The performance parameters of the pump parts series main have flux and delivery lift. Flux per unit time is the output of liquid through the pump outlet volume, the general volume flow. Delivery lift is the unit weight of transmission fluid from the pump inlet to the outlet of the energy increment for the positive displacement pump, the energy increment is mainly reflected in the pressure can increase. It is usually replaced with a head pressure increment.
There is certain interdependence between various performance parameters of the pump parts series. You can test the pump, respectively, measured and calculated parameter values, and painted to represent the curve; the curve is called the pump characteristic curve.
