Flux F 300 Series pumps are designed for light to medium-duty applications, particularly when portability, precision and ease of use are critical. These pumps are compact, lightweight and therefore ideal for emptying small-volume containers (25–100 litres). However, longer F 300 pumps (up to 1200 mm) are also available for emptying larger barrels and IBC’s.
Furthermore, the centrifugal design efficiently transfers low-viscosity fluids up to approx. 250 mPas. And with a range of materials to choose from, there is always an F 300 pump available for most common liquid dispensing applications, in safe areas.
In contrast, F 400 Series pumps are larger and stronger, with a range of unique design features making them suitable for heavy-duty operations. In addition, these pumps deliver higher flow rates & discharge pressure, handle more viscous fluids (up to 1,000 mPas depending on configuration), and are compatible with a wider range of drive systems—including air-operated motors, brushless electric motors and ATEX-certified models.
Custom immersion depths (up to 3,000 mm) are available to order. Moreover, there is a wider range of F 400 pump models available, including food-safe pumps, 99.9% emptying pumps and mixing pumps.
To summarise – F 300 pumps are the preferred option for those needing a simple, cost-effective but robust transfer pump, for intermittent use. These pumps prioritise low weight, minimal maintenance and ease of handling.
While the F 400 Series are serviceable, long-life designs, suitable for heavy-duty, process-critical roles requiring maximum throughput, extended system integration, custom sizing and additional certification.
The Flux JuniorFlux F 314 pump is a centrifugal pump that operates on the axial-flow principle, where a high-speed impeller generates flow within the pump’s central axis, to move the fluid upward through the tube and out via the discharge outlet. The impeller is positioned at the low-level pump inlet and is therefore directly submerged in the liquid. It is connected to an electric drive motor via a strong driveshaft.
What differentiates this pump from alternative designs is its seal-less construction, whereby the liquid flows directly along the drive shaft and through the bearing surfaces. This removes the requirement for a mechanical shaft seal – a benefit in terms of leak resistance and reduced maintenance requirements.
