Etanorm/Etabloc

Product catalog summary

1. Pump Types and Sizes

The document details the Etanorm and Etabloc pump series by KSB Aktiengesellschaft, covering a wide range of standardized and close-coupled centrifugal pumps. Pump sizes range from small models like 32-125.1 to large units such as 150-400. Nominal operating speeds are standardized at 1750 rpm and 3500 rpm. Each pump model is characterized by specific impeller diameters (approximately 5 mm to over 40 mm) and impeller outlet widths (from about 5 mm up to 59 mm), which are critical for hydraulic performance.

2. Performance Parameters and Curves

Comprehensive performance data are provided, including flow rates expressed in multiple units (US gallons per minute, Imperial gallons per minute, liters per second, and cubic meters per hour), total dynamic head (TDH) in meters and feet, power input in kilowatts and horsepower, and Net Positive Suction Head Required (NPSHR) values. Flow capacities vary widely, from a few liters per second to several thousand cubic meters per hour, depending on pump size. Performance curves illustrate relationships between flow, head, power consumption, and NPSHR for each pump size and speed.

3. NPSH and Cavitation Considerations

NPSHR values correspond to cavitation inception points measured with degassed water. For practical applications, it is recommended to add a safety margin of at least 0.5 meters to these values to prevent cavitation and ensure reliable pump operation.

4. Fluid Properties and Performance Adjustments

Performance data assume fluid density near 1.0 kg/dm³ and kinematic viscosity up to 20 mm²/s. When pumping fluids with different densities, performance parameters must be adjusted by multiplying by the actual fluid density to maintain accuracy.

5. Materials and Efficiency Notes

Pump construction materials include tin bronze, spheroidal graphite cast iron, and cast chrome nickel molybdenum steel. For pumps made from stainless steel grade 1.4408, efficiency values derived from performance curves should be reduced by 2 percentage points to reflect material-specific characteristics.

6. Motor Ratings and Operating Conditions

Motor nominal power ratings are valid for ambient temperatures up to 40°C and installation altitudes up to 1000 meters above sea level. Voltage and frequency specifications vary by motor power rating: motors up to 2.2 kW operate at 220-240 V or 380-420 V, while motors from 3.0 kW use 380-420 V or 660-725 V.

7. Standards and Compliance

All performance data and measurements comply with DIN 1944/III standards. The document also includes supplementary pump sizes beyond those covered by EN 733, ensuring a broad range of options for various applications.

8. Data Presentation and Multilingual Support

Data tables and performance curves are presented in multiple languages (German, English, French, Italian, Dutch, Spanish) to facilitate international use. Tables list pump sizes, impeller diameters, outlet widths, flow ranges, head, power input, and NPSHR values. Graphical curves illustrate flow versus head, power consumption, and NPSHR for each pump model and speed.

9. Critical Recommendations and Limitations

Increase NPSHR values by at least 0.5 m in practical applications to avoid cavitation risks.
Adjust performance data for fluids with densities differing from 1.0 kg/dm³ by multiplying values accordingly.
Reduce efficiency values by 2% for pumps constructed with stainless steel grade 1.4408.
Ensure motor power ratings are applied within specified ambient temperature and altitude limits to maintain performance and reliability.
Match pump selection carefully to required flow and head parameters to optimize efficiency and prevent operational issues.
