UPA C 150

Summary

Product Identification

The KSB UPA series consists of submersible borehole pumps, available in various nominal sizes:

• UPA 150C: 6 inch
• UPA 200, UPA 200B: 8 inch
• UPA 250C: 10 inch
• UPA 300, UPA 350: 12 - 14 inch

The UPA 150C model designation follows the format UPA 150C - [Flow rate at best efficiency point in m³/h] / [Number of stages]. For example, UPA 150C - 16 / 9 indicates a nominal size of 150 mm, a design status 'C', a flow rate of 16 m³/h at best efficiency, and 9 stages.

Main Applications

Mechanical / Hydraulic

Design Details

• Centrifugal pump, single-stage or multistage, single-entry, ring-section design.
• Rigid connection between pump and motor.
• Type of installation: Vertical installation; Horizontal installation (depending on the number of stages).
• Impeller type: Radial or mixed flow versions.
• Bearings: Radial plain bearings. Pump bearings are lubricated by the fluid handled; motor bearings are lubricated by water fill. Axial thrust is balanced by a tilting-pad thrust bearing in the motor (lower end). An intermediate bearing is present in every stage.
• Connections: Pump screw-ended or flanged, with lift check valve or connection branch.

• Bearing carrier:
  • DN 100: CrNi steel (1.4301), CrNiMo steel (1.4404)
  • UMA 150E: CrNi steel (1.4301), CrNiMo steel (1.4571)
• Stator case:
  • DN 100: CrNi steel (1.4301), CrNiMo steel (1.4571)
  • UMA 150E: CrNi steel (1.4301), CrNiMo steel (1.4571)

  • UMA 150E: CrNi steel (1.4021) (for motors < 18.5 kW), CrNiMo steel (1.4462) (for motors ≥ 18.5 kW), CrNiMo steel (1.4462)

Connection Types (UPA 150C)

Standard pump ends vary by model variant (e.g., G 2 1/2 for UPA 150C - 16, G 3 for UPA 150C - 30, -48, -60). Possible alternative connections include:

• Threaded connections: G 3, G 4
• Flanged connections: DN 50, DN 65, DN 80

Exact dimensions and weights for specific pump/motor combinations and number of stages are provided in tables within the official PDF.
