FLUX Introduces the New FBM 4100 Battery Motor for Drum and IBC Pumps

FBM 4100 is a next‑generation battery motor designed to bring greater mobility, safety and efficiency to drum and IBC pumping operations. Built around a powerful brushless drive and using the superb Einhell Power X‑Change battery platform, FBM 4100 delivers strong performance without the limitations of cables or fixed power sources.

Cordless power for industrial environments

The FBM 4100 battery motor delivers impressive runtime – empty up to 28 drums or 5 IBCs with 2 x Einhell 4.0 Ah PLUS batteries*. This makes it ideal for production areas, maintenance teams and mobile service operations where flexibility and freedom of movement are essential.

The high-efficiency brushless motor provides the longest possible service life, while the modular Einhell battery management system allows users to choose from 2.5 to 8 Ah battery packs, for reduced weight or extended runtimes.

_{*Measured with water (20 °C) in open flow condition. Tolerance: ± 10 %. Example (approx. 10,000 rpm): 5,500 l in 32 min → approx. 28 × 200-litre drums or 5.6 IBCs. Measurement configuration: F 430 PP 50/38 (pump tube). Note: The values refer to the above setup and are for comparison purposes only. Other media, temperatures or configurations (e.g. hose length/diameter, fittings) will produce different results.}

Smart digital controls

A standout feature of the FBM 4100 is its integrated LCD display, giving operators clear visibility of speed, battery status and operating mode. The standard CORE motor also includes:

• Six programmable dispensing presets – enjoy cost-effective, accurate filling without the need for flowmeters or switching amplifiers

• Selectable dry‑run protection helps prevent pump damage

• Integrated LED work light improves visibility in low‑light or enclosed areas

• Fully encapsulated electronics

• Optional PRO version with 5-pin connection – allows direct connection of remote start-stop button and provides power for flowmeters, level controls and other process devices.

Designed for versatility

The FBM 4100 is available with a choice of two housing. Choose from a ventilated IP24 model for maximum performance. Alternatively, choose an enclosed IP44 version for environments affected by corrosive fumes or steam. Both are engineered for demanding industrial use and are compatible with all FLUX F 400 series pump tubes. Additionally, they are compatible with VISCOPOWER F 570 pumps for higher‑viscosity media (<2,500 mPas).

Furthermore, this class-leading new battery motor is also compatible with many third-party pump tubes, using an adaptor (sold separately).

FBM 4100 showcases FLUX’s continued focus on performance, quality, operator safety and workflow efficiency. This is an approach also reflected by our recently introduced mobile pump stands.

A new standard in portable pumping

With its combination of cordless power, intelligent controls and robust industrial design, the FBM 4100 sets a new benchmark for portable drum and IBC pumping. It offers businesses a flexible upgrade path that enhances productivity, while reducing handling risks and operational constraints.
