PORTS AND CONNECTIONS
The KS series pumps (see Fig. 4) are equipped with:
2 "IN" inlet ports 2" Gas.
Line connection to any of the two ports is indifferent for
proper pump functioning. The unused ports must be
hermetically closed.
2 "OUT" outlet ports 1" 1/2 Gas.
ƒ 3 service ports 3/4" Gas; usually used for the pressure gauge
and for checking for correct priming.

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 Fig. 4.
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:
-
Flexible coupling.
-
Universal joint (comply with the maximum
working angles recommended by the
manufacturer).
-
V-belts, permissible only for versions with no
reduction unit.
-
Hydraulics by flange, for proper application
consult with our Technical or Customer Service
Departments.

Rotation direction
The direction of rotation is indicated by an arrow on the
reduction gearbox.
From a position facing the pump head, the drive rotation
direction must 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.
The version can only be modified by trained and
authorised 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. 2.2.2 of the Repair
manual.
