Börger lobe pumps are fitted as standard with seals
mechanics specially designed and optimized for this type of
pump, which completely seal the pump body in relation to
transmission, resp. to the intermediate chamber (see Chapter Ä
3.1.6 “Intermediate chamber (quench)” on page 42). THE
joints are replaced by the working body easily, quickly
and without dismantling the machine.

Mechanical seals are available in different combinations of two materials.

If your Börger machine is equipped with special seals, you

find all the necessary information in the documentation
additional information in the appendix.

3.1.6 Intermediate chamber (quench)

ATTENTION !

Risk of damage to the transmission if

fixed shutter of the intermediate chamber!

If the vent is blocked or if there is a blockage and the trim

mechanical is damaged, the pumped liquid leaks from the body
work cannot escape through the intermediate chamber and
for this reason it will infiltrate the transmission. The transmission may then be
damaged.

— The safety opening of the intermediate chamber is used for

tightness check of the mechanical seal and must not

be closed.

— Any overflow from the intermediate chamber indicates a

waterproofness problem.

Product Description

The pump and transmission compartments are separated into

series by an intermediate chamber filled with liquid.

The liquid prevents the seals from running dry

mechanical in case of heat absorption and collects the liquid
pumped which enters the intermediate chamber in the event of a leak
a mechanical seal. This so-called “ Quench ” protects
also the transmission against any damage due to
infiltration of pumped liquid.

Fig. 2: Example Classic FL Series The connection between the shaft and the lobes is also lubricated by
the liquid from the intermediate chamber, and thus protected against
corrosion.

To compensate for the increase in pressure in the event of increasing

temperatures, the intermediate chamber has a screw
side drain with vent (1, side in case of standing model,
Ä
For this purpose, refer to Chapter 3.1.7 “Construction forms,
mounting positions” on page 43). In some applications such as
submerged devices, the chamber vent
intermediate can be extended by a tube extension
in the visible part.

As an option, the Börger machine can be delivered with a cap

vent in the filling opening (2) of the intermediate chamber. In the
event of liquid overflow due to a fault
sealing, it should be possible to remove the vent plug almost without
pressure. This model does not have a side drain screw. Only the
optional vent plug should be used to seal the filler opening (2).

Any overflow from the intermediate chamber indicates a fault

sealing.

On the transmission side, the intermediate chamber is sealed

by DUO lip seals.

3.1.7 Construction shapes, mounting positions

Depending on the pump type and mounting position, the oil sight glass,
vents/drains, filling openings and drain openings for the transmission
and intermediate chamber
are placed differently.

3.2 Description of the operating mode

1 Suction chamber
2 Intersection of the suction and discharge chambers
3 Discharge chamber

Börger lobe pumps are positive displacement, self-priming and valveless.

The lobes rotate in opposite directions thanks to a motor

external, via two parallel shafts.

The geometry of the lobes allows total separation between the

suction chamber (1) and the discharge chamber (3).

The synchronous rotation of the pairs of lobes creates a vacuum at the level
on the suction side determined by the direction of rotation of the motor. This
vacuum draws liquid into the pump compartment.

The dynamic transition from the suction chamber to the chamber

delivery (2) allows delivery with low pulsations, or even without pulsations if the
lobes are helical. The liquid
pumped is discharged on the pressure side (3) by the rotating lobes fitted into the
discharge pipe.

The symmetrical structure of the lobe pump makes it possible to reverse the
delivery direction by changing the direction of rotation, if this is
possible from a technical point of view on the installation.

A rotation of the motor allows up to six fillings to be delivered, depending on the

type of lobes.

4. Brides

If your Börger two-shaft machine was delivered without flanges (with

standard square flanges at the inlet and outlet), fit suitable flanges as follows:

Use:

— Appropriate flange screws, — Elastic

washers for fixing the flange screws, — Gaskets made of material tolerated

by the pumped liquid.

— As standard, use O-rings to insert into the appropriate O-ring groove
at the inlet/outlet of the square flange.

Flange flat gaskets can also be used as an option, e.g. ex. in the
AgrarTec field.

