FLUX barrel pumps also called drum pumps are designed for transferring, emptying or dosing must existing fluids, from low to high viscosity products, these pumps are typically used for fluids that are supplied in containers such as 205 litre/45 gallon drums/barrels, 1000 litre containers called IBC's or Intermediate Bulk Container and also smaller containers 25 litre, 100 litre etc. By using a barrel pump we can avoid having to tip up the container in order to emptying it something than can often be quite dangerous and illegal thus using a drum/barrel pump is the safest and more efficient way of extracting liquid from a drum or container as wastage/spillage during the operation is next to nothing.


The pumping action and operation of the barrel pumps is quite simple, the pump tube is inserted into the opening of the container (bunghole) which typically is a 2 inch aperture, once the pump tube is immersed in the liquid the pumping action is done by the rotation of an impeller which is fitted at the bottom of the pump, the rotating impeller pushes the liquid up, towards the pump tube outlet and out of the discharge side of the pump.


There are several pump tube lengths each designed specifically for the various drums and containers available on the market, the most common are 1000 mm for 205 l drums, 1200 mm for IBC's and 700 mm for smaller containers - 25 litre jerry cans, 100 litre tanks etc.


The FLUX F427 pump range is available with a variety of hygienic connections, (1 1/2” Tri-clamp or RD 58x1/6), there is also a vast range of electric and air motors available in both single and 3-phase, these pumps can also be supplied as a complete pump kit containing a discharge hose, hand nozzle and compression glands depending on the specific model, carrying handles, fume glands and foot strainers are also available upon request. These sanitary pump range has been specifically developed for the food, beverage, and pharmaceutical industries, the Flux F427 food-grade pump is available with FDA and 3A certification which means this sanitary pump complies with the highest European and American hygienic standards, these pumps can also handle low viscosity food products with small solid particles i.e. spices within soups, pulp juice etc.

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.
The food grade connections for this pump range include; 1 1/2” Tri-clamp and RD 58x1/6. Please contact a member of our sales team if another connection type is required.
Please note that the standards vary by model. Our food grade barrel pumps comply with standards FDA and 3A for use in the food, beverage, chemical, cosmetic and pharmaceutical industries.
The body of the pump and the welds are polished and treated to very high standards, this greatly minimises dead zones. They are very easy to disassemble, making the process quick and pain free.
There are various motor types, including; air motor and mains powered electric. Selection is either a personal preference or due to site limitations. For instance, if an air compressor is not available on site, then a mains powered 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.
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.
Please be aware that the figures displayed relate to the largest pump from this range of products, not specific models. For details on viscosity for specific models, please refer to datasheets or contact a member of our sales team.
