BÖRGER ROTARY LOBE PUMPS
THE VERSATILE MOBILE PUMP
Frequently, situations arise, in which a mobile pump is
required. Thanks to its compact design, the chemical re-
sistance and the self-priming operation, the Börger rotary
lobe pump is ideally suited for this application. Mobile
pumps are versatile and very often indispensable.
Each Börger rotary lobe pump is configured for its specific application using
a modular principle. This also applies to the mobile pumps. In this respect,
Börger delivers everything from a single source. The entire unit is designed
and manufactured for the corresponding application, including the mobile unit,
the pump technology and the control unit.
OPERATING PRINCIPLE
Rotary lobe pumps are self-priming, valveless, positive displacement pumps.
The synchronized rotation of the rotor pair creates a vacuum on the priming
side of the pump. This vacuum draws the liquid into the pump chamber. The
medium is pumped into the pressure area due to the rotation of the rotors.
If the direction of rotation is changed, the flow is reversed.
CONSTRUCTION
1
The quick-release cover
Access to all wetted parts by simply
loosening four ring nuts.
2
The rotors
Large selection of high-quality rotors
for almost pulsation-free pumping of
the medium.
3
The casing protection
Depending on its size, the BLUEline
pump is available with and comple-
tely without protection plates and
liners. When pumping abrasive media
containing solids, the protection
plates and liners protect the pump
casing from wear and can be repla-
ced in a matter of minutes.
4
Intermediate chamber and
shaft seal
The large-volume quench chamber
is oil-filled and ensures the highest
degree of safety. The ideal mechani-
cal seal is selected depending on the
medium.
5
The carrier and timing gear
The high-quality and maintenance-
free carrier and timing gear guaran-
tees a smooth and even operation
of the rotors. The result is a long
service life of the pump.
