Overview

The document provides detailed technical data for multistage horizontal pumps of the SK50 series manufactured by Rovatti. It includes performance characteristics such as flow rates, head (pressure), power consumption, and impeller sizes at various rotational speeds.

Sections and Content

1. Performance Data Tables

The core of the document consists of multiple tables presenting pump performance parameters. These tables are organized by pump model variants (e.g., S1K50/2, S1K50/3, S1K50/4) and impeller sizes (denoted by letters E, F, G, H, I, L).

Each table lists:

• Flow rates in cubic meters per hour (m³/h), liters per second (l/s), and liters per minute (l/min).
• Rotational speeds in revolutions per minute (1/min), typically ranging from 1450 to 2900 rpm.
• Corresponding head values (H) in meters for each impeller size and speed.
• Power consumption (N) in kilowatts (kW) associated with each operating point.

2. Pump Operating Parameters

The data shows how head and power vary with flow rate and impeller diameter at different speeds. For example, larger impellers (E) produce higher heads and power requirements compared to smaller ones (L) at the same speed.

Speeds covered include 1450, 1750, 2000, 2200, 2600, and 2900 rpm, allowing selection based on system requirements.

3. Units and Measurement Standards

Flow rates are provided in multiple units for convenience: m³/h, l/s, and l/min. Head is measured in meters, and power in kilowatts. This facilitates integration into various engineering calculations and system designs.

4. Application and Usage Recommendations

While explicit procedural or normative guidelines are not included, the detailed performance curves enable engineers to select appropriate pump models and impeller sizes to meet specific hydraulic and power requirements.

Key Technical Insights

• Multistage horizontal pumps SK50 series cover a wide range of flow rates from approximately 100 m³/h up to over 150 m³/h depending on model and speed.
• Head values range from about 7 meters to over 130 meters, showing suitability for high-pressure applications.
• Power consumption varies from less than 1 kW for small impellers at low flow to over 17 kW for large impellers at high flow and speed.
• Impeller sizes (E to L) provide flexibility in matching pump performance to system demands.
• Multiple rotational speeds allow optimization of pump operation for efficiency and system compatibility.
