The small battery drum pump COMBIFLUX FP 314 is particularly suitable for pumping comparatively small quantities from containers such as cans or up to 200 litre drums. With IP 44, it is protected against splash water and therefore also ideally suited for outdoor use. The small diameter of the outer tube allows pumping even out of narrow openings. The sealless COMBIFLUX FP 314 is designed on a modular basis and can either be operated with the commutator motor FEM 3070 or the battery motor FBM-B 3100. This way several pumps can be operated in series with one motor. The intelligent cooling concept of the motor with double-walled housing ensures optimum air circulation and protects against the penetration of aggressive vapors.
