Where trust and reliability become security

In the world of critical infrastructure, reliability is not an option—it is a necessity. At Holzhauer-Pumpen, we have been guided by this principle since 1969: mutual trust and unconditional reliability.

Reliable fire protection starts with the right technology and a partner you can count on. We supply precisely tailored pump units for fire protection systems, exactly matched to your requirements. From the customized design and development of fully equipped fire extinguishing systems to on-time delivery, we offer solutions for demanding fire protection applications.

Modular System

Why Holzhauer?

Manufacturer-independent solutions for the best results

Holzhauer is a manufacturer-independent system provider.

For your project, we select the most technologically advanced components and solutions available on the market, always tailored precisely to your requirements and offering maximum flexibility.

This guarantees maximum efficiency and longevity for your fire extinguishing systems.

Plug & Play: Minimal Risk, Maximum Speed

Prefabricated, modular container and skid solutions.

Construction projects in critical environments are highly complex. Our turnkey stations are tested at our factory and simply need to be connected on site. This minimizes interface risks, shortens installation time, and conserves your resources.

100% Tested Safety (Certified Testing)

In-house, certified test benches and 100% testing by qualified technical staff.

In the field of critical infrastructure, there can be no room for “maybe.” Every unit leaves our factory only after a successful full-load test run on our certified test benches—documented according to the highest international standards. Additionally, Holzhauer Pumps is certified according to DIN EN ISO 9001:2015 (Quality Management).

Deep expertise in standards (compliance)

Over 56 years of experience and a thorough understanding of international technical requirements as well as insurance standards (FM, NFPA, VdS, EN 12845, NFPA, and others).

Holzhauer-Pumpen ensures that your system is not only safe today but also meets all regulatory and insurance requirements. Our comprehensive documentation is audit-proof and meets the highest project standards, always tailored to your requirements and needs.

Full-Service & Single Point of Contact

A single point of contact for your project, from planning through maintenance.
