Hydraulic connection
Warning
Follow the connection instructions shown in the "Specifications and technical data" paragraph.
• The suction pipes must have a nominal pressure equal to 5 bar (73 psi).
• The delivery pipes must have a nominal pressure not below max. motor pump pressure.
• Do not tighten the suction and delivery fittings to a torque of more than 5 Nm (45 lbf in).
• All the pipes must be firmly fastened with clamps to the respective fittings.
For the hydraulic suction and delivery connections, refer to the following table and to Fig. 6, which represents
a generic diagram of a possible machine in which the motor pump is integrated.
The connections to suction and delivery of the motor pump must be done according to the model considering
the couplings and minimum internal pipe diameters illustrated in the following table:

CAUTION
• The suction pipes must have a minimum internal diameter as shown in the previous table and must not
present any blockages.
• The delivery pipe should have a minimum internal diameter as shown in the previous table.
• Do not use metal pipes and fittings to connect the suction and delivery.
• The pipe material must be compatible with the fluids used.
• Make sure that the pipes do not come into contact with sharp edges.
• The suction and delivery pipes must be at least 450 mm (18 in) long.
• Make sure that any residues of the materials used to seal the suction and delivery fittings do not get inside
the motor pump and/or the pipes.
• Use a 50 Mesh filter on the suction.
