Flux Pumps Combi AdBlue Rechargeable Drum Pump Kit – Portable Solution

The CombiFlux AdBlue kit is a portable, rechargeable drum pump solution for transferring AdBlue®, DEF, glycol and similar low-viscosity media directly from 200-220 L drums or smaller containers. This lightweight kit combines a seal-less polypropylene pump and a high-efficiency, brushless battery motor. The CombiFlux pump kit delivers mobility, chemical resistance, and precise flow control. Designed for use in remote locations, or when trailing power cables are undesirable- the Combiflux battery pump can be used anywhere. Examples include using the pump in workshops, vehicle yards and maintenance depots. The pump is also ideal for waste transfer stations and for mobile chemical dispensing from trucks or vans. Furthermore, this is not a throwaway pump. The CombiFlux rechargeable drum pump kit features our double-walled brushless motor with an IP44 fume-resistant enclosure. Consequently, this pump kit suits heavy-duty industrial use and performs well under challenging field conditions. The slim 32 mm pump tube fits into narrow container openings. Additionally, the soft-start, variable-speed motor controls dispensing to prevent splashing. The modular design with quick-release motor connection provides ultimate flexibility. Furthermore, pump tubes are available in a range of lengths and materials. And finally, CombiFlux is backed by Flux's renowned German engineering quality.

1. Seal-less architecture for optimal long service life

   Firstly, the CombiFlux pump has no mechanical seal or o-rings in contact with the media. Therefore this seal-less design reduces maintenance requirements and easily handles urea-based fluids and AdBlue®. In addition, the robust pump tube eliminates common failure points resulting from seal wear or ammonia degradation. 

2. Spiral shaft bearing delivers enhanced axial stability

   Flux’s unique PTFE/carbon spiral bearing reduces shaft deflection and additionally ensures concentric rotation. This precision design reduces mechanical loads and turbulent flow at higher motor speeds, consequently leading to greater operational lifespan.

3. Brushless variable speed motor – full control at your fingertips

   The FBM-B 3100 motor offers stepless speed adjustment, thereby allowing the user to fine-tune flow from approx. 8-33 LPM. This enhances operator safety and dispensing precision, especially when filling smaller, narrow-necked containers. Furthermore, operators can finely adjust flow rates in real time with the integrated dial. The soft-start function protects mechanical components and additionally reduces wear over long term use.

4. Rechargeable convenience –  Pump up to 1,250 L per charge

   The 18V Li-ion battery delivers impressive performance: up to 1,250 litres of AdBlue® can be transferred on a single charge. In addition, it’s cordless freedom delivers true portability. Consequently, this makes the CombiFlux ideal for outdoor use, for example, at vehicle depots and mobile workshops. Furthermore, the battery can be fully charged from empty in just 30 minutes, using the smart charger included. 

5. 32 mm pump – ideal for small container openings

   The lightweight, slim pump tube is designed for insertion into smaller, narrow-necked containers and confined tank openings. However, CombiFlux is also suitable for 200-220 litre drums and even 1000 litre IBCs, when fitted with a 1200 mm long pump tube.

6. Modular quick-connect system – fast assembly and easy cleaning

   The motor is attached to the pump with quick-release clamps, for rapid assembly or cleaning. Therefore, pumps can be swapped out or replaced, without the use of tools. Furthermore, this design can future-proof your pumping operations – purchase additional pump tubes for different liquids and use one detachable motor to power them.

          Simply disconnect and reconnect the motor within seconds for cost-effective, contamination-free liquid dispensing from multiple containers. Remember, pump tubes are              available in different lengths and materials, therefore covering a range of container sizes.

      7. Scientifically proven materials for AdBlue® handling

        Finally, all wetted parts—including the PP pump tube, stainless steel driveshaft, ETFE impeller and FKM hand nozzle seals—have been laboratory tested for compatibility            with AdBlue® per ISO 22241. Therefore, long-term resistance to urea, ammonia vapour and hydrolysis is guaranteed, under real-world conditions.
