Fire-fighting centrifugal pumps without primer are defined as terminated by their inlet and outlet connections as well as by their shaft ends. This document applies for fire-fighting centrifugal pumps without priming devices for use under ambient temperatures between -15 °C and 40 °C. NOTE 1 For special conditions, -30 °C; see 6.11. This document does not apply to fire-fighting centrifugal pumps without primer of which the only power source is directly applied manual effort. This document does not apply to fire-fighting centrifugal pumps without primer, intended to be used as interchangeable equipment (i.e. combined by the user with another machine or vehicle acting as a driver). This document does not apply to fire-fighting centrifugal pumps without primer with a nominal delivery pressure pN above 15 bar. NOTE 2 High pressure pumps with primer are dealt with in EN 1028-1 and EN 1028-2. #This document specifies the classification and general requirements for fire-fighting centrifugal pumps without priming devices with a nominal delivery rate of up to 10 000 l/min.$ This document deals with significant hazards listed in Clause 4, hazardous situations and events during the commissioning, operation and maintenance of fire-fighting centrifugal pumps without priming devices, used as intended and under the conditions foreseen by the manufacturer. This document does not deal with the detailed verification of general and safety requirements and/or protective measures. These are covered in EN 14710-2 "Verification of general and safety requirements". This document does not deal with noise. This document does not deal with the technical safety requirements for the design or manufacture of drivers or of additional equipment intended to be fitted to inlet and outlet connections. 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 power transmission devices. In addition, this document does not cover:  hazards occurring due to decommissioning;  hazards during use due to a specific environment (e.g. traffic during use on public roads, potentially explosive atmospheres). This document does not apply to fire-fighting centrifugal pumps without primer that are manufactured before the date of publication by CEN of this document. SIST EN 14710-1:2005+A2:2009
