For more than 75 years, FLUX has been recognised as a pioneer in drum pump technology. Today, the brand continues to define industry standards with the launch of its newest product: the FBM 4100, an innovative, intelligent, battery‑powered drum pump motor powered by industry-leading Einhell lithium-ion batteries. FBM 4100 is designed to transform the way process engineers, maintenance teams and operators transfer, dispense and meter liquids from barrels and IBC’s.
A High‑Performance Cordless Breakthrough
Modern production environments demand flexibility, efficiency and safety. The FBM 4100 delivers with its 36 V brushless motor with 420 W rated power output, providing performance comparable to its mains‑powered counterparts, but with the added freedom to work anywhere. Despite its impressive power, the entire motor-including batteries weighs just 2.8 kg, providing excellent mobility for field technicians, production staff and service teams.
Designed for use in applications in construction, chemicals, food & beverage, water treatment, electroplating and more, the FBM 4100 is resistant to corrosive media and handles a wide variety of fluids effortlessly – from disinfectants and degreasers, to additives, oils, and even corrosive chemicals such as sulphuric acid. Encapsulated electronics ensure reliable operation, even in the most demanding conditions.
Intelligent Control for Precision and Safety
What truly sets the FBM 4100 apart are its patented smart features, engineered to reduce waste, improve accuracy and increase process control:
Dry‑Run Protection
This switchable safeguard shuts off the motor automatically when the container is empty – protecting pump components, reducing wear, extending maintenance intervals and improving overall process safety.
Programmable Batch Filling
A major advancement for operators who need precise, repeatable filling volumes. Users can program up to six predefined filling quantities, selectable directly via the integrated LCD display. This enables efficient, accurate metering without the need for a separate flowmeter, minimising set‑up time while reducing complexity and cost.
Intuitive LCD Display with 10% Speed Adjustment Increments
The clear, intuitive display lets users adjust motor speed in precise 10% steps, providing optimal flow rates and safe operation for specific tasks.
Exceptional Runtime and Practical Performance
As with any cordless product, battery runtime is critical. The FBM 4100 delivers outstanding endurance thanks to two 18V Einhell 4 Ah Plus batteries:
- At 80% speed, a single charge can empty eleven 200‑litre drums or
- 2.2 IBCs (1000 litres each)—totalling up to 2,200 litres per charge
Need longer runtimes? Simply upgrade to larger batteries. FBM 4100 is compatible with any Einhell battery up to 8 Ah capacity. And with a maximum open-flow delivery rate of up to 220 l/min, it provides the performance required for high‑demand workflows, making it ideal for busy production lines, mobile service operations and chemical dosing tasks where mobility and speed are essential.
Unmatched Compatibility and Modularity
FLUX understands our customers often operate mixed equipment fleets. Therefore, the FBM 4100 is engineered for ultimate flexibility:
- Compatible with FLUX F 400 series drum and container pump tubes
- Suitable for more viscous media when combined with F 570 progressive cavity pumps
- Optional adapters for connection of other manufacturers‘ pump tubes, making the FBM 4100 an excellent upgrade for users seeking to improve their existing pump performance.
- IP 24 (internally-cooled) and IP 44 (externally-cooled) variants are available depending on environmental conditions, for instance atmospheres containing steam or corrosive fumes.
Pro Version for System Integration & Automation
For more advanced applications, the FBM 4100 Pro offers even greater functionality. This model includes:
- A 5‑pin plug for external start/stop control
- A 24 V power supply for peripheral devices, including flowmeters, level sensors or automatic dispense nozzles
This functionality allows process engineers to integrate the FBM 4100 into automated plant systems, enabling smarter, leaner, and safer workflows—particularly useful in chemical dosing, batch processing and chemical mixing applications.
Designed for Real‑World Industrial Conditions
From tough chemical handling jobs to outdoor or mobile service applications, the FBM 4100 is built to perform under pressure. Unique battery covers protect against splashing liquids and aggressive vapours, ensuring longer life in challenging environments. Pre‑configured pump sets—including hoses and hand nozzles—are also available for quick deployment directly out of the box.
Continuing a Legacy of Innovation
The launch of the FBM 4100 reinforces FLUX’s reputation for engineering excellence, reliability and customer‑focused design. After more than 75 years producing high‑quality pumping solutions in Germany, FLUX remains a trusted partner for chemical processors, pharmaceutical manufacturers, cosmetic producers, and food industry operators worldwide. With close to 100 countries served and a global network of around 70 distribution partners, the company continues to provide industry-leading support to customers worldwide.
Discover the Future of Mobile Fluid Handling
The FBM 4100 is more than just a cordless motor—it is a leap forward in performance, efficiency and functionality. Whatever the task, it provides operators with confidence, flexibility and measurable performance benefits.
