Pumps and pump units for liquids - Common safety requirements
This European Standard establishes the technical safety requirements for:
- constructing;
- assembling;
- erecting;
- operating;
- servicing;
a liquid pump or pump unit. It contains a list of significant hazards, which can arise with the use of a liquid pump or pump unit, and establishes the requirements and/or protective measures which will lead to a reduction of the risks.
Liquid pumps covered by this European Standard are:
- rotodynamic pumps;
- rotary positive displacement pumps;
- reciprocating displacement pumps;
supplied separately without drive (electric motor or internal combustion engine).
In general, pumps are defined as being terminated by their inlet and outlet connections as well as by their shaft ends. Pumps supplied in this form are usually called bareshaft pumps. They are 'machines' in the definition of the Machinery Directive.
The assembly of a bareshaft pump with its driver can require measures that are outside the scope of this European Standard.
Pump units are described as:
Liquid pumps together with a driver and including transmission elements, baseplates, and any auxiliary equipment.
This European Standard does not deal either with the technical safety requirements for the design or manufacture of drivers nor of auxiliary equipment. It does not set down either requirements for the risks directly arising from means provided for the portability, transportability and mobility of pump units during or between periods of their operation, nor the requirements for transmission shafts linking a tractor or other
self-propelled machinery to a pump.
This European Standard does not cover pumps and pump units for the following applications:
- pumps and pump units whose only power source is directly applied manual effort;
- pumps and pump units for medical use used in direct contact with the patient;
- pumps and pump units specially designed or put into service for nuclear purposes which, in the event of failure, can result in an emiss

- Kreiselpumpen;
- Rotierende Verdrängerpumpen;
- Oszillierende Verdrängerpumpen ;
Die für sich allein, ohne Antrieb (Elektro- oder Verbrennungsmotor) angeboten.
Im Allgemeinen werden Pumpen beschrieben durch die Ein- und Auslassstutzen sowie durch ihre Wellen¬enden. Pumpen, die auf diese Art angeboten werden, nennt man "Pumpen mit freiem Wellenende". Dies sind Maschinen gemäß der Definition der Maschinenrichtlinie.
Der Zusammenbau einer Pumpe mit freiem Wellenende mit einem Antrieb kann Maßnahmen erfordern, die außerhalb des Anwendungsbereiches dieser Europäischen Norm liegen.
Pumpenaggregate sind beschrieben durch:
Eine Flüssigkeitspumpe verbunden mit einem Antrieb, einschließlich Kraftübertragungseinheit, Grundplatte und Zusatzausrüstung.
Diese Europäische Norm behandelt weder technische Sicherheitsanforderungen für die Konstruktion oder Herstellung von Antrieben noch von Hilfseinrichtungen. Ebenso legt sie keine Anforderungen für Risiken fest, die durch Einrichtungen für das Tragen, den Transport oder die Mobilität von Pumpenaggregaten während oder zwischen den Betriebszeiten auftreten können, noch stellt sie Anforderungen an Übertragungswellen zum Anschluss an einen Traktor oder andere selbstangetriebene Maschinen für eine Pumpe.
Diese Europäische Norm gilt nicht für Pumpen oder Pumpenaggregate in den folgenden Anwendungs-bereichen:
- Pumpen und Pumpenaggregate, deren einzige Kraftquelle die unmittelbare menschlich ausgeübte Kraft ist;
- Pumpen und Pumpenaggregate für medizinische Zwecke, die in direktem Kontakt zum Patienten verwendet werden;
- Pumpen und Pumpenaggregate, die speziell für nukleare Verwendungen entwickelt oder eingesetzt werden und deren Ausfall zur Emission von Radioaktivität führen kann;
- Pumpen und Pumpenaggregate für die Verwendung auf Seeschiffen oder beweglichen Offshore-Anlagen;

