After thorough analysis, Hydro was able
to design a pump that addressed all of the
existing problems. Hydraulic-design
modifications were engineered to meet
stringent duty requirements with high
efficiency. Wear-ring geometry was
optimized. High-quality casting processes
ensure dimensional accuracy that was
modeled and then implemented. High-
quality surface finishes were specified and
the assembly processes optimized.
Among the technologies applied in this
innovative solution were 3-D printed sand
molds and cast-flow simulation software.
Employing these new technologies
reduced the overall cost of the finished
product and improved the delivery
window. Significantly, the plant will
realize the benefits from improved
efficiency year after year.
