25362 - I'm not sure I follow your comment on "concentric".
A concentric volute can still be either tangential or centerline discharge, and is a different beast altogether.
And while a concentric volute does reduce the radial load, the efficiency difference is much more pronounced...
Thanks Artisi & PUMPDESIGNER. I'm glad to hear that it is splitting hair, as the impression I had was a 2 - 9 point effect on efficiency depending on the transitions. If I had thought it was such a small difference, I wouldn't have brought it up to begin with. On the other hand, I do enjoy a...
I am sorry, PUMPDESIGNER. Maybe I'm looking at it all wrong. I hope you don't mind me "thinking out loud" here.
For a given flowrate (say 1000 gpm), the average velocities would be the same at the plane of either pump's discharge (assuming same discharge size). If an 8" pipe...
Interesting info, but I'm not sure I see it the same way. Assuming the discharge pipes are the same size at the discharge nozzle of the pump (and the same for a tangential discharge and centerline discharge), the (average) velocity should be constant at that point, for the same flowrate. The...
From a pump user's standpoint, which is preferred and why? Most chemical (read: ANSI, ISO) pumps are of centerline discharge design (the discharge flange center is in the same vertical plane as the pump's centerline). The theory, or at I've been told, is that it allows for:
(1) self-venting or...
bckemp:
what version did you try IV (regarding legacy imports)? I've only had experience with up to ver 6.3, and decided to dump it in favor of SW. In 6.3, IV seemed to dislike applying fillets and rounds more than most other programs and lofting was too simple. I tried to import my Iv files...
Not every time, but consistently, I get a message from Outlook when I start SolidWorks 2004 SP1. The message indicates that a program is trying to access my e-mail list. It doesn't happen with any other program. Anybody else seeing this?
I agree with rockguy - I fell for Inventor because of my experience with AutoCAD - bad move! I had much better results going to and from AutoCAD and MDT with SolidWorks and SolidEdge than Inventor. Do NOT make the same mistake! I'm not saying which to choose, but I gave up on Inventor and...
I think it is pathetic that none of the mid-range packages, including SW is multithreaded. Can you think of another application that needs dual procs? Outside of Adobe Premiere (video editing) and Adobe Photoshop, there is no program that is. I just saw a COSMOSFloWorks demo and even it is...
Can you get SolidWorks to display dimensions of all sketches while in the feature view? I've looked, but can't find an option to do that. As soon as you edit a sketch, the dimensions of that sketch can be viewed, but I'd like to see the dimensions of all my sketches at the same time. I...
I'm not familiar with "submersible rotodynamic" pump, but you should also ask if any modifications were done to the pump in order to make it meet performance. The test shop will likely run the test in advance of your arrival and therefore have time to make correction if needed...
jet1749 - The CPX series was started within the Dresser half of the Ingersoll-Dresser family, well before Flowserve came knocking. It was intended to be a world-wide chemical pump (for both ISO and ANSI markets), but never gained ground here in the US. Therefore, I'm guessing your outside the...
