As 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 positive 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.
