4.1 Preinstallation
AF units are usually shipped completely assembled. Check all bolts and nuts on the entire unit and make
sure they are securely tightened.
If necessary install and adjust drive components per manufacturer’s recommendations
Equipment that will operate in a potentially explosive environment must be installed in accordance
with the following instructions.
All equipment being installed must be properly grounded to prevent unexpected static electric dis-
charge. If not, a static electric discharge may occur when the pump is drained and disassembled for
maintenance purposes.
4.1.1 Foundation Requirements
AF pump shall be located in a clean, dry area free from flooding. The area should provide adequate
space for operation, maintenance, inspection and repair, considering complete disassembly and handling
of equipment. The pump should have a supply of clean liquid for packing or mechanical seal lubrication.
The pump shall be positioned to provide the most efficient pipeline system.
The AF pumps covered by these instructions may be designed to hang in the piping system, furnished
with spring loaded sub-base bolts, or have a sub-base designed to be anchor bolted and grouted to the
foundation.
The foundation must be substantial enough to absorb any vibration and form a permanent, rigid support
for the pumping unit to the degree that there shall not be any adverse movement or settling over a long
period of time.
Foundations for anchor bolted and grouted sub-bases are typically concrete with anchor bolts cast in to
secure the pump.
The most commonly used foundation bolts are the sleeve-type.
