ÖNORM EN 809

This standard establishes the technical safety requirements for : constructing; assembling; erecting; operating; servicing; of 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 measures which will lead to a reduction of the risks. Liquid pumps are described as : rotodynamic pumps; rotary positive displacement pumps; reciprocating displacement pumps; supplied separately without driver. In general, pumps are defined as being terminated by their inlet and outlet connections as well as by their shaft ends. Pump units comprise the liquid pump types above together with a driver (electric motor or i.c.-engine) including transmission elements, baseplates, and any auxiliary equipment. This standard does not deal with the technical safety requirements for the design or manufacture of drivers nor of auxiliary equipment. It does not set down 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 selfpropelled machinery to a pump.
