OK thanks for your input - I have subsequently found the original data from Flowserve at the FEED stage where they provided preliminary pump curve and data sheet detailing a suction pressure inline with the duty based on a WUC VS6 pump - So I am now asking them to look again at their design...
Yes the NGL has a high VP hence hence the NPSHA being so low. Elevation of separator for the liquid source to the pumps is at 2.07 m above grade. My thoughts were to specifiy a canned pump to provide the required NPSHA for the pump.
Rotary pumps being positive displacement would assume design...
BigInch,
The concern on high pressure came from one major supplier - Flowserve pumps, their product range is fairly extensive so I guess other manufacturers may have the same issue.
With an NPSHA of 0.34m is the rotary vane pump suitable? the reason for the VS6 selection was to increase the...
Hi, would appreciate any thoughts for a pump to handle the following duty - initial thoughts are a VS6 can pump due to the low NPSHA however the very high suction pressure is a concern from some pump suppliers that I have discussed application:-
Duty:-
Liquid: NGL (1 duty 1 on standby)
Design...
