BÖRGER ROTARY LOBE PUMPS
THE VERSATILE PUMPS
For use in potentially explosive atmospheres, pump units
have to be manufactured according to the European ATEX
guidelines (2014/34/EU). Börger manufactures “customized”,
ready-to-connect, ATEX-compliant, stationary or mobile
pump units exactly in line with your wishes and requirements.
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,
we deliver 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 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 completely without protec-
tion plates and liners. When pumping abrasive
media containing solids, the protection plates
and liners protect the pump casing from wear
and can be replaced in a matter of minutes.
4
The intermediate chamber and shaft seal
The large-volume quench chamber ensures
the highest degree of safety. The ideal
mechanical seal is selected depending on
the medium.
5
The carrier and timing gear
The high-quality and maintenance-free carrier
and timing gear guarantees a smooth and
even operation of the rotors. The result is a
long service life of the pump.

BÖRGER CONTROL TECHNOLOGY
Our engineers develop, program and build the ATEX-com-
pliant control technology tailored to your specific purpose
in our electrical engineering department. All monitoring
devices, e.g. temperature monitoring, electronic seal
monitoring or overpressure protection, are controlled
and monitored by the control technology which is easy to
operate.
TECHNICAL DOCUMENTATION
We prepare all necessary technical documentation for
you. Our technical editors work closely with the sales
engineers and our design department. Certified staff
guarantees compliance with all guidelines. We prepare
individual inspection records for the pump handover at
our own pump testing facility.

DURABLE AND RELIABLE
THE STATIONARY PUMP
CONSTRUCTION AND FUNCTION
(of this example pump)
1
The rotary lobe pump
The powerful rotary lobe pump is designed and
manufactured individually to suit your application.
2
Sealing and thermosiphon systems
The large-volume seal chamber provides space
for different sealing systems. In ATEX applications,
very often pressurized, double-acting mechanical
seals are used. The pressure is usually applied by
thermosiphon systems, upon request, also according
to API682 plan 53B.
3
The coupling guard
The ATEX-compliant coupling guard installed here
withstands a static load of up to 90 kg.
4
The motor
Very often, the pump is driven by an ATEX-compliant
electric motor. Other motor types are possible as well.
5
The base frame
Just like the entire pump unit, the base frame is
manufactured exactly in line with the customer’s
requirements. Upon request, it can be also equipped
with an oil drip pan underneath the pump and the
motor, with crane lugs or forklift pockets.

COMPACT AND VERSATILE
THE HAND CART PUMP
CONSTRUCTION AND FUNCTION
(of this example pump)
1
The rotary lobe pump
The powerful rotary lobe pump is designed and manufactured individually
to suit your application. The use of stainless steel rotors is possible for all
pump sizes.
2
The motor
In order to adjust the speed of the pump and, as a result, the flow rate to
the individual application, an ATEX-compliant variable speed motor or a
frequency converter can be used.
3
The filter technology
Depending on the pumped medium, it may be useful to install a filter
upstream of the pump.
4
The control technology
The pump is operated by the control unit. The control unit programmed
in line with the customer’s wishes and requirements, controls various
measuring systems (e.g. fill level measurement for dry run protection
or pressure measurement for overpressure protection) and ensures the
highest level of safety.
5
The chassis
We manufacture a perfectly suited chassis for each specific application
of the pump. Thanks to the forklift pockets, loading and unloading of the
hand cart pump is very easy.

FOR TERRAIN WHICH IS DIFFICULT TO ACCESS
MOBILE PUMP FOR TRANSPORT BY
FORKLIFT TRUCK
CONSTRUCTION
AND FUNCTION
(of this example pump)
1
The rotary lobe pump
A thermometer monitors the
temperature in the pump chamber
of the rotary lobe pump. An elec-
tronic pressure monitoring device
in the intermediate chamber
immediately indicates any leaks of
the mechanical seal. The pump is
classified as permanently techni-
cally tight (TA Luft-compliant).
2
Mechanical overpressure
protection
A bypass with safety valve protects
the pump from overpressure.
3
The flow meter
A flow meter measures the
flow rate. The flow rate is
shown on the control cabinet.
4
The base frame
The mobile unit is installed
on a base frame with forklift
pockets and crane lugs. An oil
drip pan is installed under-
neath the pump and the motor.
A level measuring device
checks the fill quantity of the
oil drip pan.

POWERFUL WITH LOTS OF SPACE
ON A CAR TRAILER
CONSTRUCTION AND FUNCTION
(of this example pump)
1
The rotary lobe pump
The powerful rotary lobe pump is equipped with a Variocap as mechanical
overpressure protection.
2
The filter technology
In order to separate solids during transfer operations, the mobile unit is
equipped with a filter system. Coarse solid particles are filtered out.
3
The control technology
The control technology is adapted to your individual requirements by
Börger's electrical engineering department. Naturally, easy operation of
the unit is ensured. Upon request, the control unit can also be operated by
a handheld transmitter.
4
The chassis
The chassis for mobile pumps is manufactured by our metal construction
department exactly in line with your wishes and requirements. Installation
on a roll-off container or a lowering frame is also possible. Of course, all
trailers are approved by the TÜV before delivery.
5
The roof construction
Our mobile units are equipped with different roof constructions. Whether
a tarp / roof bow-construction, aluminum roof or noise enclosure of the
entire unit – we make everything possible.
