CombiFlux pumps are the World’s best, light-weight, low viscosity drum pumps for emptying smaller containers and for infrequent use. Thanks to the unique Flux spiral shaft bearing, this pump consequently delivers class-leading service life with minimal maintenance requirements.
Furthermore, the Flux CombiFlux FP 314 battery drum pump is a modular, robust industry-proven solution. Its seal-less design with ETFE axial impeller addresses two common failure points in many drum pumps—seal failure due to lack of preventative maintenance, and impeller wear from use of lower quality impeller materials. By eliminating the mechanical seal entirely, the FP 314 can subsequently handle limited dry-running without damage, simplifying maintenance requirements and reducing downtime caused by seal failure and fluid leakage.
Moreover, the interchangeable motor coupling, featuring a dual quick-release clamps, means that a single FBM-B 3100 battery motor, or FEM 3070 electric motor, can be used to power multiple pump tubes. This design reduces up-front investment costs, optimises equipment use, speeds up dispensing processes and additionally, prevents cross-contamination between different fluids. For facilities managing batch production and handling many different chemicals, this modular architecture significantly increases process efficiency and ROI.
The answer is – probably. You can use CombiFlux FP 314 pump tubes with a wide spectrum of common fluids at temperatures up to 80°C*. Furthermore, with material options that include polypropylene (PP), PVDF and 316 Ti stainless steel, you can choose the most suitable material for your application. Common media include:
Components such as the ETFE impeller, PTFE / carbon composite bearings and Hastelloy C driveshaft are selected specifically for their high resistance to pitting, crevice corrosion and stress cracking, therefore ensuring long service life, even in tough chemical handling environments.
In addition, the pump can handle viscous fluids up to 250 mPas and high density fluids up to 1.3 SG, under continuous duty use. Only pump higher viscosity, or higher density fluids for short periods, as they drain the battery quickly.
Most importantly, note this battery drum pump is not suitable for use in Zoned areas, or for pumping highly flammable media with a flashpoint below 50 degrees C. Furthermore, the pump is not approved for handling edible food products and beverages.
*Depending on material selection
Firstly, the distinction between the Flux F 310 and F 314 lies primarily in their shaft sealing technology and intended use. The F 310 pump design incorporates a mechanical seal, which creates a physical barrier between the pumped media and the driveshaft and its support bearings. Therefore this design is compatible with abrasive fluids containing entrained solids. Addition of an inlet strainer is beneficial when pumping liquids containing larger solid particles.
In contrast, the F 314 is a seal-less design, where the fluid enters the inner tube and flows around the driveshaft via axial force generated by the impeller. This eliminates frictional wear associated with dynamic seals, along with the requirement for o-rings immersed in the pumped media. Consequently, this pump can withstand limited dry-running, and virtually eliminates the need for lubrication and preventative maintenance. The F 314 is therefore ideal for corrosive, pure, non-abrasive and solids-free fluids. Pumping abrasive, or solids-entrained liquids with the F 314 should be avoided, due to rapid, potentially excessive bearing wear that will significantly reduce pump working life.
The CombiFlux FP 314 battery drum pump utilises axial, hydrodynamic fluid movement facilitated by an open, centrifugal impeller, spinning at high speed. When power is applied via the motor (either FBM-B 3100 or FEM 3070), the impeller rotates within the fluid path, generating a pressure differential that pushes the liquid outwards and upwards towards the pump discharge port. Furthermore, operation relies on the effect of atmospheric pressure to push liquid to the pump inlet. This type of pump cannot create a negative inlet pressure to draw fluid to the inlet.
Fluid is conveyed upwards between the inner and outer pump tubes. Liquid will also enter the inner tube, lubricating the shaft bearings. The liquid can only escape through low-level relief ports connecting the inner and outer tubes, once the motor is switched off. This design equalises pressure between the inner and outer tubes, reduces turbulence and promotes a stable flow profile.
Upon reaching the outlet, the fluid exits the system under controlled pressure, with discharge rate governed by motor speed and discharge hose (or pipework) back-pressure. When the container is nearly empty, air will enter the pump. No more fluid can be removed from the container and the motor must be turned off. Any residual liquid drains naturally back into the container through the inlet. Liquid also drains from the inner tube through the relief ports, ensuring complete evacuation without requiring the pump to be inverted.
To summarise, this pump provides smooth, low pulsation delivery, uniform flow and reduced energy consumption, particularly when used in conjunction with the brushless, soft-start battery motor. The result is effective, efficient fluid transfer.
