The new BLUEline Rotary Lobe Pump
FOR PURE MEDIA
BLUELINE NOVA CLEAN
The BLUEline Nova rotary lobe pump sets new standards in pump technology and
achieves unrivaled volumetric efficiencies. The newly developed DIUS rotors in the
flow-optimized pump chamber combined with an optimized pump gear unit ensure
perfectly smooth running even at high pressures.
The “clean” version of the BLUEline Nova has been designed for conveying pure,
non-abrasive media. A casing protection is not required. The pump with minimum
dead space can be cleaned according to the hygiene procedures CIP (Cleaning-In-
Place) and SIP (Sterilization-In-Place).
The development of the BLUEline NOVA pump has
benefited from our experience of more than 30 years in
pump manufacturing. With the help of computer flow
simulations and physical test bench hours, we were
able to improve the pumps even further. To this end,
the geometries of the pump chamber and the rotors
were perfectly matched.
The result: A volumetric efficiency that has never
been achieved before combined with perfectly smooth
running even at high pressures.

AT A GLANCE
+ With or without casing protection
+ Almost pulsation-free, gentle pumping
of sensitive media
+ Highest volumetric efficiency thanks to the
perfect rotor-casing combination
+ Large intermediate chamber for maximum
choice of sealing systems
+ Smooth running even at high
pressures
LARGE SEAL CHAMBER
The large seal chamber provides space for
different sealing systems. Whether for quenching,
flushing or buffering – the sealing system is
adjusted perfectly to the requirements of the
pumped medium. This ensures the longest
service life and highest productivity.
In addition to the tried and tested Börger seals,
special seals of other manufacturers can be
used upon request.

FOR ABRASIVE MEDIA
BLUELINE NOVA TOUGH
For conveying abrasive media containing solids, we have developed the
Nova tough. A radial and axial casing protection protects the pump casing.
The protection plates and liners are perfectly integrated into the pump
casing in a flow-optimized design. Thanks to an innovative fastening
system, also the “tough” version of the Nova pump ensures excellent
efficiency. In case of wear, the casing protection is replaced quickly and
easily thanks to the MIP
®
design (Maintenance in Place).
The newly developed one-piece DIUS rotor ensures an
almost pulsation-free pumping even at high pressures.
The wide sealing surface prevents a backflow of the medium
and guarantees a volumetric efficiency never achieved
before as well as an optimized suction performance.
Whether made of stainless steel or elastomer, the DIUS
rotor does not need a cover disk. Integrated O-rings
prevent that the basic core of the elastomer rotor comes
into contact with the pumped medium. The shaft remains
unwetted – for longest service life and simple cleaning.

UNLIMITED POSSIBILITIES
CUSTOMIZED. APPROPRIATE. DURABLE.
DESIGN COMPLIANT WITH GUIDELINES
All Börger pumps and pump units can be manufactured according
to the European ATEX guidelines (2014/34/EU) for use in potentially
explosive atmospheres.
In addition, an API-676-compliant design, production according to the
FDA regulations or a technically tight pump design according to the
German TA Luft requirements are possible.
WITH DIRECTLY FLANGED MOTOR
The BLUEline Nova can be used with different
drives. Upon request, the drive is directly flanged to
the pump. Due to the elimination of the coupling and
the base frame, the unit is even more compact.
STATIONARY. MOBILE. SUBMERGED.
Thanks to the compact design, Börger rotary lobe pumps
can be used as stationary, mobile or submerged units.
High flow rate with smallest footprint.
For this design, a base
frame is not required.
