Brand

Wilo

As a global player, Wilo is always striving to place the requirements of the customers at the heart of what it does and to find tailor-made solutions for our customers and partner companies. Making. Life. Easy. We use this triumvirate as a basis for developing products and solutions which make people's lives more comfortable in many ways. FROM LOCAL SPECIALIST TO GLOBAL PLAYER Founded in 1872 as Kupfer- und Messing ware Fabrik in Dortmund, Wilo has evolved from being a local specialist to a global player. As the majority shareholder with a stake of approximately 90 percent, the Caspar Ludwig Opländer Foundation ensures the company's continuity and independence. An uncompromising customer-driven mindset, immediate market proximity and, in particular, our culture of innovation have made us who we are; one of the worldwide leading manufacturers of high-tech pumps and pump systems. CUSTOMER REQUIREMENTS AS OUR AIM Wilo always strives to solve problems that have been identified and exceed the customers’ requirements. A high standard, which provides a benchmark for us that we like to be measured by. We examine customer requirements early and from an all-round perspective. Successful inventions are developed at Wilo using our sound knowledge and reliable sense for future technological and market requirements. When both converge, product benefits reach a new level of quality. Intelligence. Inspiration. Innovation spirit. As a pioneer in the pump industry, we focus on anything that moves water. We have the most important prerequisites for continuously setting new standards with Wilo developments, products, systems and services: This includes our international team, comprising experienced and creative employees and cutting-edge technical facilities. WHAT WILO DOES Wilo is a premium supplier for the building services, water management and industrial sectors. Our leading position drives us to maintain our superiority. We make complex technologies user-friendly, simple to operate, energy-efficient and powerful for our customers. In the end, the main focus of everything we do is people.

THE WILO SEGMENTS We apply our values and drive to all of our segments. This means we can guarantee quality and sustainability. WILO BUILDING SERVICES In building services, we offer high-tech pumps and pump systems for both residential houses and commercial facilities. Multi-family houses are supplied reliably and environmentally-friendly by Wilo pumps. WATER MANAGEMENT Water management in the areas of water supply as well as drainage and sewage is the segment in which we have a particularly extensive amount of know-how and many years of expertise. All Wilo pumps and systems in your segment are in a highly technological state and specialised, to fulfil specific requirements. WILO INDUSTRY The supply of industrial enterprises is a very extensive and economically complex segment with highly specialised pump systems. Wilo proved itself in this area decades ago and has remained true to its principles by constantly adhering to all of its high quality requirements. WILO OEM In the OEM segment, Wilo offers a high-efficiency and cost-conscious product portfolio in addition to tailored services. Here, products in the sectors of cooling, heating, solar thermal energy, geothermal energy and sanitation are being constantly adapted to customer wishes and requirements. In all of the segments we are active in, new and powerful pump systems are constantly being further developed and optimised by Wilo engineers, in order to meet the permanently growing and more complex requirements. DORTMUND AS A LOCATION AS A MATTER OF CONVICTION Dortmund has established itself as Wilo’s headquarters. Besides the marketing investments in Borussia Dortmund, Wilo is also now investing significantly in Dortmund as a location. Here, where our success story started the Wilo Campus is now being built – currently Germany’s largest industrial building project. However, it is not an emotional or ideal driving this, it is a tough business decision. The argument for Dortmund is the market proximity to all of the production sites in Europe, the good infrastructure and the availability of well trained staff, so that the site is undisputed as a choice of location given its existing expertise.
