4. INSTALLATION
Correct and orderly installation/assembly is necessary for trouble-free operation of the unit.
Ruhrpumpen does not assume any liability for damage resulting from inadequate installation/assembly.
The chosen location for installation must offer enough space for maintenance activities. Ruhrpumpen
recommends consulting also API Recommended Practice 686 to ensure proper installation in your facility
and section 7.3 in the latest API 610 edition, for baseplate grouting requirements.
4.1 CONCRETE FOUNDATION PREPARATION
NOTE: The information in this section is intended as a general guideline. For further information refer to
the corresponding section in API Recommended Practices 686.
IMPORTANT: The design of foundations is not the responsibility of Ruhrpumpen. It is therefore
recommended that the customer consult a competent specialist skilled in the field of foundations, to
insure proper design/installation of the foundation.
1. Choose a solid ground location for foundation; check that the bearing capacity of the soil is at
least one third higher than both static and dynamic loads together.
2. The effects of vibrating equipment on the surrounding area should be investigated and the
isolation required for the foundation should be considered. It is important to consider that
the driver and the driven machinery must be supported from a common foundation.
All foundation materials shall be selected to prevent deterioration due to
exposure to an aggressive environment; the use of a protective coating should be
considered.
The mass of the concrete foundation should be five (5) to ten (10) times the mass
of the supported equipment.
Imaginary lines extended downward 30 degrees to either side of a vertical line
through the pump shaft should pass through the bottom of the foundation and
not the sides, as shown in the next figure.
