Hydraulic Performance: Performance curves are provided in the source document, showing Head (H[m]) versus Flow Rate (Q[m³/h] and Q[l/min]) for models 90/22, 100/36, 110/44, and 130/51. Efficiency (η[%]) curves are also shown. See the official PDF for exact tabulated values and performance curves.

Performance Table: The performance table details various models (CM 90/22 M/T, CM 100/36 M/T, CM 110/44 M/T, CM 130/51 M/T) with their respective motor powers (P2 in HP/kW, P1 in HP/kW), voltage (V), current (In A), capacitor (μF), and head (m.c.a. / m.c.w.) at different flow rates (Q in l/min and m³/h). Model CM 90/22 uses a technopolymer impeller. See the official PDF for exact tabulated values.

Overall Dimensions and Weights: Dimensions (A, B, C, D, E, F, h1, h2 in mm), inlet (DNA) and outlet (DNM) connections, and weights (Kg) are provided for each model (CM 90/22, CM 100/36, CM 110/44, CM 130/51).

• Inlet/Outlet Connections: 1" for CM 90/22 and CM 100/36; 1"1/4 inlet and 1" outlet for CM 110/44 and CM 130/51. See the official PDF for exact tabulated dimensions and weights.
