Technical Data Summary for Horizontal Single-Stage Pumps (SQ Series)

1. Performance Parameters

The document provides detailed performance data for horizontal single-stage pumps, specifically the SQ series. Key parameters include flow rates, head (H), power consumption (kW), and impeller sizes at various rotational speeds (1/min).

• Flow Rate Units: Cubic meters per hour (m³/h), liters per second (l/s), and liters per minute (l/min).
• Head (H): Measured in meters (m), indicating the height to which the pump can raise water.
• Power (kW): Power required by the pump at given operating points.
• Impeller Sizes: Various impeller diameters (E, F, G, H, I) are listed, affecting pump performance.
• Rotational Speeds: Data is provided for multiple speeds ranging approximately from 500 to 3000 rpm.

2. Data Organization and Interpretation

The data is tabulated showing head and power values for different impeller sizes at various flow rates and speeds. Each impeller size corresponds to a set of performance curves:

• Head decreases as flow rate increases, typical for centrifugal pumps.
• Power consumption generally increases with flow rate and impeller size.
• Higher rotational speeds yield higher heads and power requirements.

3. Operational Recommendations and Limitations

• Selection of impeller size and speed should be based on required flow and head to optimize efficiency and power consumption.
• Operating outside recommended flow or head ranges may lead to reduced efficiency or mechanical issues.
• Power ratings indicate the motor size needed for each operating condition.

4. Additional Notes

• The document includes references to specific pump models (e.g., S2Q100A, S1Q80, S3QN150) with corresponding speed and flow ranges.
• Performance data supports pump selection for various industrial and commercial applications requiring precise hydraulic characteristics.
