8 PORTS AND CONNECTIONS
The SS71, SN71, SW71 and SWS71 series pumps (see Fig. 4) are
equipped with:
 2 "IN" inlet ports 1" 1/2 Gas.
Line connection to any of the two ports is indifferent for
proper pump functioning. The unused ports must be
hermetically closed.
 No. 2 "OUT" outlet ports 1" Gas.
ƒ No. 3 service ports 1/2" Gas; usually used for the pressure
gauge.
9 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 Department.
A lifting bracket is mounted on the pump for easy installation,
as per 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 dipstick must always be accessible, also when
the unit is installed.
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:
- Hydraulics by flange, for proper application
consult with our Technical or Customer Service
Department.
- V-belts.
- Cardan shaft (comply with manufacturer's Max.
recommended working angles).
- Flexible coupling.
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.
