7 OPERATING INSTRUCTIONS
SS71 pumps, when not ordered with the ATEX
configuration, have been designed to operate in
environments with atmospheres that are not potentially
explosive, with filtered water (see par. 9.7) and at a
maximum temperature of 85°C, with the head and all
the components in contact with the fluid made of AISI
316L, plus special high and low pressure energized seals.
SN71 pumps, when not ordered with the ATEX
configuration, have been designed to operate in
environments with atmospheres that are not potentially
explosive, with filtered water (see par. 9.7) and at a
maximum temperature of 85°C, with the head made
of AISI 420 and all the components in contact with
the fluid made of AISI 316L plus special high and low
pressure energized seals.
The SW71 and SWS71 pumps have been designed to
operate in environments with atmospheres that are
not potentially explosive, with filtered sea water (see
par. 9.7) at a maximum temperature of 85°C, with the
head and all the components in contact with the fluid
made of AISI 316L, plus special high and low pressure
energized seals.
Other liquids can be used only upon formal approval by
the Technical Office or Customer Service Department.
7.1 Water temperature
The permissible water temperature is 40°C.
However, the pump can be used with water up to a
temperature of 85°C.
In this case, it is best to consult the Technical Office
or Customer Service Department.
7.2 Maximum pressure and flow rate
The rated specifications stated in our catalog are the max.
that can be obtained by the pump. Independently of the
power used, the maximum pressure and rpm indicated on the
specification label can never be exceeded unless prior formal
authorization is given by our Technical Office or Customer
Service Department.
7.3 Minimum operating speed
The minimum speed allowed for these types of pumps
is 100 rpm for non-continuous periods; any rpm other
than mentioned and shown in the performance table (see
chapter 5) must be expressly and formally authorized by the
Engineering Department or Customer Service.
7.4 Sound emission
The sound pressure detection test was performed according
to Directive 2000/14 of the European Parliament and
Council (Machinery Directive) and EN-ISO 3744 with class 1
instrumentation.
A final detection of sound pressure must be performed on the
complete machine/system.
Should the operator be located at a distance of less than 1
meter, he will have to use appropriate hearing protection
according to current regulations.
7.5 Vibration
The detection of this value shall be carried out only with the
pump set up on the plant and at the performance declared by
the customer. Values must be in accordance with regulations.
7.6 Brands and types of oils recommended
The pump is supplied with oil suitable for room temperatures
from 0°C to 30°C.
Some types of recommended oil are indicated in the table
below, these oils have additives to increase corrosion
resistance and fatigue resistance (DIN 51517 part 2).
Alternatively you can also use Automotive Gear SAE 85W-90
oil for gearing lubrication.
