DBN medium pressure stage casing pump
The DBN pumps are horizontal, radially spilt, ring section pumps with a modular design. They are suitable for pumping clean or slightly polluted, hot or cold, chemically netural or aggressive liquids. They fulfill all requirements wherever a robust pump for high pressure applications is needed, such as:
Boiler feed duties in industrial power applications up to 180℃
Condensate service in power satations and industrial plants
Feed pumps in desalination by reverse osmosis
Shower water in paper mills
High pressure water in general industry
Features and benefits
Impellers
Special suction impeller for low Net positive suction head required (NPSHr)
High quality investment cast impellers and stage casings for better efficiency
Polygon immpeller mounting allows fast and easy mounting of the impeller on the shaft, maintains straighteness of the shaft, decreases deflection and stress points and eliminates the need of standard keyed design
Mechanical design
Keyless polygon shaft torque transmission to the impeller
Split ring fixing for immpeller stack to accommodate thermal expansion
Innovative journal bearing dedign for better internal alignment and lubrication
Hydraulic balance
By means of balance drum
Product lubricated radial bearing located at Non-drive end (NDE)
Bearing unit
Double row ball radial and thrust bearing located at drive end (DE)
4 bearing units serve 6 hydraulics
Same bearing housing for both oil and grease lubrication
Increased oil sump for better heat disdipation
Constant level oiler maintains optimum oil level
Shaft sealing
Shaft sealing only required on the low pressure suction side
Separate seal chamber enables the seal type to be changed without having to replace the suction casing
Mechanical seal(Single and double),dynamic seal and gland packing are available
Shaft seal can be serviced without disassembling
Flange connection options
Different suction and discharge flange orientation (Left-up-right) allows individual customer flexibility during installation and simplifies piping design
Materials
