Boerger has surprised the world of pumps with a new generation of its BLUEline rotary lobe pumps, the BLUEline Nova, with the high-tech pump available in six sizes and with flow rates of up to 110 m3 /h. The German manufacturer promises not only excellent volumetric efficiency but also maximum choice of sealing systems.

Boerger is well-known for its high-quality rotary lobe pumps with flow rates of up to 1,450 m³/h. Presenting the new generation of its BLUEline rotary lobe pumps, Alois Börger, Managing Director of Boerger, said, “The development of the BLUEline Nova has benefited from our 30 years of experience in pump manufacturing. With the help of computer flow simulations and physical test bench hours, we were able to improve the pumps even further.”

Mr Börger said the rotors and casing were made for one another. This newly developed one-piece DIUS rotor ensures an almost pulsation-free pumping at pressures of up to 12 bar, while the wide sealing surfaces of the screw-profile rotor prevents backflow of the medium.

“Boerger has also modified the pump chamber to utilise the dual-lobe rotor to its full potential. The geometry of the inlets and outlets, as well as the wrap angle of the casing, were particularly optimised. We were able to considerably improve the volumetric efficiency of the pump. To this end, we have adjusted the pump chamber to the rotor geometry in a flow-optimised design,” Mr Börger said.

The BLUEline Nova comes in two variants: with or without protection plates and liners. In its clean version, protection plates and liners are not required. The pump with minimum dead space can be cleaned according to the hygiene procedures, CIP (Cleaning-In-Place) and SIP (Sterilisation-InPlace).

In its tough version, the pump is equipped with protection plates and liners for pumping abrasive media containing solids. With a new innovative fastening system, the ‘tough’ version of the Nova pump ensures the best volumetric efficiency ever achieved in a rotary lobe pump.

In case of wear, the protection plates and liners will be replaced quickly and easily due to its MIP® design (Maintenance in Place). The large seal chamber of the BLUEline Nova provides space for different sealing systems, therefore ensuring connection of external supply systems is possible, and without issues.

Different motors can also be selected for driving the BLUEline Nova rotary lobe pump. Upon request, the drive can be directly flanged to the pump and, due to the elimination of the coupling, the unit is now even more compact. In addition, this version does not require a base frame.

Like all Boerger pumps, the BLUEline Nova rotary lobe pumps can be manufactured according to the European ATEX guidelines for use in potentially explosive atmospheres. An API-676-compliant design, production according to the FDA regulations, or a technically tight pump design according to the German TA Luft requirements, round off the various options for versatile applications.
