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
and must never be used to handle 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 direction of rotation of the PTO is indicated by an arrow
on the reduction unit cover.

observing the pump facing the manifold side, the pump shaft
must have the PTO coupling on the LH side (see Fig. 5).
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.
