Template for Hanging Foundation Bolts
Figure 4.2 below illustrates an alternative foundation
bolt arrangement which can be used in lieu of
standard foundation bolts. Notice the large washer
with lugs at the bottom. It should be welded to the
bolt and pipe sleeve to prevent turning. Allow a little
more than the specified threaded bolt length above
the rail of the baseplate. The excess can always be
cut off if it is not needed. A rough finish top surface is
best when applying grout.

4.3.1 Baseplate levelling
Before putting the unit on the foundation, thoroughly
clean the top of the foundation. Break off any loose
pieces of cement and roughen the top with a chisel to
afford a good hold for grout.
In case of installation over a steel structure (platform)
ensure that the top of the steel structure is cleaned
and degreased.
In order to obtain the parallelism and
flatness of pads required by API standard, baseplate
has to be properly levelled by levelling screws
provided on it and clamping the baseplate at the
foundation bolts only (For proper detailed procedure
refer to Chapter 5 para 3.9.4 of API RP 686 ).
Coupling bolting and spacer piece must
be removed from between the pump and driver half
couplings before lifting baseplate with pumping
element.
When the unit is mounted directly on
structural steel framing, it should be located directly
over as near as possible to the main building
members, beams, or walls. A soleplate should be
bolted or welded to the steel frame to guarantee the
proper surface.
When lifting baseplate with pumping
element, sling baseplate from all lifting lugs provided.
Refer to Section 2.3.1
Prepare sufficient steel plates to be placed below
each baseplate jacking screw furnished with the
baseplate. The purpose of the plate is to spread the
load of the screw without crushing the concrete
below.
