Firemiks AB, founded in 1979 as a Swedish family business, has grown into a well-recognised name in the global fire and safety industry. Today, operated by the third generation and supported by strong industrial partners, the company continues to specialise in the development, production, and worldwide distribution of water-driven volumetric pump proportioning systems under the FIREMIKS brand. Firemiks takes pride in combining flexibility and precision—offering both customised solutions tailored to individual project requirements and a range of standard models designed to meet stringent international standards.
At the heart of every FIREMIKS system is its simple and reliable operating principle. The units operate on the principle of positive displacement, where both the water motor, driven by the extinguishing water flow, and the concentrate pump, powered by the water motor, work in tandem to inject the concentrate into the water flow. This method ensures a precise dosing relationship determined by the volumetric interaction between the water motor and the concentrate pump. This dosing relationship remains largely unaffected by pressure, flow and viscosity variations, within the specified limits as detailed in each units’ performance data. The system operates efficiently with the extinguishing water as its sole power source, utilizing an atmospheric concentrate tank with gravity feed to the dosing pump.
A cornerstone of the FIREMIKS design is the compact multi-vane volumetric water motor, first developed in the late 1970s and continually refined over the decades. This design provides an excellent balance between efficiency, durability, and size. For example, in a typical 3% proportioner, the water motor handles about 30 times the volume of the concentrate pump, all within a compact footprint. The modular approach allows Firemiks to match the water motor with a wide range of high-quality concentrate pumps, each chosen to suit different application needs and fluid properties.
The transition from AFFF to SFFF presents significant challenges for the entire industry, particularly in handling different, including higher, viscosities. Regulatory bodies are mandating the shift to PFAS-free concentrates, which necessitates a reassessment of proportioning systems for compatibility. SFFF foams, often non-Newtonian and with viscosities ranging from 1cP to 5-6000cP, require a thorough understanding of their properties. Traditional proportioners struggle with accurate flow calculations under these new conditions. However, FIREMIKS systems, designed to accommodate a wide viscosity range, provide a reliable solution, handling also viscosities in the higher end of this range, without the need for constant recalibration, due to changes in temperatures, aging of the concentrate or future replacement to new concentrate with another viscosity
Looking ahead, Firemiks AB is poised to adapt to further advancements in firefighting foam technology. The shift towards fluorine-free SFFF is expected to continue over the next 5-10 years. Additionally, there is a growing interest in lower dosing rates, such as 1% and even as low as 0.3% or 0.5%. Another major challenge is the development of systems capable of effectively extinguishing Li-Ion battery fires. Firemiks AB is committed to evolving its systems to meet these new requirements and ensure the highest standards of safety and performance in firefighting technology.
