• CS-P Series: Multi-stage centrifugal pumps featuring primary and secondary impellers with diameters from about 152 mm to 419 mm, and port sizes typically between 50 mm and 150 mm. Models include CS-P65224ERS, CS-P453CBRX, CS-P802 series, CS-P100 series, and others.

2. Impeller and Port Specifications

• Impeller diameters vary widely by model and series, influencing flow capacity and head. Single-stage pumps range from 155 mm to 475 mm, while multi-stage pumps have primary impellers from 210 mm to 419 mm and secondary impellers around 205 mm to 330 mm.
• Impeller opening sizes typically range from 5 mm to 16 mm, affecting flow characteristics and pump performance.
• Port sizes (DNa, DNm) vary from 50 mm up to 650 mm, designed to match piping systems and flow requirements.

3. Performance Parameters

• Flow Rates: Cover a broad spectrum from approximately 9 m³/h (150 l/min) up to over 110,000 l/min depending on pump size and model.
• Head (H): Hydraulic head ranges from about 1.6 meters to over 306 meters, depending on pump type, impeller size, and operating speed.
• Power Absorbed (Hp): Power consumption varies from less than 1 Hp for small pumps to over 490 Hp for large, high-capacity models.
• Rotational Speeds (RPM): Operating speeds range from 1100 RPM up to 14,000 RPM, tailored to engine or motor compatibility and pump design.

4. Performance Data Presentation

• Extensive tabulated data and performance curves relate flow rate, head, power absorbed, and RPM for each pump model.
• Data enables precise pump selection based on required hydraulic conditions and power availability.
• Performance curves show typical centrifugal pump behavior: head decreases as flow increases, while power absorbed generally rises with flow and head.

5. Construction and Design Features

• Single-stage pumps feature bare shaft designs compatible with diesel, gasoline engines, and electric motors.
• Multi-stage pumps incorporate multiple impellers in series to achieve higher heads at moderate flow rates.
• Standardized impeller openings and port sizes facilitate maintenance, interchangeability, and system integration.

6. Applications and Usage Recommendations

• Suitable for industrial applications requiring centrifugal pumping driven by diesel, gasoline engines, or electric motors.
• Select pump type and impeller size based on required flow rate and head to optimize efficiency and power consumption.
• Match operating RPM with engine or motor capabilities to ensure proper pump performance and longevity.
• Verify port sizes for compatibility with existing piping and installation constraints.
• Use power absorbed data to ensure motor or engine power ratings are sufficient to avoid overload.
• Operate pumps within recommended RPM ranges to prevent mechanical stress and maintain reliability.
• Regularly monitor power consumption to detect potential operational issues.

7. Limitations and Notes

• The document does not include detailed installation instructions, maintenance procedures, or material specifications; users should consult additional resources for comprehensive system design and operation.
• Performance varies significantly with RPM and flow rate; precise selection requires consulting specific performance curves.
• Impeller opening size critically affects flow capacity and should be matched carefully to application needs.
