The brushless FBM-B 3100 battery motor was developed for the wireless operation of the drum pump Combiflux, which is suitable for pumping comparatively small amounts out of containers, such as canisters or drums with a volume of up to 200 litres. The motor is splash-water-protected thanks to a silicone cover and operates fully electronically with stepless speed adjustment. The open handle shape with suspension function enables flexible grasping and one-handed operation. The intuitive arrangement of the operating controls, which are highlighted in colour, further enhances the ergonomic handling.
