FOUNDATION
The foundation must be substantial enough to absorb
vibration. (Hydraulic Institute Standards recommends the
foundation weigh at least five [5] times the weight of the
pump unit.) It must form a permanent and rigid support for the
baseplate. This is important in maintaining the alignment of a
flexibly coupled unit.
Foundation bolts of the proper size should be embedded in the
concrete to a depth of eight (8) to twelve (12) inches and
locked with either a hook around a reinforcing bar or
alternatively, a nut and washer at the bottom. The bolts should
have a sleeve around them at least six (6) times the bolt
diameter in length and at least two (2) bolt sizes larger in I.D.
If a nut and washer are used for locking, the washer should
have an O.D. two (2) sizes larger than the sleeve. Foundation
bolts should be sized .125" less than the anchor bolt holes in
the base.
The foundation should be poured to within .75" - 1.5" of
the finished height. (See Fig. 4) Freshly poured foundations
should be allowed to cure for several days before the unit is
set in place and grouted.
