Column assembly Of The Vertical Turbine Pumps
The column assembly consists of column pipe, which connects the bowl assembly to the discharge head and carries the pumped fluid to the discharge head. Houses and supports the shaft and may contain bearings. Typical column assemblies are:
a) flanged column assembly.
b) threaded column assembly: form 100 mm~355 mm (4~14 in.) sizes only.
The column supports shaft assembly, that is either
a) Open lineshaft construction utilizing the fluid being pumped to lubricate the lineshaft bearings.
Or
b) Enclosed lineshaft construction has an enclosing tube around the lineshaft and utilizes oil or other
fluid to lubricate the lineshaft bearings.
The shafts are threaded or key coupled with thrust stud design or clamp ring design.
See sectional drawings supplied with the pump for exact column assembly details as per the order. The size and configuration vary depending upon the specific order requirements and application criteria.