5. Tighten the flange screws, with which you install the

flanges at the inlet and outlet evenly and crosswise

so that the tightness of the connection is ensured.

— When doing so, be careful not to damage the gaskets and spring washers
and not to expel the flat rubber flange gaskets (NBR, EPDM, FKM).

4.4.3 Assembly, entry and exit

ATTENTION !
There is a risk of damage from improperly installed piping systems!

Börger machines are of robust construction and dimensioned

for significant constraints. However, they should not
under no circumstances be used as a fixed point for driving. THE
tensions thus generated in the pipe could crack
the most fragile parts of the installation or the hard solder cords, even if the
vibrations linked to the operation of the
Börger machine are of little importance.

— Pipes as well as added or integrated elements

(valves, check valves etc.) must not exert
stress on the machine and flange connections.

— Make sure that there are no alignment errors between the

flanges of the machine and the pipe.

— All added elements must be supported as closely as

possible from the device, in accordance with regulations
general techniques in force.

ATTENTION !
Danger of considerable damage from cavitation!

Through cavitation, lasting damage to the machine

Börger are not excluded.

— To avoid cavitation, ensure that the Börger machine

must not overcome any suction height or that
this is as low as possible.
— The available NPSH value of the installation (NPSHavailable /
NPSHA) must always be greater than the necessary NPSH value of
the pump (NPSHrequired / NPSHR), that is to say:
NPSHeff. > NPSHnéc. + 0,5 m (1,64 ft) resp. NPSHA > NPSHR
+ 0,5 m (1,64 ft).
— Depending on the application, for example in the presence of liquids
discharged gases, and depending on the construction of the pipes,
it may be wise to provide evacuation valves at the high points of
the piping system.
— Ensure that no air cushions can form
in front of and behind the pump.

For attaching inlet and outlet flanges to pipes or fles

xible, it is necessary to have suitable joints, the connections

for flanges requiring flat gaskets. These joints must be
resistant to pumped liquid.

The type, model, nominal diameter and pressure rating of

the connection flange or any special connections have
been specified with the contract. Only the counter flanges/connections
compliant are authorized for assembly, under the use of seals
appropriate.

The pipes to be connected must comply with the specifications

appearing in the order (material, value DN, PN,
NPSHA etc.).

Blockage and imbalance

ATTENTION !
Risk of material damage due to blockage and imbalance of
the control shaft!

Insufficient cleaning and foreign bodies can cause lasting

material damage to your Börger machine.
— Make sure that no long fiber elements or other foreign bodies
which could lead to blockage of the control shaft reach
the working body.
— Make sure that, e.g. insufficient cleaning (adherent remains
of the pumped liquid) or the presence of foreign bodies are
not the cause of an imbalance.
— If necessary, take appropriate precautions (install a crusher
and/or stone trap upstream).

Environmentally
hazardous substances
ENVIRONMENT !
Danger from improper handling of products dangerous for
the environment!

Improper handling of environmentally hazardous products,

particularly in the event of improper disposal, can lead to
considerable damage to the environment.
— When carrying out installation, repair and maintenance
operations, take particular care to ensure that water-polluting
substances, e.g. greases and lubricating oils: do not
seep into the ground; do not reach the pipes.

— These substances must be collected, stored,

transported and disposed of in a suitable container.
— When handling oils, fats and other
chemical substances, follow the instructions in force as well
as the safety data sheets of the manufacturers of these
products, in particular with regard to storage, handling, use
and disposal.
— During all work, respect legal obligations
regarding waste reduction and compliant recycling/disposal.

Reduction in discharge flow!

Börger GmbH recommends a prior check of the condition of the lobes in

the event of a reduction in the delivery rate.

Replace the lobes when they show obvious signs of wear.

— If the result is unsatisfactory and the discharge flow

does not recover after fitting new lobes, check the axial wear plates.

If one of the axial wear plates on the front flange or transmission side shows
signs of wear, replace it, as the rear wear plate on the front flange side can
be turned over once before being replaced.

If there is still some play between the tips of the lobes and the body wall after
installing new lobes, we recommend - if there is still no pumping power - to also
replace the pump body.

Before replacing wearing parts, you can take advantage of the possibility of
increasing the rotational speed of the pump motor, and therefore the delivery rate.

