4.1 Location

The pump should be located to allow room for
access, ventilation, maintenance and inspection with
ample headroom for lifting and should be as close as
practicable to the supply of liquid to be pumped.
Refer to the general arrangement drawing for the
pump set.

4.2 Part assemblies

The supply of motors and baseplates are optional.
As a result, it is the responsibility of the installer to
ensure that the motor is assembled to the pump
and aligned (if necessary) as detailed in section 4.5
and 4.8.

4.3 Foundation

A pump should be located near the

supply of liquid and have adequate space for
operation, maintenance, and inspection. Baseplate
mounted pumps are normally placed on a concrete
foundation, which has been poured on a solid
footing. The foundation must be able to absorb any
vibration and to form a permanent, rigid support for
the pumping unit.

a) Prepare site - Inspect foundation for dirt, oil,

chips, water, etc. and remove any
contaminants.

b) Install mounting bolts using hole pattern

determined by baseplate size. Sleeve-type and
J-type bolts are commonly used to allow
movement for final bolt adjustment. Follow best
company standards and practices.

c) If not supplied, guarding shall be fitted as

necessary to meet the requirements of ISO
12100 and EN953.


4.3.1 Protection of openings and threads
When the pump is shipped, all openings are
covered. This protection/covering should not be
removed until installation. If, for any reason, the
pump is removed from service, this protection
should be reinstalled.

4.3.2 Rigid baseplates - overview
The function of a baseplate is to provide a rigid
foundation under a pump and its driver that
maintains alignment between the two. Baseplates
may be generally classified into two types:

Foundation-mounted, grouted design (Figure 4-1)

Stilt mounted, or free standing. (Figure 4-2.)

Figure 4-1


Figure 4-2

Baseplates intended for grouted installation are
designed to use the grout as a stiffening member.

Stilt mounted baseplates, on the other hand, are
designed to provide their own rigidity. Therefore
the designs of the two baseplates are usually
different.

Regardless of the type of baseplate used, it must
provide certain functions that ensure a reliable
installation. Three of these requirements are:

The baseplate must provide sufficient rigidity to
assure the assembly can be transported and
installed, given reasonable care in handling,
without damage. It must also be rigid enough
when properly installed to resist operating
loads.

The baseplate must provide a reasonably flat
mounting surface for the pump and driver.
Uneven surfaces will result in a soft-foot
condition that may make alignment difficult or
impossible for long couple pumps. Experience
indicates that a baseplate with a top surface
flatness of 1.25 mm/m (0.015 in./ft) across the
diagonal corners of the baseplate provides
such a mounting surface. Therefore, this is the
tolerance to which we supply our standard
baseplate. Some users may desire an even
flatter surface, which can facilitate installation
and alignment. Flowserve will supply flatter
baseplates upon request at extra cost. For
example, mounting surface flatness of 0.17
mm/m (0.002 in./ft) is offered on the Flowserve
Type E “Ten Point” baseplate in Figure 4-1.

The baseplate must be designed to allow the
user to final field align the pump and driver to
within their own particular standards and to
compensate for any pump or driver movement
that occurred during handling. Normal industry
practice is to achieve final alignment by moving
the motor to match the pump. Flowserve
