Issue 2017-01 Basic Information
2. Basic Information
2.1 Notes on the operating manual
This operating manual has been prepared to meet all product-specific and user-related
requirements of the law and of all relevant regulations and rules, technical standards,
directives and agreements.
The manual includes important information on the functioning of MAGSON magnetically
coupled centrifugal pumps and how to use, install, service and dispose of them.
In the following, the magnetically coupled centrifugal pumps are referred to as “pump”.
Before putting the pump into operation, carefully read the operating manual and make
sure that it is always ready at hand to all users of the pump.
Complying with all instructions of this operating manual is an essential prerequisite to
guarantee the safe operation and maintenance of the pump.
Make sure that all operators and service technicians have fully read and understood the
manual before they start working at or with the pump.
2.2 Validity of data
All technical data, dimensions and indications of weight etc. were valid at the day when
this manual went to press. Specifications listed here may differ from the actual design of
the pump but will not modify any relevant information in principle.
2.3 Purpose
MAGSON pumps are designed to function as centrifugal pumps delivering fluids.
2.4 Use to the intended purpose
MAGSON pumps must only be used to deliver fluids of watery viscosity without coarse
solids and have to be submerged all the time for cooling. So the fluids meant to be
delivered are
#water and aqueous solutions,
#acids,
#bases,
#similar fluids free of magnetizable metal particles.
Do not use the pump to deliver
#inflammable or explosive fluids,
#solid containing or abrasive fluids,
#fluids being used to process food because the pump has not been certified according
to FDA or EC 1935/2004 standards.
If you want to deliver solids-bearing or abrasive fluids, please contact the pump’s
manufacturer.

8
2.5 Anticipated misuse
The pump is misused if
#it is used other than to the intended purpose;
#it is operated beyond its defined limits;
#it is used to deliver inadmissible fluids like fluids containing magnetizable metal
particles or coarse contaminants, for example.
2.6 Limits of use
Dimensional limits
For dimensions of the pump see ∑Dimensioned drawings in the Appendix page 30 ff.
For technical data of the pump see ∑Appendix page 30 ff.
Other limits
Media temperature MAU BG1 (8/110): 0 to +40°C,
MAU BG2 (12/330): 0 to +70°C
Pumps made of PP must not be used at temperatures below 0°C as the material starts to
become brittle.
2.7 Warranty and liability
The pump must only be used to the intended purpose specified by this operating manual.
Inappropriate operation or insufficient service and maintenance will cancel the right to all
warranty claims.

Issue 2017-01 Technical Information
4. Technical Information
4.1 General description
MAGSON magnetically coupled centrifugal pumps are non-self-priming centrifugal pumps
made of plastic and built in horizontal single-stage monoblock design. A magnetic
coupling connects the pump to the motor and transmits the power of the motor to the
impeller.
Pump housings, impellers, inner magnet sheaths and rear casings are made of plastic.
The rear casing hermetically seals the fluid from the ambient atmosphere. Because of
magnetic power transmission, there is no need to mechanically seal the shaft. So, in
contrast to mechanically or gland sealed pumps, any leakage at the shaft is completely
impossible. Motor and pump are hermetically sealed and supposed to be used submerged
within the liquid.
4.2 Nameplate
The nameplate of the pump not only specifies its operating data but also its type and
serial number. Please indicate all these data when making an inquiry, reordering parts
and, in particular, when ordering spare parts.
For further information, contact your pump's supplier or the manufacturer.
4.3 Type codes and materials
The type code on the nameplate informs you about the pump materials in contact with
fluid.
