OPERATING INSTRUCTIONS
The 70HT series pumps have been specifically
designed to operate in environments with
atmospheres that are not potentially explosive, with
filtered soft water (see par. 9.7) and at a temperature
of 85°C.
They can however work at higher temperatures
too, up to at most 105°C, under certain operating
conditions expressly authorized by our Technical or
Customer Service Departments.
Other liquids can be used only upon formal approval
by the Technical or Customer Service Departments.
To avoid any potential damage caused by the effects of
cavitation, the HT series pump supply must be forced with a
booster pump. The higher the supply pressure, the longer the
life of all the pump's hydraulics will be.
For the right ratio of minimum supply pressures and related
temperatures, refer to the graph below:
At a water temperature of 85°C, the minimum supply pressure,
measured directly on the suction line during pump operation,
must be 3 bar.
7.1
Water temperature
The maximum permissible water temperature
is 85°C. To use the pump with water at higher
temperatures, it is best to contact our Technical or
Customer Service Departments.
7.2
Maximum pressure and flow rate
The rated specifications stated in our catalogue are the max.
that can be obtained by the pump. Independently of the
power used, the maximum pressure and rpm indicated in
the specification label can never be exceeded unless upon
prior authorisation by our Technical or Customer Service
Departments.
7.3
Minimum rotating speed
The minimum rotating speed of the pump is 200 rpm, any
lower minimum speed must be expressly authorized 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
metre, 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 following
table, 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.
