TenPenny, yes the 3410 has a 17" impeller.
BigInch, the pump folks are out today. We will discuss your observations when they return.
Thanks everyone for your help.

Actually, only two pumps run at a time and during the test runs one of the HSC pumps (Goulds 3410) was taken offline. The third pump was added for future increased flows only, current flows are in the 3500 to 4000 gpm range. These pumps are in parallel. The pump only deadheaded a couple of...
Here's the situation, I'm a non-mechanical project engineer on a job where we installed a surplus Goulds 3196 8x10-17 1780 rpm centrifugal pump in parallel with two split case horizontal pumps. (The other two pumps have been working fine before and after the installation of the third pump.) The...
Chances are slim to none that we have caustic leaking into the soil now. I am wondering if this was there from a spill in the past and its just taken this long to migrate to the clay particles to react?
I am pretty sure that the reaction of caustic with the clay soils is the problem. We have had similar problems at another location but it was not as widespread as this one. We have been taking data since 1999 and elevation changes have been as much as +5" at various points. I haven't been...
We have a 30+ year old caustic tank on a ringwall foundation that appeared to be sinking when compared to the containment concrete that was installed about 10 years ago. Elevation surveys over the last few years revealed that everything is actually "rising". Various points of the slab is...
