Running a Sundyne LMV-311 Pump in minimum flow
Running a Sundyne LMV-311 Pump in minimum flow
(OP)
Hello everybody,
If you remember, I opened a thread for using a Sundyne pump for the following application:
Fluid: Water, Flow: 10m3/hr, Suction Press: 18 barg, Discharge Press: 140 barg.
Most of the experts are on this belief that either such an application will not be feasible or Sundyne declines to provide us with such pump, personally I was on the same wavelength with you but I continued my calculation on its hydraulic as well as CFD modeling study with a given set of diffuser, impeller and a range of RPM relative to a LMV-311 @ 150 Kw drive.
Outlets-at least on the paper- show that this could work, but still there is a question in my mind:
What would be the potential disadvantages staying at minimum flow (regardless of low efficiency).
Kindly comment if you have such experience with minimum flow and maximum head.
Warmest Regards,
Pezhman.

thanks for your comments,did they finally provide you with 1900 PSI?
Could you please present its performance curve( if possible)?
Best Regards,
Pezhman.
