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.
4.1 FOUNDATION
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.
The foundation may consist of any material that will afford permanent rigid support to the full area of
the pump or driver supporting member and will absorb expected strains and shocks that may be
encountered in service.
If the pump is to be mounted on a concrete floor, foundation bolts of the specified size should be
located according to the pump’s template drawing. Each bolt should be surrounded by a pipe sleeve 2
to 3 times the diameter of the bolt. The sleeve should be held rigidly yet allowing the bolts to be
removed.
When the pump unit is mounted directly on a sump cover, it should be located directly over the
supporting beams or building walls or as close to them as possible to prevent deflection and
vibration. The pump support and motor base should be bolted and doweled to the sump cover to
retain proper alignment of piping.
4.2 EQUIPMENT NECESSARY FOR INSTALLATION
The equipment necessary for the installation is the following:
A crane, hoist or another type of lifting rig of sufficient capacity to handle the heaviest and
longest pump sub assembly.