— On electric motors, this may correspond to the increase in frequency at your

frequency converter (also beyond the mains frequency).

On certain types of motor, the rotation speed can for example be modified by
adjusting the rotation speed of the motor (steering wheel on the adjustable
gear motor or throttle in the case of the combustion engine) or the quantity
of oil (hydraulic motorization).

— Respect the load limits in Ä Chapter 3.3

“Technical characteristics” on page 51.

6.2.2 Filling level and replacement of lubricant

ATTENTION !
Risk of significant material damage in the event of incompatibility
between the liquid in the intermediate chamber and the
liquid !

Loss of sealing due to incompatibility between liquid

of the intermediate chamber and the pump liquid can cause
considerable material damage.

— Observe the detailed instructions and notes concerning the

replacement of lubricants in the list of lubricants (which forms
an Ä Chapter 9.8 “List of lubricants” on page 202),
integral part of these instructions, as well as the instructions in
the technical data sheet concerning the lubricants used.
— Concerning the liquid in the intermed chamber
diary, note the following points: In case of infiltration of
intermediate chamber liquid in the working body of the
machine and therefore in the process, a rare situation, but which
cannot be completely excluded, the compatibility of materials
(especially the material of the O-rings) must be
ensured, as is the liquid in the intermediate chamber
with the pumped liquid.

NOTICED !
Behavior of the intermediate chamber liquid

The liquid in the intermediate chamber must not fall below the minimum
threshold marked on the filling level display.

— The liquid in the intermediate chamber may, due to the

function and depending on the operating temperature, increase
during service to the edge of the filling opening. However, it is
only in the event of overflow that it
should suspect a sealing problem at the level of
the mechanical seal.
— A slow and minor loss of liquid from the intermediate chamber
may occur due to condensation as well as
through the lubrication of the mechanical seal.
— A sudden, regularly significant or complete loss of
liquid from the intermediate chamber in operation under
Vacuum is the indicator for a mechanical seal leak.

ENVIRONMENT !
Danger due to improper handling of dangerous products
for the environment !

Improper handling of products hazardous to the environment,

particularly in the event of improper disposal, can
lead to considerable damage to the environment.

— With regard to installation and repair operations

and maintenance, take particular care to ensure that water
polluting substances, e.g. fats and
lubricating oils: do not seep into the ground; do not reach
not the pipes.
— These substances must be collected, preserved,
transported and disposed of in a suitable container.
— When handling oils, fats and other
chemical substances, follow the instructions in force
as well as the safety data sheets of the manufacturers of
these products, particularly with regard to storage,
handling, use and disposal.
— During all work, respect legal obligations
regarding waste reduction and compliant recycling/disposal.

Check the oil level Lubricant replacement intervals can greatly

and the liquid from the room vary depending on the conditions of use and be considerable
intermediate shortened, for example in the presence of high humidity
high temperatures, strong temperature variations or an aggressive
atmosphere.

Exemple Lobes PL 100 Premium

Pump body depth A = 55 mm

Length of stainless steel lobe B = 54,5 mm

— 1 - Lobe
— 2 - Heel to lobe
— B - Lobe length

Undercut calculation

Underdimension (U) = Depth of the pump body - Length of the stainless steel lobe = 0.5 mm

Half of the undercut (U/2) = Undercut (U): 2 =0.25 mm

Therefore, the rotating grain support must be unscrewed

by half the undersize (U/2) = 0.25 mm!

screwed in using the Multitool (12). When doing this, however,
make sure that the O-ring (1) is not damaged and is not
pushed out of its seat.

24. Check the mobility of the lobes.

— If a rotating grain holder has been tightened too much, the lobes
rub at the axial wear plate on the transmission side and the
shaft is difficult to turn.
Disassemble the lobes and unscrew the corresponding rotating
grain support by 1 /12 turn (or a groove).
— The lobe protrudes from the flange side of the pump if the support
rotating grain is insufficiently tight. In this case of
figure, the lobe rubs, when the ear nuts are
tightened, against axial wear plate on the front flange side.
If necessary, screw the rotating grain support a

The accessories offered by Börger GmbH are as varied as
the areas of use of the Börger machine.
If your Börger machine was delivered with accessories, the
instructions for use are in the appendix or in the packaging for
machines with original packaging.

