7 OPERATING INSTRUCTIONS
The LK pump, when not ordered with the ATEX
configuration, has been designed to operate in
environments with atmospheres that are not
potentially explosive, and with filtered water (see
par. 9.6).
Other liquids can be used only upon formal approval
by the Technical 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 of the crankshaft for these
types of pumps is 300 rpm; any rpm other than mentioned
and shown in the performance table (see chapter 5) must
be expressly and formally authorized by the 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 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 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 use Automotive Gear SAE 85W-90 oil for
gearing lubrication.