Introduction
This Standard has been prepared to be a harmonized standard to provide one means of conformity with the
Essential requirements of the Machinery Directive and associated EFTA Regulations.
!This European Standard is a type C standard as stated in EN ISO 12100-1.
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are
indicated in the scope of this European Standard.
When provisions of this type C standard are different from those which are stated in type A or B standards, the
provisions of this type C standard take precedence over the provisions of the other standards for machines
that have been designed and built according to the provisions of this type C standard.
The extent to which hazards are covered is indicated in Clause 4 "List of hazards" of this European
Standard."
1 Scope
!This European Standard establishes the technical safety requirements for:
constructing;
assembling;
erecting;
operating;
servicing;
a liquid pump or pump unit. It contains a list of significant hazards, which can arise with the use of a liquid
pump or pump unit, and establishes the requirements and/or protective measures which will lead to a
reduction of the risks.
Liquid pumps covered by this European Standard are:
rotodynamic pumps;
rotary positive displacement pumps;
reciprocating displacement pumps;
supplied separately without drive (electric motor or internal combustion engine).
In general, pumps are defined as being terminated by their inlet and outlet connections as well as by their
shaft ends. Pumps supplied in this form are usually called bareshaft pumps. They are 'machines' in the
definition of the Machinery Directive.
The assembly of a bareshaft pump with its driver can require measures that are outside the scope of this
European Standard.
Pump units are described as:
4
---------------------- Page: 6 ----------------------
SIST EN 809:2000+A1:2009
EN 809:1998+A1:2009 (E)
Liquid pumps together with a driver and including transmission elements, baseplates, and any auxiliary
equipment.
This European Standard does not deal either with the technical safety requirements for the design or
manufacture of drivers nor of auxiliary equipment. It does not set down either requirements for the risks
directly arising from means provided for the portability, transportability and mobility of pump units during or
between periods of their operation, nor the requirements for transmission shafts linking a tractor or other
self-propelled machinery to a pump.
This European Standard does not cover pumps and pump units for the following applications:
pumps and pump units whose only power source is directly applied manual effort;
pumps and pump units for medical use used in direct contact with the patient;
pumps and pump units specially designed or put into service for nuclear purposes which, in the event of
failure, can result in an emission of radioactivity;
pumps and pump units for use on seagoing vessels or mobile off-shore units;
pumps and pump units specially designed for military or police purposes.
Neither does it cover pumps and pump units for hydraulic power transmission.
Specific requirements for particular features of pumps additional to the common requirements set out in this
standard can be found in other standards such as EN 1028, EN 1151, EN 1829, and in the European
Standards on submersible pump units and for liquid pumps for the use in agrifoodstuff industries.
This European Standard is not applicable to pumps and pump units which are manufactured before the date
of publication of this European Standard."

5.2 Special requirements
5.2.1 Requirements to avoid mechanical hazards
5.2.1.1 Crushing, cutting and entanglement
Exposed moving parts may create a hazard and means shall be incorporated to reduce the risk. Such means
shall include as appropriate :
barriers conforming to !EN ISO 13857" preventing contact with moving parts ;
gaps at the end-of-travel conforming to EN 349 ;
guards conforming to EN 953.
Rotating shafts with exposed keys, keyways or other projections liable to cut or catch shall be !deleted
text" guarded. Guards or permanent enclosures shall be used for rotating or reciprocating transmission
couplings or crossarms.
!Guards or casing providing the function of a guard shall be removable only with the use of a tool.
Whenever possible fixed guards or casing providing the function of a fixed guard shall be incapable of
remaining in place without their fixings.
The fixing system shall remained attached to the guard (or casing providing the function of the fixed guard) or
to the machinery when the guard is removed.
Guards which can be opened or removed to give access for adjustment or setting of controls or sensors whilst
the pump is in operation shall be secured against unintended disturbance both when open and closed and
shall not be required to be interlocked."
Unhindered access to the shaft seal where required for checking of its function and/or for its adjustment shall
be permitted.
Machined or cut parts which are exposed or likely to be exposed at any stage during the installation,
operation, or servicing of the pump or pump unit shall be treated to remove burrs, rags and sharp edges

