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.
