Firefighting

Reliable, customised solutions for firefighting water supply

Fires strike without warning. In an emergency, every detail must work as intended. Whether in a hospital, data centre, industrial facility, or airport: wherever people, property and critical infrastructure need to be protected, a reliable supply of firefighting water is essential.

At the same time, complex standards, individual project requirements and tight schedules place high demands on the planning process. System failures or reliability issues can have serious safety and financial consequences, including increased insurance requirements, building closures or even the fire service being called to tackle a blaze.

At Wilo, our teams of experts develop the right solution for every project—technically precise, compliant with standards, and precisely tailored to the requirements of your firefighting system. We offer comprehensive, flexibly configurable solutions and support you from the planning stage through to long-term, reliable operation.

Requirements for firefighting systems

Modern systems must meet a wide range of technical and organisational requirements:

  • Availability and compliance with strict international and local standards
  • Requirements depending on the building, application and market
  • Compact, modularly configurable systems for limited space
  • Clearly defined inspection and testing requirements

The most suitable solution depends on the interplay of applicable standards, project-specific certification requirements and the respective fire protection plan.

Safety begins long before an emergency occurs

Every project has its own specific requirements for firefighting water supply. A building's usage, its fire protection plan, applicable standards and certifications, as well as structural conditions, all influence the system’s design. At the same time, consultants and plant engineers are often under time pressure and must balance technical, regulatory and economic requirements.

This is exactly where Wilo comes in. Our application specialists support you early in the process to help you define the right solution for your applicable standards, technical requirements, fire protection plan and building structure.

Standards and regulatory requirements. A complex market.

The firefighting market is one of the most strictly regulated areas of building services. To meet diverse project and regulatory requirements, we consider the relevant standards and certifications applicable to each project, including:

  • EN 12845-1: European standard for the design, installation and maintenance of sprinkler systems
  • EN 17451: European standard for the design, assembly, installation and commissioning of pump sets
  • EN 12259-12: European standard for performance, design and testing requirements for sprinkler pumps
  • VdS: A certification widely recognised throughout Europe and highly relevant in Germany
  • NFPA 20: Internationally recognised standard for pumps and firefighting water supply
  • UL and FM: Globally recognised certifications and testing standards

Wilo components for firefighting systems—including pumps, control panels, and other components—are selected in accordance with project-specific requirements as well as relevant standards and certification requirements. Redundancy concepts designed to support high system availability are also taken into account.

Documentation, verification and acceptance readiness

A firefighting water supply system that complies with standards requires complete documentation and structured preparation for acceptance inspections. Wilo supports you in this process with:

  • Required testing and certification documents
  • Documentation in accordance with EN, VdS, NFPA, UL or FM
  • Preparation for acceptance tests and interface coordination
  • Support through to final commissioning

This helps ensure that the solution is prepared for inspection, acceptance and project handover.

Different buildings, different challenges in firefighting

Every application has its own specific requirements, but one thing is universal: A failure in the firefighting water supply system can lead to personal injury, operational disruptions and significant property damage.

Wilo develops solutions that support meeting these basic requirements while also addressing building-specific risks.

Firefighting for hospitals

Hospitals need reliable systems, as evacuation is virtually impossible in an emergency, and even brief outages pose an immediate danger to patients. In addition, complex building structures with many functional areas make it difficult to maintain a stable pressure supply.

Firefighting for industrial buildings

Industrial buildings place high demands on firefighting systems. Large indoor spaces and high fire loads facilitate the rapid spread of fire. In an emergency, shortcomings in firefighting measures can lead to significant production losses. Furthermore, sharp temperature fluctuations and large door openings can cause significant pressure fluctuations.

Firefighting for data centres

Data centres require secure firefighting concepts because sensitive electronics and high heat loads could cause major failures and data loss even with minimal disruptions. Complex server rooms require particularly precise system dimensioning.

Firefighting for airports

Airports pose unique challenges due to their extensive infrastructure, high passenger volume and strict security requirements, as any outage would immediately paralyse large parts of their operations. The wide variety of functional zones, from waiting areas to baggage claim areas, must be reliably supplied at all times.

What components make up a firefighting water supply system?

Typical components include main pumps, jockey pumps, control systems, valves, non-return valves, break tanks and drinking water separator stations and hydraulic integration, always depending on the standard and specific application.

How do you separate firefighting water from drinking water?

Where required, for example in Germany, by using certified separation stations such as Wilo‑GEP Fire‑H for hydrant systems and Wilo‑GEP Fire‑S for sprinkler systems.

What changes with EN 12845:A2 and why does it matter?

EN 12845:A2 now references EN 17451 and EN 12259-12, thereby tightening the requirements for firefighting water supply systems and pump sets. As a result, compliance is no longer only about individual components, but also about how the complete system performs and is documented.

With Wilo-FireSet, customers benefit from a solution developed to support these latest requirements, providing confidence in system design, installation and long-term operation.
