Security

2Security

The manufacturer does not accept any liability for dam-

age resulting from non-observance of the entire documen-

tation.

2.1 Intended use

• Only use the pump to pump the agreed pumped liquid

(→order data sheet).

• Adhere to the operating limits and size-dependent mini-

mum ﬂow rate.

• Avoid dry running:

Initial damage, such as destruction of plain bearings and

plastic parts, within a few seconds.

– Make sure the pump is never put into operation or oper-

ated without pumped liquid.

• Avoid cavitation:

– Fully open the suction-side ﬁtting; do not use the ﬁtting

to adjust the ﬂow rate.

– Do not open the pressure-side ﬁtting beyond the

agreed operating point.

• Avoid overheating:

– Do not operate the pump while the pressure-side ﬁtting

is closed.

– Observe the minimum ﬂow rate (→order data sheet).

• To avoid damage to the motor:

– Do not open the pressure-side ﬁtting beyond the

agreed operating point.

– Observe the number of permitted motor start-ups per

hour (→manufacturer's speciﬁcations).

• Consult the manufacturer about any other use of the pump.

Avoiding common types of misuse (examples)

• Observe the operating limits of the pump regarding oper-

ating temperature, pressure, ﬂow rate and speed (→order

data sheet).

• The power uptake of the pump increases with increasing

density of the pumped liquid. To avoid any overload for the

pump and motor, do not exceed the permissible density

(→order data sheet).

A lower density is allowed. Adapt the auxiliary systems

accordingly.

• Adhere to the limits for solids content and grit size when

pumping solids-carrying ﬂuids (→order data sheet, techni-

cal description).

• When using auxiliary operating systems:

– Ensure the ﬂushing medium is compatible with the

product medium.

– Ensure there is a permanent supply of the respective

ﬂushing medium.

2.2 General safety instructions

Take note of the following instructions before carrying out

any work.

2.2.1 Product safety

The pump has been constructed according to the latest tech-

nology and established technical safety rules. Nevertheless, a

potential risk to life and limb of the operator or to other persons

or damage to the pump and other property cannot be entirely

excluded.

• Only operate the pump if it is in perfect technical condition;

only use it as intended, staying aware of safety and risks,

and adhering to the instructions in this manual.

• Keep this manual and all other applicable documents com-

plete, legible and accessible to staff at all times.

• Refrain from any procedures that would endanger staff or

third parties.

• If a safety-relevant fault occurs, shut down the pump imme-

diately and have the fault corrected by appropriate staff.

• In addition to the entire documentation for the product,

always comply with statutory or other safety and accident-

prevention regulations as well as with the applicable stan-

dards and guidelines in the country where the pump is

operated.

2.2.2 Operator's obligations

Safety-conscious operation

• Only operate the pump if it is in perfect technical condition;

only use it as intended, staying aware of safety and risks,

and adhering to the instructions in this manual.

• Ensure the following are observed and monitored:

– Adherence to intended use,

– Statutory or other safety and accident-prevention reg-

ulations

– Safety regulations governing the handling of hazard-

ous substances

– Applicable standards and guidelines in the country

where the pump is operated

• Make protective equipment available.

Staff qualiﬁcations

• Make sure all staff assigned with work on the pump have

read and understood this manual and all other applicable

documents, especially the safety, maintenance and repair

instructions, before beginning with work.

• Organise responsibilities, who is in charge of any speciﬁc

duty and how staff is supervised.

• Makesureallworkiscarriedout by specialist technicians

only:

– Fitting, repair and maintenance work

– Work on the electrical system

• Make sure trainee staff only work on the pump under super-

vision of specialist technicians.

• Persons with implanted heart pacemakers

– Should stay away from the pump with magnetic cou-

pling and parts of the magnetic coupling

– Should not be allowed to perform any work with or on

magnetic parts

Safety devices

• Provide the following safety devices and verify their integ-

rity:

– For hot, cold and moving parts: contact protection of

the pump provided by the customer

– If electrostatic charging is possible: ﬁt appropriate

earthing.

Warranty

• Obtain the manufacturer's approval prior to carrying out

any modiﬁcations, repairs or alterations during the warranty

period.

• Only use original parts or parts that have been approved

by the manufacturer.

2.2.3 Duties of the operating staff

• Observe and keep legible all directions on the pump, e.g.

the arrow indicating the direction of rotation and the indica-

tion of ﬂuid connections.

• Do not remove the protection against accidental contact for

hot, cold and moving parts during operation.

• Use protective equipment if necessary.

• Carry out work on the pump only while the pump is not

running.

• Isolate the motor from its supply voltage and keep it locked

in that state while carrying out any ﬁtting or maintenance

work.

• Reinstall the safety devices on the pump according to reg-

ulations after completing any work on the pump.

• Persons with implanted heart pacemaker:

– Should keep a minimum distance of 1 m away from the

pump with magnetic coupling or parts of the magnetic

coupling.

– Should not be allowed to perform any work with or on

magnetic parts

2.3 Special hazards

2.3.1 Potentially explosive areas

•(→ATEX additional instructions).

2.3.2 Hazardous pumped liquids

• Observe the safety regulations for handling hazardous sub-

stances when working with hazardous pumped liquids (e.g.

hot, ﬂammable, explosive, poisonous or potentially harm-

ful).

• Use protective equipment when carrying out any work on

the pump.

2.3.3 Magnetic ﬁeld

The magnetic ﬁeld of the magnetic coupling can destroy mag-

netically sensitive products, including:

• Heart pacemakers

• ID cards with magnetic strips

• Credit cards and cheque cards

• Electrical, electronic or ﬁne mechanical equipment

(e. g. mechanical and digital watches, pocket calcula-

tors, hard drives)

work on the pump.

Secure the workplace and cordon it off if necessary:

– Ensure staff with heart pacemakers keep a minimum

distance of 1 m.

– Make sure no magnetisable metal parts are able to be

attracted by the magnetic coupling of the pump.

– Makesurenopartsofthemagneticcouplingareable

to be attracted by magnetisable metal parts.

Keep magnetically sensitive objects at least 150 mm away

from the magnetic coupling.

4.1.1 Unpacking and inspection on delivery

1. Unpack the pump/group on delivery and check it for trans-

port damage.

2. Report any transport damage to the manufacturer without

delay.

3. Dispose of packaging material according to local regula-

tions.
