SVI - 50 Hz

Product catalog summary

Specifications:
The SVI Series comprises submersible vertical electric pumps with IE2/IE3 motors, adhering to Regulation (EC) no. 640/2009. These pumps are suitable for industrial and civil applications, such as pumping coolants, lubricants, and condensate in various systems. They operate at 50 Hz and are available in two main groups: SVI 2, 4, 8, 16 and SVI 33, 46, 66, 92. The pumps are made of stainless steel, with the N version using AISI 316 stainless steel, and are designed for clean liquids with a kinematic viscosity up to 37mm²/sec.

Motors:
The pumps feature 2-pole motors with squirrel cage in short circuit, enclosed construction, and external ventilation. They comply with IEC 60034-30, offering IP55 protection and Class 155 (F) insulation. Available in close-coupled (E version) and standard motor (S and N versions) designs.

Hydraulic Performance:
The SVI Series delivers up to 120 m³/h and a head of up to 240 m. Operating temperatures range from -10°C to +90°C for S and N versions, and -10°C to +60°C for E versions.

Installation and Maintenance:
Typically installed vertically, with horizontal installation as an option. Mechanical seals can be replaced without removing the motor for certain models. Pumps are tested per ISO 9906 Annex A.

Optional Features and Accessories:
Options include single-phase versions, 4-pole versions, special voltages, 60 Hz frequency, and special materials for seals and gaskets. Accessories include an adapter ring for compatibility with previous models.

Materials and Standards:
Key materials include stainless steel, cast iron, silicon carbide, carbon, and elastomers like FPM and EPDM. Mechanical seals comply with EN 12756 standards.

Noise Levels:
Noise levels are measured according to ISO 1680 standards, with sound pressure levels provided for various motor sizes.

Model Combinations and Operating Characteristics:
Tables detail model combinations, power ratings, dimensions, and performance metrics. Performance data is valid for liquids with a density of 1.0 Kg/dm3 and a kinematic viscosity of 1 mm2/sec.

Installation Guidelines:
Recommendations include minimum immersion levels and distance from the bottom. The document explains Net Positive Suction Head (NPSH) and provides a formula for safe installation conditions.

Specifications and Calculations:
Discusses maximum suction head, hydraulic pressure head drop, and suction loss relative to elevation and temperature. Specific calculations for water at 15°C ensure operational efficiency.

Technical Tables:
Includes tables for friction loss, flow resistance, and conversions for volumetric capacity, pressure, head, length, and volume.

Product Selection Software - Xylect:
Xylect is a software for pump selection, offering detailed product information, performance curves, motor data, and more.

Company Overview - Xylem:
Xylem is a global water technology company providing innovative solutions for water use, conservation, and reuse, with a presence in over 150 countries.
