7 OPERATING INSTRUCTIONS
SS64 pumps have been designed to operate
with filtered water (see par. 9.7) at a maximum
temperature of 85°C, with the head and all
components in contact with fluid made of AISI 316L
plus special high and low pressure energized seals.
The SN64 pumps have been designed to operate
in environments with atmospheres that are not
potentially explosive, with filtered water (see par.9.7)
and with a maximum temperature of 40°C, with AISI
420.
SW64 pumps have been designed to operate
with filtered seawater (see par. 9.7) at a maximum
temperature of 85°C, with the head and all
components in contact with fluid made of AISI 316L
plus special high and low pressure energized seals.
Other liquids can be used only upon approval by the
Technical Office or Customer Service Department.
7.1 Water temperature
The maximum permissible water temperature is
40 °C. However, it is possible to use the pump with
water up to a temperature of 85 °C. In this case, it
is best to contact our Technical Office or Customer
Service Departments.
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 rotating speed of the pump is 100 rpm, any
lower minimum speed must be expressly authorized by our
Technical Office or Customer Service Departments.
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 3744-1995 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.

Check the oil level and top up if necessary
Using the oil dipstick pos. , Fig. 3.
The correct checking of the oil level is made with the pump
not running, at room temperature. The oil change must be
made with the pump at working temperature, removing: the
oil dipstick, pos. , and then the plug pos. , Fig. 3.
The oil check and change must be carried out as indicated in
chapter 11.
The quantity required is ~ 1.9 liters.
