Guides written for the person signing the purchase order, not for the person who already knows which model they want.
Reading a duty point
Flow and head define a point on a curve, and a pump that meets it on paper can still be the wrong pump.
Choosing a seal
The seal is the component that decides service life, and it is chosen by the liquid rather than by the pump.
Centrifugal or positive displacement
One accelerates the liquid, the other displaces a fixed volume, and viscosity decides which of those works.
Why NPSH matters
Cavitation is a suction side problem, and it destroys a pump that was correctly sized on the discharge side.
Matching fitting standards
DN50 and 2 inch are not the same thing, and a line with mixed standards is a maintenance problem waiting several years to appear.
What a document package should contain
On a regulated plant the paperwork is part of the equipment, and asking for it after the order is too late.
Send the duty point and we will send the model
Include the medium and its temperature, the flow rate and head or the tank volume, the connection size and standard, the material you need and the quantity and destination port.
