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. Casing protection plates are not required. The pump with minimal

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.

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.

+ With or without casing protection

+ Almost pulsation-free, gentle pumping

of sensitive media

+ Volumetric efficiency that could not be

achieved before thanks to the perfect

rotorcasing combination

+ Large intermediate chamber for maximum

choice of sealing systems

+ Smooth running even at high

pressures

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.
