FLUX drum pumps for explosion-risk areas

3/15/2018

Now for operating temperatures of up to 60 °CAs a rule the use of drum pumps in explosion-risk areas is limited to ambient temperatures of up to 40 °C. Now, with the new combination of commutator motor F 460 Ex (HT) and pump FP 424 Ex S (HT), FLUX has pushed the operating temperature limit up to 60 °C (140 °F).

This has been possible by adaptation of the design whilst at the same time retaining the familiar positive FLUX product characteristics. The motors now have the Ex designation II 2 G E EX De IIC T5 Gb and the respective pumps Ex II 1/2 G c IIB T3 each according to the applicable ATEX Directive 2014/34/EU.

The impulse for this new development at FLUX was provided by an increasing number of inquiries for relevant Ex applications from the petrochemical, oil and gas sectors as well as from countries with higher natural ambient temperatures, such as those of the Middle East or southern Europe.
The new (HT) versions of the FLUX commutator motor F 460 Ex and sealless drum pump FP 424 Ex S guarantee reliable operation for extended periods of use too. They also provide the maximum level of safety for pumping materials in explosion-risk areas with high ambient temperatures of up to 60 °C
Motor and pump will be presented to the world for the first time at the HI Technology and Industry Expo exhibition in Herning, Denmark from the 3rd to 5th of October 2017.

Now available as an Ex versionThe drum emptying system VISCOFLUX lite is now available as an Ex version. It is designed for higher-viscosity media which are just capable of flowing. The new explosion-proof variant is now suitable for use in explosion hazard areas of zone 1 and for pumping the most varied flammable media (zone 0/1).

The Ex version of VISCOFLUX lite opens new opportunities across a diverse range of industries, such as chemicals or surface finishing technology. For example it is suitable for supplying machinery and fast-running plant with lubricating greases in zone 1. Alternatively it can be used for pumping zone 0/1 flammable media such as various base materials for paints and lacquer manufacturing as well as numerous coatings and fillers.

Quick to install, conductive components Contrary to the standard version of VISCOFLUX lite, the individual components of the Ex version (Ex-marking II 1 G IIB TX), pump centring plate and follower plate including process seal as well as the compressed-air hose are made of conductive or static dissipative materials. Comprehensive and precise potential equalization can be carried out over suitable connections for earthing wires. The system is quick to install, requires little space and due to its low build can also be used in working spaces with low ceilings.

Residual volume in drum up to less than 1 %To continuously and gently transport higher-viscosity materials which are just capable of flowing, FLUX engineers use eccentric worm-drive pumps. In combination with a follower plate, a vacuum is created during pumping causing the follower plate to lower. In doing so the process seal of the follower plate hermetically seals the remaining material thus preventing unwanted emissions and changes to the product.

Even if the pumping operation should be interrupted, a maximum degree of process reliability is guaranteed. Finally, almost no material remains on the wall of the drum. Users have the benefit of an almost complete emptying of the drum and thus an efficient utilisation of the material. As with the VISCOFLUX and VISCOFLUX mobile, with VISCOFLUX lite the residual material which remains in the drum is up to less than 1 %.

Launch at the ACHEMA 2015The VISCOFLUX lite in Ex version will be available from the ACHEMA 2015. Come and visit us during 15. and 19. June at our stand (hall 8, stand E10) and convince yourself of the qualities of this drum emptying system.
