Hello, I have application for Hydrocarbon service for Gas Plant. I know it is reciprocating Pump based on 20 gpm and 900 psid Pressure. but there is requirement imposed on it 2000 ppm to meet leak standard. i am not sure any recip will meet that one! Temp= 54 °F , SG=0.62, Viscosity =0.2 cP...

I have Crude Transfer pump application. Design duties are as below. Flow rate=25000 gpm Diff head=360 ft NPSHA=5.7 ftMax/Rated Suction Pres.: 19.31 psia Vapour Pressure= 12.5 psia Fluid= Crude SG = 0.80 Temp= 80 °F Viscosity = 1.50 Any body has suggestion which type of pump should be able to...

Txs NGLENGR and Artisi, I have do to some investigation like 007.

hi artisi, pump is Centerline mounted end suction pump oh2, with antifriction bearing single row, deep groove, radial bearings and duplex, single row, 40° angular contact thrust bearings. i wondering which are criteria to select ext. lub system?

Hello guys, Is there way to define like above certain horsepower assuming 800HP, we need the external lubrication system for bearing ?

Thank you JJ ,Big, ARtisi and CVG

may be silly question what happens if i have flat curve!

Hello guys, It came to know that head rise to shut off ratio should be between 110% to 120%. I think upper limit of 120% stands fore pump downstream sizing. but dont understand why ratio should be not be less than 110%? Regards Rotaryguy

i am in canada artisi. discharge pressure is 21.3 psig.pumping fluid is tempered cooling water which has corrosive agent KHF2 and trace of HF.any body can state manufacturer that would be great

hi guys, i am looking for pump with having corrisive fluid which contains KHF2 and traces of HF at 60 gpm, 51.3 ft head but npsha is 4.6 only as pumping fluid have vapour pressure 12.27 psia. any body can suggest pump for this application!

required head is 75 psi

i am looking for manufacturer who produce centrifugal pump at 3 gpm which can be used as dosing pump how ever i can not use metering from Milton roy pumps as system is pulsation sensitive. is any body aware of any manufacturer who produces low flow rate centrifugal pumps?

hi guy, Can anybody recommend API flush plan for fuel oil.

hi guys, i am looking pumping material normally used for Glycerol service. thank you. Rotor

thanks Ed and doct. i confusion cleared by Ed pointing Grade CW and N prefix from ASTM A494. Doct appreciate your help in order to provide more technical detail for Hastealloy. As far corrosion rate depends upon temperature and concentration of liquid. Rotor
