Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
The main task of technical committees is to prepare International Standards. Draft International Standards adopted
by the technical committees are circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 5199 was prepared by Technical Committee ISO/TC 115, Pumps, Subcommittee SC 1,
Dimensions and technical specifications of pumps.
This second edition cancels and replaces the first edition (ISO 5199:1986), which has been technically revised.
Annexes A, C and D form a normative part of this International Standard. Annexes B, E, F, G and H are for

Introduction
This International Standard is one of a set dealing with technical specifications of centrifugal pumps; they are
designated as Classes I, II and III. Class I comprises the most severe and Class III the least severe requirements.
The selection of the class to be used is in accordance with the technical requirements for the application for which
the pump is intended. The class chosen should be agreed between the purchaser and supplier. Furthermore,
additional safety requirements concerning the field of application should be taken into account.
However, it is not possible to standardize the class of technical requirements for centrifugal pumps for a certain
field of application, because each field of application comprises different requirements. All classes (I, II and III) can
be used in accordance to the different requirements of the pump application. So it may happen that pumps built in
accordance with Classes I, II and III may work beside one another in the one plant.
Further requirements covering specific applications or industries may be dealt with in separate standards.
Criteria for the selection of the required class of a pump for a certain application may include
— reliability,
— required operating life,
— operating conditions,
— environmental conditions, and
— local ambient conditions.
Cross-references in boldface and the checklist in annex H indicate where a decision may be required by the
purchaser, or where agreement is required between the purchaser and the manufacturer/supplier.

INTERNATIONAL STANDARD ISO 5199:2002(E)
Technical specifications for centrifugal pumps — Class II
1 Scope
1.1 This International Standard specifies the requirements for Class II centrifugal pumps of single-stage,
multistage, horizontal or vertical construction, with any drive and any installation for general application. Pumps
used in the chemical process industries (e.g. those conforming to ISO 2858) are typical of those covered by this
International Standard.
1.2 This International Standard includes design features concerned with installation, maintenance and safety for
these pumps including baseplate, couplings and auxiliary piping, but it does not specify any requirements for the
driver other than those related to its rated power output.
1.3 Where application of this International Standard has been called for and requires a specific design feature,
alternative designs may be offered which meet the intent of this International Standard provided that the alternative
is described in detail.
Pumps not complying with all the requirements of this International Standard may be offered for consideration
provided that all deviations are stated.
2 Normative references
The following normative documents contain provisions which, through reference in this text, constitute provisions of
this International Standard. For dated references, subsequent amendments to, or revisions of, any of these
publications do not apply. However, parties to agreements based on this International Standard are encouraged to
investigate the possibility of applying the most recent editions of the normative documents indicated below. For
undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC
maintain registers of currently valid International Standards.

3 Terms and definitions
For the purposes of this International Standard, the following terms and definitions apply.
3.1
operating conditions
all parameters (e.g. operating temperature, operating pressure) determined by a given application and pumped
liquid
NOTE These parameters will influence the type of construction and construction materials.
3.2
allowable operating range
range of flows or heads at the specified operating conditions of the pump supplied as limited by cavitation, heating,
vibration, noise, shaft deflection and other similar criteria
NOTE The upper and lower limits of the range are denoted by maximum and minimum continuous flow.
3.3
rated conditions
conditions (driver excluded) that define the guarantee values necessary to meet all defined operating conditions,
taking into account any necessary margins
3.4
driver rated power output
greatest continuous driver power output permitted under defined conditions
3.5
basic design pressure
pressure derived from the permitted stresses at 20 °C of the material used for the pressure-containing parts
3.6
maximum allowable working pressure
pressure for a component on the basis of materials used and on the basis of calculation rules at the specified
operating temperature
3.7
rated inlet pressure
inlet pressure of the operating conditions at the guarantee point
3.8
rated outlet pressure
outlet pressure of the pump at the guarantee point with rated flow, rated speed, rated inlet pressure and density

3.9
pressure/temperature limit
limiting pressure and temperature of a component at given design and material (see Figure 1)
3.10
corrosion allowance
that portion of the wall thickness of the parts wetted by the pumped liquid in excess of the theoretical thickness
required to withstand the pressure limits given at the most severe operating conditions
3.11
maximum allowable continuous speed
highest speed at which the manufacturer will permit continuous operation
3.12
trip speed
speed at which the independent emergency overspeed devices operate to shut down a prime mover
3.13
first critical speed
speed of rotation at which the first (lowest) lateral natural frequency of vibration of the rotating parts corresponds to
the frequency of rotation
3.14
design radial load
radial load of the pump rotor for which the bearing system is selected
3.15
maximum radial load
greatest radial load of the pump rotor resulting from operating the pump at any condition within its allowable
operating range
3.16
shaft runout
total radial deviation indicated by a device measuring the shaft position in relation to the bearing housing, as the
shaft is rotated manually in its bearings with the shaft in the horizontal position
3.17
face runout
total axial deviation indicated at the outer radial face of the shaft seal casing by a device attached to and rotated
with the shaft when the shaft is rotated manually in its bearings in the horizontal position
NOTE The radial face is that which determines the alignment of a seal component.
3.18
shaft deflection
displacement of a shaft from its geometric centre in response to the radial hydraulic forces acting on the impeller
NOTE Shaft deflection does not include shaft movement caused by tilting within the bearing clearances, bending caused
by impeller unbalance, or shaft runout.
3.19
seal flush
circulation
return of pumped liquid from high pressure area to seal cavity
NOTE This can be by external piping or internal passage and is used to remove heat generated at the seal or to maintain
positive pressure in the seal cavity or treated to improve the working environment for the seal. In some cases it may be
desirable to circulate from the seal cavity to a lower pressure area (e.g. the inlet).

the seal.
3.21
quenching
continuous or intermittent introduction of an appropriate (clean, compatible, etc.) fluid at lower than seal chamber
pressure on the atmospheric side of the main shaft seal
