DATUM centrifugal compressors were
introduced in 1995, after three years of development by
engineers at the Turbo Products operations in
Olean, NY. The DATUM product line incorporates enhanced
engineering features which provide significant operating and
maintenance benefits. Of special interest is the fact that, in
some applications, this advanced design allows a single DATUM
compressor to compress greater flows per frame size than a
comparable existing product offering, resulting in the
capability to handle the same pressure ratio as multiple units.
The DATUM product line also offers improved rotor stability
characteristics.
 DATUM compressors are available in 14 frame sizes and they address
the ease of maintenance issue with a completely modular bundle assembly for both axially
and radially split units. The bundle assembly consists of the rotor, diaphragms and other
stationary flowpath components, bearings, seals and instrumentation - essentially
everything but the outer casing shell. This design also permits the complete assembly of
all internal components on most units in a shop environment where working conditions are
more controlled than on an operating deck.
A key feature of the DATUM product line is the standardization of components. Impeller
families and matching stationary components are designed to be scaled to all frame sizes.
The product utilizes the same impellers, diaphragms, bearings and seals in both axially
and radially split models. The same casing features are available in all frame sizes.
