The Flux F/FP 425 barrel emptying pump is the ideal solution for transferring expensive or hazardous chemicals as it empties 99.98% of the drum’s content , meaning it leaves next to no product in the container making this pump the most cost effective and safe way to transfer or extract liquid from a drum or IBC container.

Another great feature on this pump is the fact that it has an integrated foot valve which the operator can easily close before taking the pump out of the drum avoiding spillage as well as preventing any backflow from going back into the container, this could reduce wastage considerably when one pump is being used to empty several drums, this also makes the FP 425 barrel pump one of the safest options when handling hazardous or flammable liquids.

Flux pumps are available in several different tube length sizes, 1000 mm suitable for 205 litre drums and 1200 mm for IBC containers, there is also a 700 mm standard tube set for other smaller containers.



-          Empties up to 99.98% of all liquid from containers. Some pumps can leave as much as 6% of contents. With this design only 0.05 litres will remain in an IBC or Drum.

-          Non Return valve prevents liquid from flowing out of pump tube, meaning drips and any wastage is kept to a minute amount when using between containers

-          Designed to be easily stripped for cleaning and sanitization in-between batches

-          Designed to be used in conjunction with a hand nozzle without stopping pump

-          Mechanically sealed ensuring full containment of vapours, and reduce contamination with atmosphere

-          Fully ATEX Approved for use in the most hazardous of areas

-          Shaft bearing is grease lubricated for long life design

-          As pump is of centrifugal design, pumping motion is pulse free

This pump is designed to be used with all types of:

-    Petroleum Products such as diesel, heating oil, machine oil, engine oil

-    Acids such as Formic Acid (Up to 85%) Concentration, MEK, Ketone, Butane, Octane, ethanol, butanol, acetate, toluene, Isobutanol, and Xylene

Motors used with pump: 

F460 Ex/F460 Ex El, Maximum Flow of 115L/min and Discharge Head of 8M

Kit Contains:


The standard tubeset lengths are 700 mm for smaller containers - 25 litre jerry cans, 100 litre tanks etc, 1000 mm for 205 litre drums and 1200 mm for IBC's. Other bespoke lengths are available on request.
Firstly, always check the compatibility of the materials available against the fluid being pumped. The main materials to check are the tubeset, impeller, mechanical seal and o-ring. It may be that more than one material is suitable for your fluid and selection could be based on the application type. For instance; PP, PVDF, Stainless steel and aluminium are all suitable for water. If it is a simple transfer application, then the most cost-effective material will be best. However, if it involves another variable to consider such as high temperature, then an alternative material may be a better selection.
There are various motor types, including; air motor, mains powered electric and battery. Selection is either a personal preference or due to site limitations. For instance, if mains power or an air compressor are not available on site, then a battery motor is the obvious choice. The power of the motor will be down to the application details, such as viscosity and flow rate required. An Atex motor will be required if the fluid is flammable or if the pump will be installed in a hazardous area.
A mechanically sealed pump is recommended for abrasive, crystallizing, sticky and high temperature fluids. A sealless type pump is be recommended for all other fluid types.
ATEX is an abbreviation of “Atmospheres Explosibles”. It is a regulation set out by the European Union to ensure the safety of products that are used to handle flammable products or are installed in environments containing flammable gases, vapours, mists or combustible dusts. For instance, if the pump is being installed in an explosive environment, then only the motor needs to meet the Atex standard stopping it from causing a spark during operation and igniting the atmosphere. However, if the fluid being pumped is flammable, then the pump will also need to meet Atex standards to ensure that no sparks are caused inside the pump itself when the fluid goes through it. It is crucial that an Atex rated pump or motor are used for applications involving explosive environments or flammable fluids, using a non-Atex pump or motor in these situations is extremely dangerous and contravenes health and safety standards.
