Overview

This document provides detailed technical specifications and performance data for a series of self-priming pumps designed for dirty water applications. The pumps are characterized by their ability to handle solids, various impeller diameters, number of blades, and operating speeds (RPM). The data includes head (H) in meters, absorbed horsepower (Hp ass.), flow rates, and solids handling capabilities.

1. Pump Types and Series

• Series: CS-S, CS-S2, CS-S3, CS-S4, CS-S6, CS-S8, CS-S10
• Types: Various models such as A17, A22, A26, A34, A45, A1655, A1722, A1831, A2116, A2337, A2414, A2507, etc.
• Configurations include BRX, TBX, and S variants.

2. Impeller Specifications

• Impeller diameters range from 108 mm to 315 mm depending on the pump model.
• Number of blades varies between 2, 3, 4, 5, and 7 blades.
• Solids handling capability ranges from 13 mm up to 76 mm diameter solids passage.

3. Performance Parameters

Performance data is provided for different RPM values, typically ranging from 1450 to 3600 RPM, with some models operating at intermediate speeds such as 2900, 3000, 3400 RPM, etc.

• Head (H): Varies widely depending on pump type, impeller size, and RPM, with values from approximately 2 meters up to over 58 meters.
• Absorbed Power (Hp ass.): Corresponds to the power required at given operating points, ranging from as low as 0.32 Hp to over 58 Hp.
• Flow Rates: Expressed in cubic meters per hour (m³/h) and liters per minute (l/1'), with ports ranging from 6 to over 60.

4. Solids Handling

The pumps are designed to handle solids of various maximum diameters, critical for dirty water applications:

• Small solids passage: 13 mm, 15 mm, 18 mm
• Medium solids passage: 28 mm, 37 mm, 38 mm, 45 mm
• Large solids passage: 50 mm, 60 mm, 76 mm

5. Operating Conditions and Recommendations

• RPM selection affects head and power consumption significantly.
• Number of impeller blades influences pump performance curves, with more blades generally increasing head and power.
• Impeller diameter selection is critical for matching required flow and head.
• Solids handling capability must be matched to the application to avoid clogging and damage.

6. Summary of Key Data Tables

The document contains multiple tabulated data sets showing relationships between:

• Number of blades vs. Head and Power at various RPMs
• Impeller diameter vs. solids handling capacity
• Flow rates vs. pump ports and RPM

These tables enable selection of the appropriate pump model and configuration based on required hydraulic performance and solids handling needs.

7. Best Practices

• Choose pump type and impeller size based on the maximum solids size expected in the fluid.
• Consider the number of blades to optimize efficiency and power consumption for the desired head and flow.
• Operate pumps within recommended RPM ranges to ensure longevity and performance.
• Verify absorbed power requirements to ensure compatibility with available power sources.

Conclusion

This technical document serves as a comprehensive reference for selecting and operating self-priming pumps for dirty water applications. It provides critical specifications on impeller design, solids handling, performance curves, and power requirements to guide engineers and technicians in pump selection and system design.
