Wilo – Overview
Wilo is a multinational pump manufacturer headquartered in Dortmund, Germany, with U.S. operations based in Cedarburg, Wisconsin. One of the world’s leading premium suppliers of pumps and pump systems, Wilo serves building services, water management, and industrial applications across more than 60 countries with a global workforce of over 8,400 people.
What sets Wilo apart is their commitment to intelligent, energy-efficient design. Where many manufacturers still build pumps as purely mechanical products, Wilo has spent decades developing the controls, connectivity, and software that surround the pump itself. The result is equipment that does not just move water — it monitors itself, communicates with building systems, adapts to changing demand, and flags problems before they become failures. That shift from mechanical product to intelligent system is not a marketing position for Wilo. It is the direction their engineering has been moving since they introduced the world’s first fully electronic pump in 1988.
Today that thinking shows up across their product line in the form of variable speed drives that reduce energy consumption by matching motor output to actual system demand, integrated PLCs that manage multi-pump booster systems without external controllers, and the Wilo-Assistant app that gives technicians and facilities managers remote visibility into pump performance from a mobile device. For engineers specifying commercial plumbing and HVAC systems, Wilo also provides a suite of digital tools — including pump selection software, system dimensioning calculators, and custom catalog creation — designed to support the specification process from the earliest stages of a project.
Their solutions span circulator pumps, inline pumps, end suction pumps, split case pumps, booster systems, submersible pumps, vertical turbine pumps, and prefabricated hydraulic modules. Across all of it, the throughline is the same: equipment built to perform efficiently, communicate clearly, and hold up in demanding commercial and industrial environments.

WHY MERION PUMP AND WILO
Merion Pump has built its reputation over decades by putting the right equipment in the right application and standing behind it. Adding Wilo to our line card was a deliberate decision, not a default one.
For engineers specifying commercial plumbing and HVAC systems, the selection process matters as much as the product itself. Wilo understands that. Their engineering tools, including pump selection software, system dimensioning tools, and custom catalog creation, are built to support the specifying process from the start, not just after a purchase order is written. That kind of manufacturer support makes our job easier and makes your specifications more defensible.
The Wilo product line covers the full range of what commercial plumbing and HVAC systems demand, from circulators and inline pumps to booster systems and prefabricated hydraulic modules. When a project calls for a pump solution, we can have that conversation across a wide range of applications without sending you somewhere else.
We are still growing our familiarity with the full depth of what Wilo offers, and that is intentional. We would rather know the line well than sell it broadly. If you have a project in front of you and want to talk through whether Wilo is the right fit, that is exactly the conversation we are here to have.
FEATURED PRODUCTS
Wilo-CO MVI
When a commercial building needs consistent water pressure across multiple floors or zones, the Wilo-CO MVI delivers. This pressure boosting package uses variable speed control and intelligent controls to maintain steady system pressure without the energy waste of running at full capacity around the clock. A strong fit for mid to large commercial plumbing applications.
Wilo-WiBooster
A compact, pre-engineered booster system designed for installations where space is limited but performance cannot be compromised. The WiBooster arrives ready to connect, reducing installation time and the variables that come with field-assembled systems. Well suited for light commercial and plumbing applications.
Wilo-Helix EXCEL Complete
Built for demanding commercial and industrial pressure boosting applications, the Helix EXCEL Complete combines high-efficiency pump technology with an integrated control system and remote monitoring capability. Facilities managers and engineers who need reliable pressure maintenance with real-time diagnostics will find this system worth specifying.
