This is my first post here, but I need some information.

I am working on a project where I am trying to pump a shear sensitive fluid. I was hoping to use either a progressive cavity pump or piston pump, but my flow rate is very high - 12,500 gpm. In addition, I only need 10 psig (23 ft TDH) of discharge pressure. All of the pumps I am finding won't go up this high. 5000 gpm is the highest I can find.

Am I stuck using an axial flow pump for this? Or does anyone have any other suggestions?

Thanks!

Daniel:

Why not use three of the 5,000 gpm pumps? This would provide you with a 67% online capability when one pump is out of service for maintenance or failure or whatever. Sparing a 12,500 gpm pump would be quite costly.

I'd considered that, but the big PD pumps aren't cheap, either.

The original thought behind the design was to use all the same type of pump to keep the parts (and labor) costs down. But, now I'm running into the size of pumps issue. I'm now finding out that some of the downstream pumps are even bigger, and I don't want 6 pumps on one manifold.

I may have to go back to the basic design and see if there is another way to do the same thing. I was just hoping that someone knew of a way to do this with fewer pumps.
