How to determine the selection of pump head
2019-01-29 05:25:35
Lift is the lift required for the process unit and is also commonly referred to as head lift. If the value of the lift is given directly in the datasheet, the rated lift of the selected pump is normally required to be 1.05 to 1.1 times the lift required by the unit. If only the inlet pressure Ps and the outlet pressure Pd are given in the datasheet, the head required for the device = (outlet pressure Pd - inlet pressure Ps) ÷ medium specific gravity Ï For media with a viscosity> 20 mm2 / s or with solid particles, Need to be converted into delivery of fresh water lift, and then determine the rated pump lift.
