this must be precisely established by the company management.
If the personnel have insufficient knowledge, the company management must ensure good training that is
provided by the supplier or producer of the pump.
The company management must also ensure that the contents of this manual are fully understood by both
technical and service personnel, as well as persons responsible for ordering spare parts. In the following
sections they will find the necessary information about the identification of pump types, variants and
spare parts.
Dangers associated with non-compliance with safety instructions:
Non-compliance with the safety and operating instructions will lead to the invalidity of any form of
guarantee.
Non-compliance with the safety instructions can, for example, have the following consequences:
•Danger to persons due to electrical, mechanical and chemical influences.
•Failure of the specified maintenance and service procedures.
•Failure of the most important functions of the machine/installation.
•Danger to the environment due to the leakage of hazardous substances.
Safety-conscious working:

prevailing safety instructions are also of the utmost importance. The company management is responsible
for compliance with all prevailing safety instructions.
Impermissible actions:
The safe operation of the pump supplied is only guaranteed if it is used as intended and specified. This
pump was designed based on the specified operating conditions

Operating instructions B-Series
Version 2.4, En Page 11 of 81 21-10-2005
Safety instructions during the operation of the pump:
• The limit values of the area of application as mentioned in this manual must be respected.
• When cold or hot parts of the pump could cause danger they must be protected against inadvertent
contact.
• Protective devices for moving parts (e.g. shaft coupling) may not be removed during the operation
of the pump/pump unit.
• All leaking dangerous (explosive, toxic or hot) liquids (for example originating from the
mechanical shaft seal) must be removed to prevent any risk to persons or the environment. Local
regulations must also be complied with.
• Dangers resulting from the use of electricity must be avoided (see the standards and regulations of
the local electricity supplier).
• Pumps with a motor output of over 11 kW may never run against a closed valve. This causes
danger of explosion.
Safety instructions during maintenance, checks and repairs:
• Working on the pump/pump unit is only permitted when it has been put out of operation.
• To put an installation out of use follow the procedure described in these operating instructions, for
example the machine may no longer be under pressure and it must have fully cooled.
• Pumps and pump (units) pumping dangerous media must be cleaned and neutralised beforehand.
• Protect the drive motor during the whole working time against both inadvertent and unauthorised
switching on.
• When opening the pump follow all instructions for using the medium involved (for example
protective clothing, smoking ban, etc.).
• With repairs, in the interest of safety, parts supplied by the supplier or approved by him must
always be used.
• Modifications to the machine or the application are only possible after consultation with the
suppliers.
• The reliability of the pump/pump unit is only guaranteed when the pump is used for the
application and in the way it was intended on delivery.
• At the end of the activities all safety devices and protective equipment must again be installed and
made operative.
• Before restarting the pump/pump unit read the operating instructions through.

Operating instructions B-Series
Version 2.4, En Page 12 of 81 21-10-2005
Specific instructions for working with centrifugal pumps:
The pumps may only be used for the purpose for which they were sold. If you want to change the medium
you must ask the manufacturer/supplier if the pump is also suitable for the new medium.
This particularly applies for aggressive, toxic and/or media that are dangerous in other ways, and
with applications where an ATEX pump needed is.
Criteria for the suitability of the pump include:
•The construction of seals, in particular the mechanical shaft seal.
•The resistance of the material that comes into contact with the medium.
•The resistance of the material against the pressure and temperature of the medium.
Noise emission with centrifugal pumps (general):
Because the pump with or without drive gear is usually used as an installation component, permanent
installation on delivery is usually not applicable.
Noise measurements are therefore carried out on a random basis by us and our manufacturers (distance of
1 metre/1.6 metre height).
The measured values are usually below 70 dB(A)
No account is taken of the drive gear or piping with the measurements. The cavitation-free operation and
setup/installation of the pump according to the instructions is assumed.
Whoever works in an environment with a noise level of 85 dB(A) or
more must take personal protective measures.
2.2 Warrantee
We draw your attention to the fact that any guarantee becomes inapplicable and you must indemnify us
against any product liability claims from third parties if:
•Service and maintenance has not taken place according to the instructions, repairs were carried out by
personnel other than our own personnel, or carried out without our prior written permission.
•Modifications to the pump or pump (unit) have been made without our prior written permission.
•Not original BBA Pompen parts or lubricants other than specified have been used without our prior
written permission.
•The pump or pump (unit) has been used improperly, incorrectly, negligently or not in accordance with
the original nature and/or application.
With respect to drive gear and other external components (not parts of the pump itself) BBA Pompen
consents to the guarantee assessment of the supplier concerned.
All parts subject to wear are excluded from the guarantee.
The general terms of delivery in your possession are also applicable.

