Title: VERTICAL SUSPENDED CENTRIFUGAL PUMP
Abstract:
The present invention comprises a vertical suspended centrifugal pump. It is particularly useful to pump process liquids having high purity requirements or for outdoor applications in cold environments. The invention comprises a column that is an outer housing, an internal column that is an inner housing, and a shaft assembly that is partially located inside the inner housing. The outer housing encloses some part of the shaft assembly and at least partially encloses the inner housing. A wet end assembly is positioned to receive liquid through an inlet and to discharge liquid through an outlet. The present invention may be configured to include an internal barrier or buffer liquid reservoir without expensive external piping and reservoirs for pumps having two seals.
