LPCD4

Summary

Product identification

The EBARA LPCD 4 Poles series consists of 50 Hz centrifugal pumps.

Operating limits

• Liquid Temperature: min. -10 °C, max +110 °C
• Viscosity: max 5 °E
• Maximum Ambient Temperature: +40 °C (consult OEM for details if exceeding)
• Maximum Working Pressure: 1.0 MPa

Feed water

• Type of liquid: Clean water
• Performance curves are based on measurements with clean water at 20 °C and a kinematic viscosity of ν = 1 mm²/s (1 cSt).

Product water

Performance curves are available for models LPCD4 40, LPCD4 50, LPCD4 65, LPCD4 80, and LPCD4 100.

• Tolerances are according to ISO 9906 Annex A.
• The NPSH curve is an average curve obtained under the same conditions as performance curves.
• The continuous curves indicate the recommended working range.
• Pumps should not be used at a flow rate below 10% of the best efficiency point to avoid overheating.
• Minimum Efficiency Index (MEI) values are provided for specific models, generally MEI > 0.40, with some models having MEI > 0.70.
• The efficiency of a pump with a trimmed impeller is usually lower than with a full impeller diameter. The MEI is based on the full impeller diameter.
