new pump base
(OP)
we have a sulzer t- frame pump base , i have never seen one before, the procedure for setting the anchor bolts and frame are a little odd and not what we are used to doing, usaully we install anchors, hard shims to level, torque anchors 40%, grout, then tightened anchors 100%, sulzers book has anchors in ground, base 2" off ground held up by nut on bottom side of anchor stud, there is only 3 anchor points on tee frame and base is held up by putting a washer and nut (3) on each anchor bolt, set base, tightened hold down nut against leveling nut? any thoughts on this method, why are they not wanting to pull frame down against grout? if done conventional way ,will it cause stress risers?

I would strongly warn against this method. Even if you grouted the base down and then came back and torqued the anchor nuts, this would be a bad idea. You need a suitable length of anchor stud in tension to provide the needed clamping force. We used to allow the use of nuts and washers under the base plate to level. We now require a minimum length of anchor stud, wrapped so that it will not be bonded to the grout. Your method is very much better than the one you attribute to Suzler. I prefer jack-screws rather than shims. But shims can be used with good results.
