OPERATING INSTRUCTIONS

The MK9M 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 Technical or Customer Service Departments.
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 in the
specification label can never be exceeded unless upon prior
formal authorization by our Technical or Customer Service
Departments.
7.3

Minimum rotating speed

The minimum permissible speed for these types of pumps is
100 rpm at the bend shaft.
Any rotating speed other than that indicated in the
performance table (see chapter 5) must be expressly
formally 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 3744-1995 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
meter, 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.
