A lifting bracket is mounted on the pump casing for easy
installation, as per the figure below.
The bracket is sized for lifting the pump
only. Therefore it must never be used for any
additional loads.
Replace the oil filling hole closing service plug
(red) positioned on the rear casing cover. Check
the correct quantity with the oil dipstick.
The oil dipstick must always be reachable, even
when the unit is assembled.
The pump shaft (PTO) must not be rigidly
connected to the drive unit.
The following types of transmission are
recommended:
-
Hydraulics by flange, for proper application
consult with our Technical or Customer Service
Departments.
-
V-belts.
-
Universal joint (comply with the maximum
working angles recommended by the
manufacturer).
-
Flexible coupling.

From a position facing the pump head, the rotation direction
will be as in Fig. 5.

Version change
The pump version is defined as right when:
Observing the pump facing the head side, the pump shaft
must have a PTO shank on the right side.
The pump version is defined as left when:
Observing the pump facing the head side, the pump shaft
must have a PTO shank on the left side.
Note. The version shown in Fig. 5 is right.
9.4
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 suction hose must be sufficiently rigid to prevent
deformation due to the negative pressure exerted by the
action of the pump.
9.5
A positive head of at least 0.20 metres is required for the best
volumetric efficiency.
9.6
For smooth operation of the pump, the suction line must have
the following characteristics:
1. Minimum internal diameter as indicated in the graph in
2. The layout must be such as to prevent cavitation
3. Completely airtight and constructed to ensure a perfectly
4. Prevent the pump from emptying when it is stopped,
5. Do not use 3 or 4-way hydraulic fittings, adapters, swivel

The version can only be modified by trained and
authorized personnel and carefully following the
instructions below:
1. Separate the hydraulic part from the mechanical
part as indicated in chapter 2 par. 2.2.1 of the
Repair manual.
2. Turn the mechanical part 180° and reposition
the rear casing cover in such a way that the
oil dipstick is turned upward. Reposition the
lifting bracket and relative hole closing plugs
in the upper part of the casing. Finally, properly
reposition the specification label in its housing
on the casing.
Make sure that the lower casing draining
holes in correspondence with the pistons are
open and not closed from the plastic plugs
provided for the previous version.
3. Unite the hydraulic part to the mechanical
part as indicated in chapter 2 par. 2.2.5 Repair
manual.

in cavitation. Avoid 90° elbows, connections with
other piping, restrictions, reverse gradients, inverted
