OPERATING INSTRUCTIONS
The VKF pump, when not ordered with the ATEX
configuration, has been designed to operate in
environments with atmospheres that are not
potentially explosive, with filtered water (see par. 9.7).
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 30
°C.
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 speed allowed for these types of pumps
is 200 rpm for non-continuous periods; any rpm other
than mentioned and shown in the performance table (see
chapter 5) must be expressly and formally authorized by the
Engineering Department or Customer Service.
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, 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.
