Light hydrocarbon pump selection?
Thread Content
This post was last edited by FLYTOINTER on 2010-7-11 22:50. Considering the use of a canned motor pump for transporting light hydrocarbons, with a flow rate of 5 m3/h and a head of 400 m, I would like to know what size motor is required for this application? How was it calculated? Please give me some advice, thank you
There are forums on power calculation software at: http://bbs.hcbbs.com/viewthread.php?tid=199670&highlight=%B1%C3%B9%A6%C2%CA http://bbs.hcbbs.com/viewthread.php?tid=372191&highlight=%B1%C3%B9%A6%C2%CA http://bbs.hcbbs.com/viewthread.php?tid=181217&highlight=%B1%C3%B9%A6%C2%CA Why use a canned motor pump? Can’t it be a multi-stage centrifugal pump with a mechanical seal? If you are looking for a multi-stage centrifugal pump with mechanical seals, feel free to contact me! :)
Thank you very much for your help. Our company usually uses shielded pumps for transporting light hydrocarbons. Hehe; I’ll get in touch with you again if we have the opportunity to use your company’s products
When transporting light hydrocarbons, the net positive suction head of the pump must be taken into consideration; for a head of 400 meters, a multi-stage pump should be used, and vertical sac pump is recommended
The original poster is asking for a pump with a head of 400 meters and a flow rate of 5 units – these are quite challenging parameters for ordinary centrifugal pumps, and even more difficult to achieve with canned pumps. I hope it will be possible to buy such a pump, haha. As for power, it can be calculated by multiplying flow rate by head by 1/360, and then dividing by efficiency. It is estimated that the efficiency of this pump will not exceed 20%, so the motor power must be at least 35 kW or more
Shielded pumps are commonly used for light hydrocarbons; if the head required is 400 meters, multi-stage pumps may need to be considered. The flow rate is 5 cubic meters; the specific power calculation has been provided on the 2nd floor.
