Selection of pump head
Thread Content
What factors determine the head of a centrifugal pump? ? ? Please, expert, provide details
Simply put, it is: the height that the medium needs to reach (taking the density of the medium into account) + the horizontal distance + the head loss due to the pipe fittings + a certain amount of excess volume
The parameters of the pump are determined based on the conditions at the installation site: the head is determined considering the losses present and the required pressure, the flow rate is determined according to the process requirements, and the net positive suction head available for the pump is determined based on the conditions at the inlet. What remains is the selection of the appropriate pump
Pressure required by the process, pipeline losses, vertical height
Import and export pressure requirements, vertical height difference, and pipe losses
In simple terms, it is necessary to consider by how much the liquid outlet of the storage tank is above or below the pump inlet, the height from the pump outlet pipe to the inlet of the next device, the bends and length of the pipes – that is, the equivalent length of the pipes – as well as the pressure of the next device, as well as the density and viscosity of the liquid.
First, you need an application – what is this pump used for? The head is determined by the pressure difference, in other words, the pressure you need.
