Electrical

• Frequency: 50 Hz
• Rotation speed: Approximately 2900 min⁻¹
• Motor Power: Available in kW and HP ratings for each pump type. See the official PDF for exact tabulated values in the selection charts and performance curves.

Performance

• Tolerances: According to ISO 9906:2012 - Grade 3B.
• Test Conditions: Curves refer to effective speed of asynchronous motors at 50 Hz, 2 poles. Measurements were carried out with clean water at 20 °C and with a kinematic viscosity of 1 mm²/s (1 cSt).
• NPSH: The NPSH curve is an average curve. A safety margin of at least 1 m should be considered during pump selection.
• Operating Range: 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.
• Selection Charts: Detailed selection charts providing flow rate (l/min, m³/h) and total head (m) for various pump types and motor powers are available. See the official PDF for exact tabulated values.

Dimensions and Weight

Detailed dimensions (in mm) and weights (in kgf) for each pump model are provided in tables and sectional view drawings. See the official PDF for exact tabulated values.
