We are in the process of replacing our water treatment plant's two (2) sludge pumps that remove the sludge from the bottom of the settlement basin.
The "lay-in" length of the original pumps is 17-1/4" (from centerline of suction side to the flange on the discharge side - see attached PDF). However, in looking at a Seepex BN 35-6LS (a new pump comparable to the exiting pump), the "lay-in" length is 36-0 15/32", which is over 2x the original "lay-in" length.
As you can see from the attached PDF, installing the new pump will require almost an entire retro-fit of the existing plumbing in the pump room. In addition, the proposed layout will also interfere with piping and valving that is below floor level.
I was hoping that someone could offer up alternate pumps and/or manufacturers that can be used in our application that have shorter "lay-in" lengths.
Thanks in advance for your thoughts and comments.
