2 Safety

The manufacturer does not accept liability for damage
resulting from non-observance of the overall documenta-
tion.

2.1 Intended use

• Observe all provisions included in the operating instruc-
tions.
• Observe all safety instructions.
• Comply with inspection and maintenance intervals.
• Use the pump/aggregate exclusively for delivery of the
permissible media to be pumped
( General technical data, page 27).
• Observe the operating limits and the minimum flow rate
depending on size.
• Prevent dry running:
−
The mechanical seal will be damaged within only few
seconds.
−
Ensure that the pump/aggregate is only operated with
sufficient medium to be pumped, never without me-
dium to be pumped.
• Prevent cavitation:
−
Completely open the suction-side fitting and do not use
it for controlling the flow rate.
−
Do not open the pressure-side fitting beyond the
agreed operating point.
• Prevent overheating:
−
Do not operate the aggregate when the pressure-side
fitting is closed.
−
Observe the minimum flow rate
(General technical data, page 25).
• Prevent motor damage:
−
Do not open the pressure-side fitting beyond the
agreed operating point.
−
Observe the switching frequency of the aggregate.
−
The motor protection switch must not be set to a value
above nominal current.
• Any use other than the intended use must be agreed with
the manufacturer.

2.2 Potential misuse

• Observe the operating limits of the pump/aggregate con-
cerning temperature, pressure, speed, flow rate, density
and viscosity ( Operating limits, page 25).
• The higher the density of the medium to be pumped, the
higher the motor power consumption. Observe the permis-
sible density to protect the aggregate against overload.
Lower densities are permissible. In this case, adjust the
auxiliary systems accordingly.
• Refrain from delivering abrasive and solid laden liquids.
• Do not combine multiple limit values
( Operating limits, page 25).
• Prevent sudden temperature changes of the medium to be
pumped.
• Do not use in rooms where explosive gases may be present
unless the pump/aggregate has been expressly intended
for such purpose.
• Do not extract, deliver or compact explosive, inflammable,
aggressive or toxic media unless the aggregates have been
expressly intended for such purpose.
• Unauthorized opening of the pump/aggregate results in the
forfeiture of any and all claims for defects.

2.3 General safety instructions


The following provisions must be observed prior to execut-
ing any works.
2.3.1

Product safety

The pump/aggregate has been designed in accordance with
state-of-the-art technology and the generally acknowledged
rules on safety.
Yet, operation of this pump/aggregate may present a threat to
the life or physical health of the user or third parties and impair
the pump/aggregate and other property.
• Only operate the pump/aggregate in a technically flawless
condition and in accordance with the provisions, safety pre-
cautions and warnings included in these operating instruc-
tions.
• Keep these operating instructions as well as all supplied
documents complete and legible and ensure that they can
be accessed by staff at all times.
• Refrain from any operating methods which may put staff or
uninvolved third parties at risk.
• In case of defects having safety implications:
shut down the aggregate immediately and consult the per-
son in charge to rectify the defect.
• In addition to the overall documentation, all legal or other
safety and accident prevention regulations as well as all
applicable standards and guidelines of the respective coun-
try of operation must be observed.
2.3.2

Obligations of the operator

2.3.2.1 Safety-conscious working
• Only operate the aggregate in a technically flawless condi-
tion and in accordance with the provisions, safety precau-
tions and warnings included in these operating instructions.
• Ensure and verify compliance with:
−
intended use
−
legal or other safety and accident prevention regula-
tions
−
safety regulations applying to handling hazardous sub-
stances
−
applicable standards and guidelines of the respective
country of operation
• Provide for protective equipment.
2.3.2.2 Staff qualification
• Ensure that staff involved in aggregate operation has read
and understood these operating instructions and all appli-
cable documents, particularly all safety, maintenance and
servicing information, prior to starting work.
• Define clear roles and responsibilities and arrange for staff
monitoring.
• All works must only be carried out by technically qualified
staff:
−
assembly, servicing, maintenance works
−
works on electrical equipment
• Staff undergoing training must only work on the
pump/aggregate under the supervision of technically quali-
fied staff.
