Determination of submersible pump flow

Nanjing Forever Sewage Treatment Equipments Co., LTD. is a well-known submersible pump supplier, we are committed to providing customers with the best quality products, product quality assurance, reasonable price. Speaking of submersible pump flow, I think we will not particularly understand, here we give you a brief introduction about the determination of submersible pump flow.
1.If the submersible pump production process has been given the minimum, normal, maximum flow should be considered the maximum flow;
2.If the submersible pump production process only give the normal flow should be considered to leave a certain margin, for the large flow rate of ns> 100 low unexpected pump head flow allowance of 5% for ns> 50 low flow high head Pump flow allowance of 10%, 50 ≤ ns ≤ 100 pump flow margin also take 5%, poor quality and poor operating conditions of the pump flow margin should take 10%;
3.If the basic data only has the weight flow, should be converted into volumetric flow.
