• Nominal power in kW: e.g., 0075 (0.75 kW), 0110 (1.1 kW), 0150 (1.5 kW), 0220 (2.2 kW), 0300 (3 kW), 0400 (4 kW), 0550 (5.5 kW), 0750 (7.5 kW), 0920 (9.2 kW), 1100 (11 kW), 1500 (15 kW), 1850 (18.5 kW), 2200 (22 kW)
• Three-phase / Single-phase: T (Three-phase) / M (Single-phase)
• Number of poles: 2
• Type of starts:
  • 1 = Three-phase 230/400 V 50Hz, Single-phase 230v 50 Hz
  • 2 = Three-phase 400-690 V 50 Hz
• Motor generational code: e.g., 1

Performance Data

Detailed performance curves and tables for various CVD models (CVD 031, CVD 051, CVD 101, CVD 151, CVD 201, CVD 321, CVD 451) are available in the official PDF. These tables provide specific values for Capacity (l/s, m³/h, l/min), Total Manometric Head (m), and NPSH (m) for different pump configurations and motor powers (kW, CV). All models meet ErP M.E.I. ≥ 0.40. See the official PDF for exact tabulated values.

Dimensions and Weights

Comprehensive tables detailing overall dimensions (A, B, C, D, E, F, G, H, J, K, L, M, O, P, R, S, h, q, u, a2, b2, c2, d2, e2, f2 in mm) and weights (kg) for each specific CVD pump model are provided in the official PDF. See the official PDF for exact tabulated values.
