PUMP INSTALLATION

9.1

Installation

The pump must be fixed horizontally using the M16 threaded
support feet. Tighten the screws with a torque of 200 Nm.
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 brackets are mounted on the pump for easy
installation, as per the figure below.
The brackets are sized for lifting the pump only.
Therefore they 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 dipstick must always be accessible, also when
the unit is installed.
The pump shaft (PTO) must not be rigidly
OUT
connected to the drive unit.
The following types of transmission are
recommended:
IN
- Flexible coupling.
- Universal joint (comply with the maximum
working angles recommended by the
manufacturer).
- Belts, for proper application consult with our
Technical or Customer Service Departments.
