OPERATING INSTRUCTIONS

The LK pump 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 Departments.
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 catalogue are the
maximum 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 formal authorisation by our Technical or Customer
Service Departments.
7.3

Minimum rotating speed

Any rotating speed other than 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 3744-1995 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
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 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.

Check the oil level via the indicators on the sides , 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 ~14 litres.
In any case the oil must be changed at least once
a year, as it is degraded by oxidation.
For a room temperature other than between 0°C - 30°C, follow
the instructions in the following diagram, considering that oil
must have a minimum viscosity of 180 cSt.
