2.4 Compliance with Regulations
Pertaining to Safety at Work
When operating the pump, the safety
instructions contained in this manual,
the relevant national accident prevention
regulations and any other service and safety
instructions issued by the plant operator are to
be observed.
2.5 Safety Instructions Relevant
for Operation
•
If hot or cold machine components involve
hazards, they must be guarded against
accidental contact.
•
When the pump is in operation, the open
shaft end must be covered up by shaft
protector (21A), the driven shaft side and
coupling by a bell housing and the plunger
room by cover (30).
To cover the exposed crankshaft end,
mount the shaft guard (21A) together
with the holder (21) onto the bearing
cover (14) and secure with bearing cover
screws (17).
Guards for moving parts (e.g. shaft
protector) must not be removed from the
machine while in operation.
•
Any leakage of hazardous fluids (e.g.
explosive, toxic, hot) must be drained
away to prevent risk to persons or the
environment. Statutory regulations are to be
complied with.
•
Hazards resulting from electricity are to be
prevented (e.g. see VDE Specifications
and the bylaws of the local power supply
utilities).
•
Pressure in discharge line and in pump
must be at zero before any maintenance to
the pump takes place. Close off suction line.
•
Disconnect fuses to ensure the driving
motor does not get switched on accidently.
•
Make sure all parts on the pressure side
of the unit are vented and refilled, with
pressure at zero, before starting the pump.
The following must be absolutely avoided:
cavitation, and the priming and conveyance
of any air or air/water mixture.
Cavitation and/or compression of gases
lead to uncontrollable pressure kicks
which can ruin pump and unit parts and
also be dangerous to the operator or
anyone standing nearby.
•
Before pumping other liquids -
especially inflammable, explosive and
toxic media - the pump manufacturer
must, under all circumstances,
be consulted with regard to the
resistance of the pump material. It is
the responsibility of the equipment
manufacture and/or operator to ensure
that all pertinent safety regulations are
adhered to.
2.6 Safety Instructions for
Maintenance, Inspection and
Assembly Work
It shall be the plant operator's responsibility to
ensure that all maintenance, inspection and
assembly work is performed by authorized
and qualified personnel who have adequately
familiarized themselves with the subject
matter by studying this manual in detail.
Any work on the machine shall only be
performed when it is at a standstill. Pumps
and pump units which convey hazardous
media must be decontaminated.
On completion of work, all safety and
protective facilities must be reinstalled and
made operative again. Prior to restarting
the machine, the instructions, listed under
"Operation," are to be observed.
2.7 Unauthorized Alterations and
Production of Spare Parts
Modifications to the machine can only
be made after consultation with the
manufacturer. Using spare parts and
accessories authorized by the manufacturer
is in the interest of safety. Use of other parts
may exempt the manufacturer from any
liability.
2.8 Unauthorized Modes of
Operation
The reliability of the machine delivered will
be only guaranteed if it is used in the manner
intended, in accordance with clause 1 -In
General- of this manual. The limit values
specified in the data sheet must under no
circumstances be exceeded.
