Motor Flange for the Maxi Delfino 30–40 Pump

The motor flange is a structural element that connects the electric motor to the hydraulic body of the Maxi Delfino pump models 30 and 40. The precise alignment ensured by the flange is essential for the correct function of the shaft seal and the elimination of vibrations.

Cracking or deformation of the flange causes water to seep into the motor bearings or air to penetrate into the hydraulics, which leads to pump failure. The original flange corresponds to the manufacturer’s dimensions and tolerances and guarantees correct sealing of the seal.

Replacing the flange is part of an overhaul of the Maxi Delfino pump and we recommend carrying it out together with replacement of the mechanical seal and bearings for maximum reliability after the repair.
