Mechanical / Hydraulic

The pumps are designed for operation with clean cold water, without gas content. A +0,5 m security margin on the NPSH-value is necessary. For capacities over 4 m³/h, a suction pipe G 1 1/4 (DN 32) is recommended. Tolerances are according to UNI EN ISO 9906:2012.

Performance curves and detailed performance tables (including P1 Max. power input, P2 Rated motor power output, Head H, and Flow Q for various models like MXP 202-205 and MXP 402-405, and their MXPM equivalents) are provided in the official PDF.

Dimensions and weights for various MXP and MXPM models are also tabulated in the official PDF.
