The CST submersible turbine pumps are used in a variety of commercial,
municipal & industrial applications water supply is readily available
in rivers, lakes, ponds, streams or water wells. CST pumps are industry
leading from a feature & benefits standpoint. This heavy wall, vitreous
enamel lined bowl assembly uses a Francis design impeller constructed
of investment cast 304 stainless steel that provides a very broad operating
range with very high efficiency. Various sizes of ductile iron motor brackets
are available with strainer and a ductile iron discharge case is standard.
Flanged and o-ring bowls are also standard making maintenance very easy.
Threaded or flanged column assemblies are available and a wide variety
of fabricated steel discharge elbows are available. These industry exclusive
features makes this product adaptable for the power generation, municipal,
mining and oil & gas applications.