5.2.1.2 High pressure fluid ejection
5.2.1.2.1 Shaft, piston rod or plunger sealing system
The pump shall be equipped with a shaft-, piston rod- or plunger sealing system compatible with the pumped
fluid and appropriate to the hazard likely to result from a leakage of that fluid. In assessing the compatibility
attention shall be given concerning the nature of the liquid, the pressure, and temperature. Because of the
range of characteristics of pumped liquids it is not possible to give any precise requirements to reduce the
risks.
5.2.1.2.2 Pressure containing elements
Pressure containing parts and components of a pump are to be designed to be suitable for the maximum
allowable working pressure. Movement resulting from the loss of pressure shall not create a hazard.
For reciprocating displacement pumps the maximum allowable working pressure is the highest value for the
mean pressure in the outlet section of the pump.

SIST EN 809:2000+A1:2009
EN 809:1998+A1:2009 (E)
In the case where the pump potentially can generate pressure in any part greater than the maximum allowable
working pressure of that part, the supplier shall either provide a pressure relief valve or other device to prevent
the pressure in the part exceeding 90 % of the hydrostatic test pressure (see 6.2.4), or shall advise the user of
the need to make such a provision.
5.2.1.2.3 Permitted forces and moments on pipe connections
The permitted forces and moments on pump inlet and outlet branches are to be stated by the
manufacturer/supplier. For rotodynamic pumps typical values for permissible forces and moments can be
taken from !EN ISO 5199" ; !EN ISO 9908" ; !EN ISO 9905".
For rotary positive displacement pumps typical values for permissible forces and moments can be taken from
!EN ISO 14847".
Other connections shall be capable of withstanding the forces and moments which may arise from normal
operation and from foreseeable misuse.
5.2.1.3 Ejection of transmission parts
The upper and lower limits for torque, speed, and loads, for coupling, gears, links, etc. shall not be exceeded.
5.2.1.4 Loss of stability
The pump or pump unit shall remain stable in all phases of transport, assembly, dismantling in the conditions
foreseen when tilted to an angle of 10° in any direction from its normal position. If the pump or pump unit does
not meet this requirement the manufacturer/supplier shall define the supporting devices needed to achieve
stability, or include specific reference to their need in the information for use/instruction for use. The
supporting devices shall be treated as special tools (see 5.2.8.4), and details of their use shall be provided in
the information for use/instruction for use.
When the pump is installed it shall be made stable by the use of holding down bolts or by the use of other
anchoring methods. Holding-down bolts or other anchoring methods shall be strong enough to prevent
unintended bodily movement of the equipment.
5.2.1.5 !Lifting of pumps and pump units
Lifting machinery for pumps and pump units, lifting accessories and their components shall be capable of
withstanding the stress to which they are subjected. Lifting machinery for pumps and pump units and lifting
accessories shall be designed and constructed in such a way as to withstand the overload in static tests
without permanent deformation. Strength calculations shall take into account the value of the static test
coefficient of 1.5 to guarantee an adequate level of safety.
NOTE People responsible for pump or pump unit handling on site, in addition to the manufacturer’s instructions, may
refer to ISO 15513:2000, ISO 23813:2007, ISO 23853:2004 for the necessary skills, training and qualification of people
dealing with handling devices."
5.2.2 Requirements to avoid electrical hazards
The electrical equipment of a pump unit shall satisfy the general requirements set out in
!EN 60204-1:2006". Particular features shall conform to the particular clauses of !EN 60204-12006"
as indicated in this standard.
Electrical equipment shall be selected for safe operation in the intended application when used in the specified
environment and working conditions, and on the declared characteristics and tolerances of the electrical
supply taking into account predictable malfunctions (!EN 60204-1:2006" clauses 4, 7, 8, 13, and 18).
