Is the selection of the water pump appropriate?
Thread Content
In the wastewater treatment process, it is known that the volume of wastewater to be treated is 25 t/h. Please check whether the performance parameters of the pumps listed in the table below are suitable Please give me your guidance. Model GD80-40: rated flow rate of 42 t/h, rated head of 40 m, rotational speed of 2900 r/min, power of 7.5 kw
No one is answering at all; almost a whole day has passed. Experienced masters, please give an answer
Where does the treated water go? It depends on the head
The treated water is discharged into the collection tank. How is head calculated?
It is necessary to consider the heights of the water pump’s inlet and outlet as well as the height of the drainage tank, taking into account the resistance losses. It is recommended to check out the book on Fluid Mechanics.
It should be reminded to LZ that if only the normal flow rate is specified in the production process, a certain margin should be considered. For high-flow, low-head pumps with ns>100, the flow margin is set at 5%, for ns
The flow rate is sufficient; it depends on where your wastewater is going How much head is needed! If it is simply discharged into a sewage tank, the head pressure will definitely be sufficient!
The flow rate is sufficient, but the client needs to specify the process conditions of the equipment to which the medium is to be delivered; only then can we provide you with some relevant references.
Your flow rate seems a bit too low. Also, it remains to be determined whether such a high head pressure is necessary; for distances that aren’t very long and heights that aren’t very high, 25 to 30 meters should be sufficient
There is enough flow capacity. As for the head pressure, consider whether it’s necessary to lift the liquid to a height of around 30 meters.
The motor power should be high enough; at least 15 kW is required. Attention must also be paid to the selection of the pump to ensure it is suitable for pumping wastewater.
You need to determine the pipeline network resistance first, and then select the pump model based on the pump’s operating curve

Since the original poster did not provide the head value, it is not possible to determine whether the water pump is suitable; the flow rate seems to be a bit high. The amount of wastewater that needs to be treated is 25 t/h, so a water pump with a flow rate of 30 t/h should suffice. I wonder if this is due to the lack of an appropriately suitable water pump
