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,
see the figure below.
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.
Grounding: It is necessary to fix a grounding
cable to the pump by means of the M6 stainless
steel screw and the stainless steel toothed washer
properly marked by the YELLOW label. See "ATEX
EXPLOSION PROTECTION" manual.
The pump shaft (PTO) must not be rigidly
connected to the drive unit.
The following types of transmission are
recommended:
-
Flexible coupling.
-
Cardan shaft (comply with manufacturer's Max.
recommended working angles).
-
V-belts, permissible only for versions with no
reduction unit.
In all cases the transmission must be assembled
correctly to avoid incorrect or harsh operation of
the connection parts and to prevent excessive
wear, temperature rise and/or hazardous breakages
that may create potential sources of ignition and
explosion. See "ATEX EXPLOSION PROTECTION"
manual.

Rotation direction
The pump's direction of rotation is indicated by an arrow on
the casing.
From a position facing the pump head, the drive rotation
direction must be
-
as in Fig. 6 for versions with a reduction unit
-
as in Fig. 6/a for versions with no reduction unit.

Version change
The pump version is defined as right when, observing the
pump facing the head side, the pump shaft has a PTO shank
on the RH side. The pump version is defined as left when,
observing the pump facing the head side, the pump shaft has
a PTO shank on the LH side.
Note. The versions shown in Fig. 6 and Fig. 6/a are RH.
