SE Series Between-Bearings Single-/Two-Stage Double Flow Axially Split Pumps
Applications: To be installed in main plants for hot water circulation in the heating circuit systems within a whole district.
Design: ASE series pump units consist of a centrifugal pump, an induction motor, a drive coupling, a coupling guard and a fabricated base plate.
The pump units shall be rigidly anchored to the foundation, and piping shall be rigidly connected to the pumps.
The pump are electrically driven horizontal single stage or two-stage (SE 800-100-11 and SE 1250-140-11) axially split volute casing centrifugal pumps with one or two (in case of two-stage pumps) double entry radial impellers. The stages are communicated with interstage crossover. Semicentreline casing support for accurate alignment.
The pump rotor is carried by the oil-ring or pressure lubricated plain or antifriction bearings with oil bath.
Pump shaft sealing is by means of packed glands.
Sense of rotation of pump shaft is clockwise or counterclockwise (in case of SE 500-70-16-S and SE 800-55-11-S), if viewed from the drive side:
