OPERATING INSTRUCTIONS

The pump has been designed to operate in
environments with atmospheres that are not
potentially explosive, and with filtered water
(see par. 9.7).
Other liquids can be used only upon formal approval
by the Engineering Department or Customer
Service Department.
7.1

Water temperature

The maximum permissible water temperature
is 40 °C. However, the pump can be used with
water up to a temperature of 60 °C, but only for
short periods. In this case, it is best to consult the
Technical or Customer Service Departments.
7.2

Maximum pressure and flow rate

The rated specifications stated in our catalog are the
maximum 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 or Customer
Service Departments.
7.3

Minimum operating speed

The minimum permissible speed for these types of pumps
is 300 rpm. Any rotating speed other than that mentioned
and that indicated in the performance table (see chapter 5)
must be expressly formally authorised by our Technical 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 3744-2010 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, appropriate hearing protection must be employed
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 of a type 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 via the oil dipsticks that have minimum and
maximum marks , Fig. 3.
If necessary, top up via the oil cap , 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
plug pos. , Fig. 3.
The oil check and change must be carried out as indicated in
chapter 11.
The quantity required is ~13.5 liters.
