Description: Relationship between the pump efficiency and the rate of flow at given operating conditions of speed and liquid; Name: characteristics of pump efficiency
Description: relationship between the total head of the pump and the rate of flow at given operating conditions /rated conditions of speed and liquid; Name: Pump efficiency curve
Description: Group of components with the same construction features and the same structure, which - due to similar manufacturing techniques - can be collated for construction approval testing and class conformity controls. They are generally allocated to a construction type. Note: in certain cases, components can be viewed from various construction type specifications as belonging to the same type and, therefore, can be collated for construction approval and class conformity controls; Name: construction form of impeller
