OPERATING INSTRUCTIONS

The SK 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 water temperature allowed is 30°C.
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.
