   Each performance parameters of the pump exist between certain mutually dependent relationship can through to the pump to test, measure and calculate respectively parameter value, and painted curve to says, the curve is called the performance curves of pump. Every pump have certain characteristic curve, by the pump manufacturer provides. Usually in the factory the characteristic curve are also marked the performance of the recommended section, called the pump working range.
   Pump used by the curve of the actual pump of the pump device characteristic curve to determine the intersection. The selection and use of pump, should make pump working point fall in work range, so as to ensure operation efficiency and security. In addition, the same pump transportation viscosity different liquid, its characteristic curve will also change. Usually, the pump manufacturer the characteristic curve is mostly refers to the characteristics of cold water conveying clean curves.
