OPERATING INSTRUCTIONS

The KF50M pump has been designed and developed
to operate in environments with atmospheres that
are not potentially explosive and with fluids with a
high percentage of bentonite, whose recommended
maximum value of density is equal to ~ 45 sec.
Marsh cone and at a maximum temperature of 40 °C.
Other liquids can be used only upon formal approval
by the Engineering Department or Customer
Service Department.
7.1

Bentonite temperature

The maximum permissible bentonite temperature
is 30 °C. However, the pump can be used with
bentonite up to a temperature of 40 °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 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
authorisation is given by our Technical or Customer Service
Departments.
7.3

Minimum operating 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, 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 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
the table in Fig. 14 chapter 11.
The quantity required is ~ 3.8 litres.
