Horizontal Split Multistage Pumps (Model RR)
For boiler feed and medium pressure service
The RR includes heavy duty horizontally split casings which facilitate inspection and maintenance of the entire rotating assembly without disturbing piping or alignment. Specifically for use on higher pressure applications, the RR comes in three sizes in either a two stage or four stage arrangement. The design of volute passages and opposition of impellers greatly reduce radial and axial thrust and improve bearing and seal life.
