Design of Pumping Stations", and the references
listed in those publications. To the extent
possible the Hydraulic Institute (HI) Standards, 2000,
has been referenced as the primary reference
standard, and the minimum for manufacturers'
compliance, for the manufacture, material, design,
test, and performance specifications. The vibration
analysis often required of pumps is eliminated and a
vibration limit specified. The pumps described are
so short coupled that their resonant frequencies are
far above the source frequencies. Furthermore,
thousands of these pumps are operating worldwide.
The United States now recognizes European Common
Market (ECE) products as equal to American
manufacture; however, the American Standards quoted
are minimal. Foreign manufacturer's contacted
stated that the use of American Standards was not a
problem.
This guide specification is performance based to
comply with memorandum to USACE commands, dated 16
February 1995, stating a preference to use
performance-based standards. In the case of
pre-engineered pumps that requirement is appropriate
and agrees with the way engineering firms presently
specify these pumps. It further facilitates the
engineer's ability to use the technical expertise
available from the pump manufacturers.
Model testing is not included as an alternative for
these pumps. Manufacturers assemble and performance
test the pumps at the factory. The pumps are
shipped assembled.
Witness tests and factory visits have been limited
to one visit during the performance test and a pump
inspection at the time of the test.
Discharge piping is not covered in this guide
specification. Information about discharge piping
is contained in EM 1110-2-3105.
