isolation. They require stronger collaboration across the supply chain, shared standards, and closer cooperation between designers, manufacturers, distributors and installers.
A more sustainable supply chain is built on clear processes, reliable products and trusted partnerships. It means knowing who manufactures every component, understanding how it is produced, what quality controls are in place, and how the supplier can support customers as market conditions and regulations continue to evolve.
For companies responsible for ensuring operational continuity, system safety and product compliance, this level of reliability delivers tangible value: it reduces risk, simplifies decision-making and strengthens the resilience and quality of the entire supply chain.
Frequently Asked Questions
What role do product certifications play in the water industry supply chain?
Product certifications provide objective evidence that manufacturing processes and products meet recognised quality and compliance standards. For OEMs, distributors and pump manufacturers, they are an important tool for qualifying suppliers, reducing risk and streamlining technical documentation.
Does the Drinking Water Directive also apply to components used in pumping systems?
The Directive’s requirements for materials in contact with drinking water extend throughout the supply chain, not just to the finished product. This makes it increasingly important to work with suppliers that can provide recognised certifications, technical documentation and approved materials for drinking water applications.
