- WARRANTY: We will recognise the
warranty for our pumps if their installation
coincides with the explanations given in
the technical instructions.
- The maximum medium temperatures are
120°C, for shorter times of less than 30
min up to 140°C, minimum temperature
allowed is 15°C.
- Ambient temperatures are in dependence
of medium temperature:
- AT = 30°C MT = 120°C
- AT = 40°C MT = 110°C
- AT = 50°C MT = 100°C
- AT = 60°C MT = 90°C
- AT = 65°C MT = 85°C
- Maximum pressure in the system at PN6 is
6 bar, and at PN10, 10 bar.
- The pump must be properly installed, with
the shaft of the electric motor in the correct
position – a horizontal position.
- When installed, the piping system must be
in the correct position against the electric
motor – in a vertical position.
- The minimum operating pressure during
operation is dependent on the medium
temperature.
- During transport, the plant must be
completely filled with the medium and all
air bleed out.
- The electrical connection must be done by
a professional familiar with VDE and EU
regulations.
- Care must be taken that the display plate
contains precise details with technical char-
acteristics, with the electrical values upfront.

A) General
Instructions for work must always be on
hand for the installation and maintenance
personnel i.e. for supervisors and the
persons responsible for operating the pump.
During interventions on the pump, one must
be attentive to the safety at work regulations
and the warning signs:
*
GENERAL DANGER (negligence can
cause injury of user)
* DANGER OF ELECTRICITY (negligence
can cause electric shock of user)
* CAUTION (negligence can cause damage
or malfunction of pump)
- Negligence or failure to comply with
regulations and warnings can cause injury
to people, pumps, and environment. This
can lead to various accidents of electrical,
mechanical, or chemical origin, and release
of hazardous and noxious substances.
- Personnel for operational or maintenance
work with pumps (placement, assembly,
balancing, connection to an electrical
line, connection to the piping system)
must be qualified and trained for work
with pumps. Supervision and coordination
must be handled by an expert, who will
be able to solve problems and instruct the
appropriate maintenance services. For
major problems, please contact the pump
manufacturer directly.
Danger of burns! With devices pumping
hot medium, attention should be paid that
personnel do not come into contact with
hot upper surfaces of the pump.
B) Warning for maintenance services:
- All dismantled parts during intervention on
the pump must be guarded from contact.
- Removing protective parts from the
machine during operation is prohibited.
- If the medium leaks from the system, an
intervention should carried out without
threatening human health or endangering
the environment.
- Electrical connections and maintenance
must be carried out according to standards
and legislation including the safety at work
regulations.
C) Warnings for operating, maintenance,
and assembly personnel:
- The operating supervisor must ensure
that qualified personnel and experts for
each type of connection works carry out
assembly and maintenance works, and
