Total Head                   H      Up to 1,200 m   (3900 feet)
Temperature                T       - 80 to + 180 Degree Celsius  (- 110 to 350 Degree F)
Discharge Pressure     P      Up to 15 MPa
  (2170 psi)
Nominal Bore              DN     from 40 to 200 mm
  (1.5 to 8 inch)

DESIGN
The pump is radial split sectional construction. In general, the discharge nozzle is upward, and the suction is rightward (viewed from driver end). The location for discharge and suction nozzle is changeable, and it is allowed to have other drain pile.

There are two varying impellers and diffusers for each size, so the efficiency area is large. The renewable ring provides a sealing function between the impeller and casing.

The axial thrust which is produced by each impeller is balanced by balancing device. For example, to balance the axial thrust by balancing drum, the residual one is stood by bearing.

The bearing is radial roller type ; residual axial thrust is balanced by centripetal thrust ball bearing, providing oil and grease lubrication. 

The shaft seal could use packing or mechanical seal, which one is chosen by order. The motor drives directly through coupling. Rotation direction is CCW viewed from driver end
