Deviation between pump inlet and outlet diameters and pipeline diameter
Thread Content
For a pump with a flow rate of 25 cubic meters per hour, an inlet diameter of 65 and an outlet diameter of 50, if the recommended flow velocity is 1.5 meters per second, then the pipe diameter should be 80. In this case, the inlet diameter would be one size larger than that of the pump, while the outlet diameter would be two sizes larger. Is this appropriate? What are the consequences of mismatched pump inlet and outlet diameters with those of the pipes?
The inlet pipe must not be smaller than the pump’s inlet diameter; there are no other specific requirements. The thickness of the pipe required depends on pipe losses and investment costs
Generally, to meet the flow rate requirements, the pump outlet pipe is one size larger than the pump’s outlet diameter；

No problem, just calculate the head height
