This CEN Technical Report lays down stipulations relating to installation conditions for sudden change in section or direction (elbows, tee fittings, junctions) and the most widely used accessories at the inlet and outlet of pumps (valves and fittings) in order to minimise the effect of disturbances in the flow of liquid thereby created upstream and downstream from the pump and on the operation of the pump. NOTE 1 The recommendations given in this document permit to solve a majority of the most current cases. These recommendations relate to three aspects of installation: - the fitting of the pump to pipework by convergent and divergent pipes; - in the case of elbows, tees and branching, their direction with respect to the axis of the pump; - the minimum clearances to be adhered to between a disturbing (elbow, valve, etc.) and the mounting flange of the pump.
