8. PORTS AND CONNECTIONS
KEZ Series pumps (see fig. 4) are provided with:
1. 2 inlet ports “IN”, 1” Gas. The line can be connected
to either of the two inlet ports; the ones not being
used must be hermetically sealed.
2. 2 outlet ports “OUT”, Ø 1/2” Gas
3. 3 auxiliary ports, 1/4” gas; used for the pressure
gauge only.
9. PUMP INSTALLATION
9.1 Installation
The pump must be installed in a horizontal position using
the correct threaded feet M12; fasten the screws with a
torque value of 59 ft. lbs (80 Nm). The base must be per-
fectly flat and sufficiently rigid in order to avoid bending and
misalignments on the pump/transmission coupling axis due
to the torque applied during operation. The unit must not be
rigidly fixed to the pavement, but requires the use of anti-
vibration elements. For special applications, please contact
the Customer Service Department.
Replace the oil cap (red), located on the rear
crankcase cover with the oil dipstick and
check oil level. The oil dipstick must always be
accessible, even when the unit is assembled.
The pump’s chaft (PTO) must not be rigidly
connected to the motor unit. The following
transmission types are suggested:
• hydraulic by means of flange; for correct applica
tion, please contact the Customer Service
Department
• V-belt
• Cardan Joint (please respect the maximum
working angles indicated by the manufacturer)
• Flexible joint
9.2 Direction of rotation
An arrow situated on the crankcase near the shaft indi-
cates the correct direction of rotation. Standing in front of
the pump head, the direction of rotation must be a shown
in fig. 5.
9.3 Version Change
A right version pump is defined when: observing the pump
from the head side, the PTO shank is on the right side.
A left version pump is defined when: observing the pump
from the head side, the PTO shank is on the left side.
NOTE: Fig. 5 shows a right version.
The version may be changed only by special-
ized and authorized personnel by carefully fol-
lowing the instructions that follow:
1. Separate the hydraulic part from the mechan
ical part as indicated in Chapter 2, paragraph
2.2.1 of the repair manual.
2. Rotate the mechanical part by 180 0 , and repo
sition the rear crankcase cover so that the oil
dipstick is facing upwards; reposition the lifting
bracket and the related closing caps in the
upper part of the crankcase; finally, correctly
reposition the identification plate in its appro
priate seat on the crankcase.
Be sure that the lower draining holes on
the crankcase near the plungers are open,
and not closed by the plastic caps as
required for the previous version.
3. Join the hydraulic part with the mechanical
part as indicated in Chapter 2, paragraph
2.2.5 of the repair manual.
