The BE series pumps are simple and robust and are characterised by their monoblock design. The drive unit, thanks to the hallow shaft and to the rear cover provided with an IEC flange, is directly fixed to the pump by creating a unique compact and light body. The new design, with smooth cover and fixing nut built in the rotors, improves the cleaning standard. The lobe pumps of this series are provided only with bi-lobe rotary piston rotors in S.S. 316 L or in antifriction alloy CY5SnBiM, which ensure an excellent volumetric efficiency and a smooth and regular transfer of several liquid or viscous products. In less demanding works, the BE pumps can replace the B pumps and, meeting the increasing demand of cheap lobe pumps with good sanitary standard, allow to widen the utilization possibilities of the OMAC lobe pumps.
