*Performance data

Empties a 200 L water‑filled drum in under one minute (20 °C, free outlet). Real‑world results vary with liquid, temperature, delivery head, hose size/length and accessories.

• 420 W brushless motor delivers extra power – performance is similar to a 600 W brushed motor
• Cordless productivity: faster, easier container changeovers and fewer delays
• All‑day runtime: empty multiple drums / IBCs per charge – keep workflows moving.
• Safe: eliminates cable trip hazards, protects the operator from accidental electrical shocks.
• Smart: Programmable dispensing for cost-effective, repeatable filling.  Dry run protection prevents accidental damage
• Right design for the job: choose ventilated for max performance, or enclosed for fume ingress protection.
• Intelligent: Connect flow meters, level sensors and FLUXTRONIC® controls directly via 5-pin connector.
• LED barrel light for visual indication of remaining liquid.

• Core:  Variable speed control, LED work light, dry‑run protection, batch dispensing function with 6 programs.
• Pro: All Core features plus PRO interface for direct device connectivity and remote start/stop.
• Standard 420 W ventilated models: IP 24 ingress protection
• 260 W sealed models: IP 44 ingress protection for corrosive atmospheres
