This standard does not apply to fire-fighting centrifugal pumps with primer of which the only power source is directly applied manual effort.
This standard specifies the classification and general requirements for fire-fighting centrifugal pumps with priming devices with a nominal delivery rate of up to 6000 l/min.
This standard deals with significant hazards listed in clause 4, hazardous situations and events during the commis-sio-ning, operation and maintenance of fire-fighting centrifugal pumps with priming devices, used as intended and under the conditions foreseen by the manufacturer or the manufacturer's authorized representati-ve. In addition, fire-fighting centrifugal pumps with priming devices shall conform as appropriate to EN 292 for hazards not covered by this standard.
This standard does not deal with the detailed verification of general and safety requirements and/or protective measures. These are covered in prEN 1028-2 "Verification of general and safety requirements".
This standard does not deal with the technical safety requirements for the design or manufacture of drivers or of auxiliary equipment. It does not cover risks directly arising from means provided for the portability, trans-portability, and mobility of pump units during or between periods of operation, or requirements for transmission shafts linking self-propelled machinery to a pump.

0 Introduction
This European Standard is a type C standard as stated in EN 292 and EN 1070.
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are
indicated in the scope of this standard.
Where 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 in accordance with the provisions of this type C standard.
This Standard has been prepared as a harmonized standard to provide one means of conformity with essential
requirements of the Machinery Directive and associated EFTA Regulations.
While producing this standard it was assumed that:
a) only trained persons operate the machine;
b) components without specific requirements are:
1) designed in accordance with the usual engineering practice and calculation codes, including all failure
modes;
2) of sound mechanical construction;
3) of materials with adequate strength and of suitable quality;
4) of materials free of defects;
NOTE General hazards due to hydraulic and pneumatic equipment are dealt with in standards for common use such as
EN 982, EN 983.
c) harmful materials (e.g. asbestos) are not used as part of the machine;
d) components are kept in good repair and working order, so that the required characteristics remain;
e) by design of the load bearing elements, a safe operation of the machine is assured for loading, from 0 % to
100 % of the rated possibilities and during the tests;
f) to ensure the correct functioning of the equipment, the ambient temperature is maintained between -15 C (for
special conditions, -30 C; see 6.12) and 40 C;
NOTE Directly around the pump the temperature can be 20 C higher.
g) the manufacturer and the user have agreed the features of the machinery and the operating conditions;
h) the place of installation enables safe usage of the machine.

tions as well as by their shaft ends.
This standard applies for fire-fighting centrifugal pumps with priming devices for use under ambient temperatures
between -15 C and 40 C.
NOTE For special conditions, -30 C; see 6.12.
This standard does not apply to fire-fighting centrifugal pumps with primer of which the only power source is directly
applied manual effort.
This standard specifies the classification and general requirements for fire-fighting centrifugal pumps with priming
devices with a nominal delivery rate of up to 6000 l/min.
This standard deals with significant hazards listed in clause 4, hazardous situations and events during the commissio-
ning, operation and maintenance of fire-fighting centrifugal pumps with priming devices, used as intended and under
the conditions foreseen by the manufacturer or the manufacturer's authorized representative. In addition, fire-fighting

measures. These are covered in EN 1028-2 "Verification of general and safety requirements".
This standard does not deal with the technical safety requirements for the design or manufacture of drivers or of
auxiliary equipment. It does not cover risks directly arising from means provided for the portability, transportability, and
mobility of pump units during or between periods of operation, or requirements for transmission shafts linking self-
propelled machinery to a pump. In addition, this standard does not cover:
operation subject to special rules (e. g. potentially explosive atmospheres);
hazards occuring due to decommissioning;
hazards occuring during handling;
hazards occuring when in use (e. g. on public roads).
