Product catalog summary

Technical Document Summary

1. Applications
The document outlines various applications for submersible motors and pumps, including water supply from deep wells, pressure boosting, firefighting, irrigation, and mining.

2. Specifications
Key specifications include delivery up to 180 m³/h, head up to 550 m, maximum pump diameter of 198 mm, and motor power ranging from 5.5 to 150 kW. The motors are designed for a maximum immersion depth of 350 m and can handle a maximum sand content of 100 g/m³.

3. Motor Details
Motors are rewindable three-phase with water-filled winding, operating at 380-415 V, 50 Hz. They are designed for horizontal installation with a maximum of 15 starts per hour for certain models.

4. Construction Features
Components are made of stainless steel for corrosion resistance, with guide bearings and wear rings for durability. NEMA standard dimensions are followed, with optional DUPLEX stainless steel versions available.

5. Optional Features and Accessories
Optional features include different voltages, high-temperature versions, and accessories like coupling flanges, panels, cables, and splices.

6. Materials
Various stainless steel grades and materials like NBR, POM, and PTFE are used, ensuring durability and reliability.

7. Hydraulic Performance
Performance tables are provided for different series and stages, valid for liquids with a density of 1.0 Kg/dm³ and viscosity of 1 mm²/sec.

8. Dimensions and Weights
Specific dimensions and weights for each pump type and stage are detailed, with considerations for non-return valve and cable configurations.

9. Operating Characteristics
Three-phase motors operate at 380-415 V, 50 Hz, with maximum supply voltage variations of ±10%. Horizontal operation is possible with correct axial thrust management.

10. Special Versions
Special versions include motors with double cable outlets for star/delta start and series made of AISI 316 and Duplex stainless steel for high-temperature environments.

11. Control Panels
Specifications for three-phase electric panels include supply voltage, frequency, protection class, and optional accessories for enhanced monitoring and control.

12. Technical Appendix
Includes data on suction loss at various elevations, vapour pressure and density of water, flow resistance in pipelines, and conversion tables for volumetric capacity and pressure.

13. Product Selection and Company Overview
Xylect software aids in pump solution selection, and Xylem is highlighted as a global water technology company with expertise in water management.
