Battery motor drum pump FBM 4100

The FLUX FBM 4100 is the world’s most powerful cordless drum pump motor, delivering 420W of performance—equivalent to corded units—without the cable hazard. Featuring a brushless (BLDC) motor with 80% efficiency, it is the first “intelligent” motor with dry-run protection and automated batch filling

Models

The FBM 4100 is available in two primary ventilation concepts, each offered in Core and Pro versions:

  • Ventilated (Standard): Delivers a maximum power of 420 watts and is rated IP24.
  • Closed (A-Version): A fully enclosed motor providing 260 watts of power with an increased IP44 protection class, ideal for aggressive environments with harmful vapors.
  • Core vs. Pro: The Core version includes standard intelligent features like dry-run protection and batch filling. The Pro version adds a 24 V interface for connecting external devices like start/stop buttons or flow meters.

Applications

The motor is designed for diverse industrial environments:

  • Remote Locations: Ideal where no mains connection is available or where cables would be a hindrance.
  • Aggressive Environments: Used in electroplating or chemical handling where encapsulated electronics protect against corrosive vapors.
  • Mobile Stations: Suitable for mobile collection trays or the mobile filling of lubricants.

How to Use

  • Operation: Features an intuitive menu and a rotary knob for 10-stage speed control.
  • Batch Filling: Users can pre-set and repeat filling processes across six memory slots.
  • Visibility: An integrated LED drum light and an illuminated LCD display allow for clear monitoring of fill levels and settings.
  • Compatibility: It is compatible with FLUX 400 series pumps and can even be used with other manufacturers’ pumps via an adapter.

Benefits

  • High Efficiency: Uses brushless (BLDC) technology to achieve 80% energy efficiency and maintenance-free operation.
  • Extended Runtime: Two 18 V/4 Ah batteries provide up to 60% longer runtime than comparable motors, emptying up to eleven 200-liter drums on a single charge.
  • Intelligent Safety: Includes activatable dry-run protection to prevent pump damage and a battery management system (BMS) for longevity.
  • Ergonomics: Provides a high weight-to-power ratio for comfortable one-handed operation.
  • Universal Compatibility: While optimized for FLUX 400 series pumps, its versatility allows it to be used on standard competitor pump tubes—including Jessberger, Lutz, and Dino using an adapter. This cross-brand compatibility makes it an ideal universal upgrade for existing barrel pump inventory.