3.1 Description of pump
BBA self-priming centrifugal pumps are highly suitable for pumping clean and soiled liquids.
The pumps are provided with an open rotor and a wear plate that can be quickly changed.
Because few turning parts come into contact with the liquid, wear to the pump remains limited.
Large cleaning covers are also applied. The pumps have a modular construction and can be provided as:
standard modular cast iron with as options bronze and stainless steel.
It is possible to assemble different kinds of elastomers. It is also possible to assemble a large number of
different mechanical shaft seals. The shaft is provided as standard with C45 steel with optional stainless
steel.
The pumps can supplied as a bearing support design, and as a large number of pumps in a single block
and add-on design.
3.2 Application
The B-Series is used if one or more of the aspects below are required:
•self-priming
•large dirt passage
•wear-resisting
The B-Series is used in sectors including the following:
•industry
•shipping
•building work
•waste water
•the environment
•waterboards
•irrigation projects
•agrarian companies
•horticulture
The B
-Series is not designed for the food industry, but can be used when there are no
special requirements from hygienic standards. The materials used for the selected pump
variant must in any event a
lways be checked beforehand for their suitability for the
foodstuff concerned.
The B-Series is suitable for pumping viscous liquids to 50 mm²/s (cst).
The maximum liquid temperature is 180 degrees (in ATEX zones the max. temperature depends on the zone
and category). This is also dependent on for example: material types, liquid, working pressure, and setup of
pump, see technical information.

For correct use of the pump attention must be devoted to materials, the environment (ATEX zone),
liquid, viscosity, temperature, working pressure, number of revolutions etc.
• The application and area of use are limited depending on the selected pump version. This was
selected in consultation between the user and supplier based on the information the supplier
disposed of at the time of the purchase.
• The supplier is not responsible for damage to the pump/pump unit that is the consequence of
missing and not specified information at the time of purchase (such as, for example the
composition of the liquid, environment, temperature, number of revolutions, quantity and size of
the solid components, etc.).
• The pump/pump unit may under no circumstances be used for another application than that for
which it was originally purchased and installed.
• The changing of the application may only take place after consultation with, and with the written
agreement of BBA Pompen BV.
3.3 Working of the pump
The self-priming centrifugal pump distinguishes itself from the normally priming centrifugal pump by its
air processing capacity. The pump housing of a self-priming pump is constructed so that a part of the
pumped liquid flows back to the suction side. When air is drawn this is mixed with the liquid in the pump
housing. The mixture of air and liquid can be pumped through the rotor. The mixture will be separated
after leaving the rotor. The air is removed through the pressure line, while the heavier water returns
through a type of return pipe in the pump housing and falls to the suction side. This process continues
until all air has been pumped out of the suction line. The pump then forces out the water that was drawn in
through the pressure line.
A condition for starting this process is that before the pump is started up the pump housing is fully filled
with liquid. Filling can take place through the inspection cover on top of the pump. The big advantage of a
self-priming centrifugal pump is that no separate vacuum pump is needed to pump the air out of the
suction line.
The disadvantage, however, is that the performance of a self-priming centrifugal pump is usually lower
than that of a normally priming centrifugal pump. This is because a part of the pumped liquid in the pump
housing is returned to the suction side.