8.1 Frequency variator

The machine can be used with a frequency converter.
Only frequency converters providing constant torque are suitable
for this Börger machine.

NOTICED !
External cooling of the motor

If the motor frequency is set to a very low value,

external cooling of the motor may be necessary.

8.2 Monitoring devices

8.2.1 Protection against dry running

Any prolonged dry running — that is, operation without

pumped liquid — should be avoided. This particularly concerns
elastomer lobe pumps. The heat released by the
Friction damages the components of the lobe pump.
Regarding processes where the risk of dry running cannot be
be excluded (when the lobe pump containers are empty,
for example), we recommend the installation of a device
protection using temperature monitoring or a conductivity sensor
as a temperature level control device
filling, a regulator must be connected in both
cas.

if the temperature increases in the pump body due to

the absence of pumped liquid and reaches a defined value, a
command will stop the lobe pump or the installation equipped with a
PT100 temperature probe in order to avoid any dry running of the
lobe pump.

The PT100 temperature probes can also be used to

monitor the temperature of optional cable glands. This is by
essential example when using such a filling
sealing in areas subject to the risk of explosion.

Conductivity sensor Conductivity sensors acting as filling level monitoring device

measure electrical conductivity
at the pump inlet and shut off the lobe pump/installation
through appropriate control when a preset value
is not reached.

8.2.3 Overpressure protection valve with bypass

The presence of a bypass with overpressure protection valve
(safety valve) allows the discharge line to be briefly and completely
closed without stopping the pump.
When the discharge line is locked, the pump
discharges the liquid to the suction side via the protection valve
against the overpressure which opens. The causes of overpressure
can be eliminated.
When the pressure drops or the discharge line is

9.8 List of lubricants

Domaine d'application This list of lubricants is part of the instructions for use; except
otherwise indicated, it is valid for all common models
of Börger pumps, Powerfeed devices, grinders, Bio select devices
and submersible mixers, if no separate agreement has been made
agreed.

In certain individual applications, specificities may have

be agreed. In this case, this list of lubricants is no longer
valid, it is replaced by the new agreed elements,
Ä to Chapter 9.8.7 “Customer validation of lubricants
according
special (example)” on page 214.

For the motors supplied, the user manual as well as the

Manufacturer's list of lubricants apply.

ENVIRONMENT !
Danger due to improper handling of dangerous products
for the environment !

Improper handling of products hazardous to the environment,

particularly in the event of improper disposal, can
lead to considerable damage to the environment.

— With regard to installation and repair operations

and maintenance, take particular care to ensure that water
polluting substances, e.g. fats and
lubricating oils: do not seep into the ground; do not reach
not the pipes.
— These substances must be collected, preserved,
transported and disposed of in a suitable container.
— When handling oils, fats and other
chemical substances, follow the instructions in force
as well as the safety data sheets of the manufacturers of
these products, particularly with regard to storage,
handling, use and disposal.
— During all work, respect legal obligations
regarding waste reduction and compliant recycling/disposal.

9.8.1 Transmission Börger

Oil quality

Only oils containing active substances allowing

improve corrosion protection and resistance to
aging and to reduce wear in the transmission, are permitted for Börger
transmission blocks.

At the same time, transmission oils must present the

following quality characteristics:

— Compatibility with lip seal and body materials

transmission.

— Compatibility with remaining oil used in the factory.

— Sufficient viscosity in the relevant temperature range.

ATTENTION !

Risk of material damage and loss of warranty

case of using lower quality lubricants!

Oil classifications and viscosity of lubricant supplied by

factory, indicated in the technical data sheet of the machine, must
be respected.

The lubricants used must meet quality standards

indicated above. Otherwise, the guarantee granted
by the Börger company is no longer valid. Deviations are only permitted
after agreement with Börger.

If the actual conditions of use during commissioning or

subsequently differ from those indicated in your order,

the need for a lubricant change should be investigated.
This measure requires permission from Börger.

