The FBM 4100 is a powerful cordless drum pump motor designed for efficient liquid transfer in industrial environments. Delivering 420 W of power in the ventilated version and 260 W in the enclosed version, it uses the Power 36 V battery system to provide performance comparable to a mains-powered motor while maintaining the convenience and flexibility of cordless operation.
Equipped with two 4 Ah batteries, the FBM 4100 offers an exceptionally long runtime, allowing continuous operation across multiple drum transfers. Under optimal conditions, it can empty up to 28 × 200-litre drums with water at 20°C and free flow, or approximately 11 × 200-litre drums per battery charge under typical operating conditions using a hose and nozzle.
The FBM 4100 is also the world’s first smart drum pump motor, featuring advanced functions such as batch filling and dry-run protection for safer and more controlled operation. The Pro version includes an interface connection, enabling integration with external start/stop controls or additional peripheral devices.
Designed for versatility, the FBM 4100 is compatible with all FLUX Series 400 drum pumps and VISCOPOWER F 570 progressive cavity pumps. With the use of adapters, it can also connect to most commercially available pump units, making it a flexible solution for a wide range of pumping application.
