Servicing/Maintenance

7.1

Safety regulations

The operator ensures that all maintenance, inspection and installation work is
performed by authorised, qualified specialist personnel who are thoroughly familiar
with the manual.

DANGER

Sparks produced during maintenance work

Explosion hazard!

▷

Always perform maintenance work on explosion-proof pump sets outside
potentially explosive atmospheres.

WARNING

Pump set started up inadvertently

Risk of injury by moving parts!

▷

Make sure that the pump set cannot be started up accidentally.

▷

Always make sure the electrical connections are disconnected before carrying
out work on the pump set.

WARNING

Fluids posing a health hazard and/or hot fluids

Risk of personal injury!

▷

Observe all relevant laws.

▷

When draining the fluid take appropriate measures to protect persons and the
environment.

▷

Decontaminate pumps which handle fluids posing a health hazard.

WARNING

Hot surface

Risk of personal injury!

▷

Allow the pump set to cool down to ambient temperature.

WARNING

Improper lifting/moving of heavy assemblies or components

Personal injury and damage to property!

▷

Use suitable transport devices, hoisting equipment and lifting tackle to move
heavy assemblies or components.

NOTE

Special regulations apply to repair work on explosion-proof pump sets. Modification or

alteration of the pump set may affect explosion protection and are only permitted after

consultation with the manufacturer.

A regular maintenance schedule will help avoid expensive repairs and contribute to
trouble-free, reliable operation of the pump (set) with a minimum of maintenance
expenditure and work.

NOTE

All maintenance, service and installation work can be carried out by KSB Service. Find

your contact in the attached "Addresses" booklet or on the Internet at

".

Never use force when dismantling and reassembling the pump set.
