This document provides detailed technical data for multistage horizontal pumps, specifically models SK 100-120 and SK 100-160, manufactured by Rovatti. The data is presented primarily in tabular form, showing pump performance parameters at various operating conditions.

1. Pump Performance Specifications

The tables list key performance metrics for different pump impeller sizes (denoted by letters E, F, G, H) and rotational speeds (rpm). For each configuration, the following parameters are provided:

• Flow rate (Q): Expressed in cubic meters per hour (m³/h), liters per second (l/s), and liters per minute (l/min).
• Head (H): The height the pump can raise the fluid, given in meters (m).
• Power (N): The power consumption of the pump, given in kilowatts (kW).
• Rotational speed: Various speeds are indicated, ranging from approximately 800 to 3700 rpm depending on the model and configuration.

The data is organized by impeller size and speed, showing how head and power vary with flow rate.

2. Operating Conditions and Parameters

• The pumps operate at multiple speeds, with rpm values such as 1400, 1450, 1600, 1750, 1800, 2000, 2200, 2400, 2600, 2800, 2900, 3000, 3300, 3600, and 3700 rpm noted.
• Flow rates cover a wide range, from zero up to over 250 m³/h depending on the pump model and impeller size.
• Head values range from a few meters up to over 260 meters, indicating suitability for high-pressure applications.
• Power consumption varies accordingly, with values from under 2 kW to over 130 kW depending on operating point.

3. Pump Models and Configurations

The document includes data for multiple pump variants, identified by codes such as SR3K100-120/2, SR3K100-120/3, S4K100-120/4, SR3K100-160/2, SR3K100-160/3, and S4K100-160/5. These codes likely correspond to different stages, impeller sizes, or design versions.

4. Data Presentation and Usage

The tabular data is intended for engineers and technicians to select appropriate pump models and operating points based on required flow rate, head, and power availability. The tables enable comparison of performance across impeller sizes and speeds.

5. Key Recommendations and Considerations

• Select pump impeller size and speed to match the desired flow and head while optimizing power consumption.
• Consider the maximum power rating to ensure compatibility with available motor and power supply.
• Use the detailed performance curves to avoid operating points that may cause inefficiency or mechanical stress.
• Refer to the manufacturer’s website (www.rovatti.it) for additional technical support and product information.
