Patented joint due to its tested longer-life parts. Many years of research, development and innovation in materials and treatments have resulted in parts with high mechanical resistance and dimensional precision. The most suitable materials and hardening processes have been tested, bearing in mind the mechanical resistance that each part specifically requires.
Including wear resistant coupling rod bush as standard prevents other more expensive parts such as shafts, coupling rods and rotors from replacing.
Minimum deformation hardening allows high precision clearance.
If two joints of the same size are compared, the patented joint has a coupling rod with 15% more section and height than the conventional joints.
The design of the body depends on the dimensioning of the joint, which directly affects on the pump´s NPSH and solids passage.
Stainless steel with induction hardening for industrial applications:
Especially designed for this range with reinforced roller bearings that neutralize the axial thrust typical of helical pumps.
