50ZJH High Pressure Centrifugal Pump for Coal Mining Equipment
Product DescriptionZJH High Head Slurry Pump Selction
Horizontal Slurry Pumps selection according the properities of a slurry.
The volume of slurry to be transported must be reliably determined before defining a slurry pumping application. Wiehout a clear understanding of the volumetric requirement and possible variations of demand, it would be impossible to adequately compute a pumping system solutions.
For slurry pumping, the flow rate is determined by a correlation between three factors:
1) the solids SG,
2) the tonnage of solids required to be pumped,
3) the concentration of these solids within the slurry mixture.
These three factors need to be determined prior to selecting any slurry pump. An example of how the flow rate can be calculated, using these values, is given in select pump type & materials.
Static head required
The actual vertical height (static head) over which the slurry is to be lifted must also be accurately determined prior to selectiong a pump. This is relatively easy in plant situations, where the vertical heights involved can be measured or obtained from drawings.
In the case of overland pipelines, surveying data is often required to obtain this vital information. Variations in the vertical height (normally measured from the liquid level on the intake side of the pump to the discharge point) can have a major impact on the output of any centrifugal pump.
It is therfore important that this vertical height be determined within reasonable accuracy (0.5m) prior to pump selection.
