PUMP INSTALLATION

9.1

Installation

The pump must be fixed horizontally using the Ø16.5 drilled
support feet.
The base must be perfectly flat and rigid enough as not to
allow bending or misalignment on the pump coupling axis/
transmission due to torque transmitted during operation.
Two lifting eyebolts are mounted on the pump for easy
installation, as per the figure below.
The lifting eyebolts must not be removed.
The eyebolts are sized for lifting the pump only.
Therefore they must never be used for any
additional loads
Replace the oil filler closing plug located on the
casing with the oil filler cap.
The oil filler cap must always be reachable, even
when the unit is assembled.
The pump shaft (PTO) should not be rigidly
connected to the propulsion unit.
The following types of transmission are
recommended:
- Flexible joint.
- Cardan-shaft (comply with manufacturer's Max.
recommended working angles).
- Belts, for proper application consult with our
Technical or Customer Service Departments.
9.2

Rotation direction

The direction of rotation of the PTO is indicated by an arrow
on the reduction unit cover.
From a position facing the pump head, the rotation direction
will be as in Fig. 5.

9.3 Changing version and reduction unit
positioning
The pump version is defined as right when:
observing the pump facing the head side, the pump shaft
must have the PTO shank on the RH side.
The pump version is defined as left when:
observing the pump facing the head side, the pump shaft
must have the PTO shank on the LH side (see Fig. 5).
The version can only be changed by authorized
specialized personnel meticulously following the
instructions in the Repair manual.
In addition it is possible to position the reduction unit in 5
different positions either on the RH or LH side as per Fig. 6.
RH SIDE
The position of the reduction unit can only be
changed by authorized specialized personnel
meticulously following the instructions in the
Repair manual.
9.4

Hydraulic connections

In order to isolate the system from vibrations produced by
the pump, it is advisable to make the first section of the duct
adjacent to the pump (both suction and outlet) with flexible
piping. The consistency of the suction section must be such as
to prevent deformations caused by vacuums produced by the
pump.
