The performance parameters of slurry pump include: head, flow rate, speed, shaft power, pump efficiency, efficiency and NPSH.
All the above parameters are the important basis for the selection and design of slurry pump. Therefore, in the calculation, the above performance parameters are as far as possible, so that the most suitable slurry pump can be finally selected.
The slurry pump head and flow rate are the necessary parameters for model selection, which should be provided by the user or calculated through the drawings. Otherwise, the slurry pump model cannot be determined.
Clean water is the most convenient medium for pump performance test. The general slurry pump manufacturers only provide customers with clean water performance.
In general, the head indicated by the height of the liquid column is only related to the motion state of the liquid
The same pump delivers water, air, mercury and other fluids on the same numerical value.
When slurry pump transport slurry, the slurry concentration, the size of solid particles, viscosity, and other effects.
The head and efficiency of the same slurry pump will change when water and slurry are transported.
Compared with pumping clean water, pumping slurry with high concentration of coarse particles significantly reduces the pump head and efficiency
In some cases, the efficiency of the pump will be improved when the slurry pump transports fine particles.