All lubricants that can be used in transmissions

Börger are listed in on Ä Chapter 9.8.4 “Types of oils”
page 208. However, only the respective manufacturers are responsible for
the quality and compatibility of their products.

According to the manufacturer's instructions, the indicated lubricants may

be delivered worldwide in the required quality.

Annex

Oil drain
The lifespan of the oil, but also that of the transmission as well as
general operational safety, depend on the degree of purity of
the lubricant.
Therefore, it is important to ensure that the oil in the
transmission is always clean!
It is essential to follow the instructions in the Börger machine
operating instructions when changing oil/lubricant.

Even when using oil of the same type as that already contained in
the transmission, the residual quantity of the old oil should be as
low as possible.

NOTICED !

Do not mix oils of different types and produced by different

manufacturers!

If necessary, the manufacturer of the new oil must confirm

compatibility with the remaining old oil.
If the composition of the new oil deviates significantly from that of
the oil previously used, for example with regard to additives, the
entire used oil must be disposed of from the transmission. To do
this, carefully flush the transmission with new oil. Transmission
oils must not be contaminated by other substances or detergent
residues such as petroleum, for example. Therefore rinsing with
petroleum or any other detergent is not permitted.

9.8.2 Liquid without pressure

All liquids that have good lubricating properties and do not attack
any of the materials with which they come into contact can be
used as pressureless liquids.
Compatibility with any remaining previously used non-pressure
liquid must be checked before topping up/refilling.

204 www.boerger.de / www.borger.fr BA-Classic CL_fr-FR, 17/01/2019

Annex

To avoid as far as possible any damage to the level

of the transmission, and this also in the unlikely event of liquid
infiltration without pressure into the transmission following a
incorrect maintenance, it is necessary that the non-pressure fluid is
also compatible with the transmission oil. See
below Ä Chapter 9.8.4 “Types of oils” on page 208.

ATTENTION !

Risk of material damage if unsuitable lubricants are used!

In the event of liquid infiltration without pressure into the pump/

cutting compartment and thus into the process, situation
rare, but which cannot be completely excluded, compatibility
materials (O-rings) must be ensured, as well as the
compatibility of the liquid without pressure with the pumped liquid.

ATTENTION !

Risk of material damage and loss of warranty

case of use of unsuitable lubricants!

Feed fluids such as ultrapure water, antifreeze agents, silicone

oils, automatic oils, diesel and methanol are unsuitable as

as lubricants.

The lubricants used must meet quality standards

indicated.

ATTENTION !

Risk of material damage if unsuitable lubricants are used!

Models for particular applications and/or with

special sealing materials can be filled with
special lubricants.

In this case, this filling has been specially agreed/

checked for the machine model delivered and appears in the data sheet
technical. When topping up/refilling, it is suitable
to use exclusively the same liquid without pressure to avoid
material damage which, depending on the case of application, may
be considerable.

9.8.3 Oil Properties

Operating temperatures

Synthetic oils have a wider operating temperature range than

mineral oils, the difference in viscosity
due to the temperature being however lower (viscosity index
higher). In addition, synthetic oils have higher thermal stability and
ignition temperature.
For this reason, with liquid temperatures above 80°C (176°F),
resp. in ATEX units in the
transmission and as a non-pressure fluid, use only quality
synthetic transmission oil
industrial with an ignition temperature higher than
200°C (392°F).

In the model, one can alternatively also use

synthetic high-power hydraulic oil with an ignition temperature
above 200°C (392°F).
The use of oils in contact with EPDM is not permitted. Here an
alternative lubricant should be chosen for the model,
resp. for the circulation system.
For use in the food industry and

oil, transmission oils and non-pressure fluids

used must be food safe (e.g. NSF H1).

NOTICED !

Special lubricants can be delivered after appropriate agreement.

In this case, the agreed limit values are
valid.

All values given are recommended guideline values. To find out

the operating temperature ranges
indicated by the lubricant manufacturer as well as other information
regarding the properties of the oil, please consult the
technical data sheets of the respective lubricant manufacturer
concerned.

Duration of oil use

Regarding the duration of use, follow the corresponding operating

instructions for your Börger machine.
