Unlike our conventional pumps that are installed vertically through the top cap of the IBC, the Miniflux instead enables fluid extraction directly from the low level outlet valve. As a result, it offers a clear advantage in height-restricted areas, or when using stacked IBCs. Furthermore, it significantly enhances flow rate when compared to gravity draining. Additionally, this compact IBC pump weighs just 1.2 kg and incorporates our quick-release motor coupling. Therefore, manual handling is extremely easy – the pump and motor can be connected and disconnected in seconds.
Industrial Miniflux is based on our highly successful F 430 pump design and incorporates a high-precision ETFE axial impeller and ceramic-oxide mechanical seal. Therefore, any F 400 series motor can power the pump – flow rates up to 240 LPM are possible, depending on the motor selection.
Furthermore, the use of ETFE and stainless steel 316 ensures long-term resistance to corrosion, high temperatures and chemical degradation. And with full ATEX certification, Miniflux is suitable for handling highly flammable liquids, or use in Zoned areas. Not only that, you can use it to pump liquids that contain solids in suspension, or viscous fluids up to 1,000 mPas.
Whether you are dispensing flammable solvents in a paint factory, or transferring ethanol and glycerol blends in a cosmetic lab, the Miniflux provides power, flexibility and convenience. It also reduces manual handling risks and safety issues associated with lifting IBC’s, therefore helping meet stringent health and safety standards.
The answer to this question depends on the following factors:
Firstly, the visual differences between these two pumps are obvious – they are designed for completely different installations. F 430 pumps are vertical designs, for installation through the top cap of an IBC, whereas Miniflux is a horizontal pump for direct connection to the floor-level IBC outlet valve. F 430 pumps are available in five different materials, whereas Miniflux is only available in stainless steel 316. Therefore, Miniflux is more limited in terms of material compatibility.
However, apart from these differences, the two pumps are extremely closely related. They are both axial, centrifugal pump designs that use an identical 38 mm impeller. They both utilise an identical mechanical seal. Furthermore, they are both modular designs, powered by our F 400 series drive motors. Therefore, they deliver identical performance.
Finally, the Miniflux offers certain benefits in terms of flexibility, portability and lower weight. This results in easier installation and reduced manual handling risk. However, the Miniflux is more limited in terms of options – for instance, F 430 is available with optional semi-axial impellers (for higher discharge pressure) and wider range of accessories, including inlet strainers and back-flow valves.
The Miniflux is an axial-flow centrifugal pump, suitable for handling low viscosity media up to 1,000 mPas. Fluid flows to the pump inlet under the effect of gravity and atmospheric pressure – the pump cannot create suction. A robust ETFE (or stainless steel) impeller, housed in the stainless steel casing, rotates at high speed (up to 10,000 RPM) creating flow in a direction parallel to the driveshaft. This enables the media to move smoothly through the pump body, before being discharged at a 90° angle to the inlet.
The axial impeller creates high flow (up to 240 LPM) and relatively low discharge pressure (up to 1 Bar), depending on the drive motor selected. Take a look at F 430 series pumps if higher discharge pressure is required (up to 3.2 Bar).
The Miniflux industrial pump utilises a mechanical seal behind the impeller. This ensures the shaft support bearings are completely isolated from the medium, preventing contamination, corrosion and ingress of solid particles. Note however, that the mechanical seal is a wear part that should be replaced preventatively, as failure can lead to product leakage through the bearings. We recommend that the seal is replaced every 3 years, depending on hours run.
