PUMP INSTALLATION

9.1

Installation

The pump must be fixed horizontally using the M16x1.5
threaded support feet. Tighten the screws with a torque of
210 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.
The unit cannot be fixed rigidly to the floor but must
interposed with vibration dampers.
For special applications contact the Technical or Customer
Service Departments.
A lifting bracket is mounted on the pump for easy installation,
as per the figure below.
Should it be necessary to disassemble it, to avoid the entrance
of dirt in the front part of the casing, close the threaded hole
with the cap provided.
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
Fig. 4
angles recommended by the manufacturer).
‑ Flexible coupling.
