OPERATING INSTRUCTIONS

The SKH 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 Engineering Department 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

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, 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 use Automotive Gear SAE 85W-90 oil for
gearing lubrication.
