DANGER
All the information contained in this section refers to hazardous situations.
In addition to the present general safety information the action-related safety
information given in the other sections must be observed.
2.1 General
▪ This operating manual contains general installation, operating and maintenance
instructions that must be observed to ensure safe operation of the system and
prevent personal injury and damage to property.
▪ Comply with all the safety instructions given in the individual sections of this
operating manual.
▪ The operating manual must be read and understood by the responsible specialist
personnel/operators prior to installation and commissioning.
▪
The contents of this operating manual must be available to the specialist
personnel at the site at all times.
▪
Information and markings attached directly to the product must always be
complied with and kept in a perfectly legible condition at all times. This applies
to, for example:
– Arrow indicating the direction of rotation
– Markings for connections
– Name plate
▪ The operator is responsible for ensuring compliance with all local regulations not
taken into account.
2.2 Intended use
▪ The pump set must only be operated within the operating limits described in the
other applicable documents.
▪ Only operate pump sets which are in perfect technical condition.
▪ Do not operate partially assembled pump sets.
▪
Only use the pump to handle the fluids described in the data sheet or product
literature of the pump model.
▪
Never operate the system without the fluid to be handled.
▪ Observe the limits for continuous duty specified in the data sheet or product
literature (Q
min
and Q
max
) (to prevent damage such as shaft fracture, bearing
failure, mechanical seal damage, etc).
▪ When untreated waste water is handled, the duty points in continuous operation
lie within 0.7 to 1.2 × Q
BEP
to minimise the risk of clogging/hardening.
▪ Avoid duty points for continuous operation at very low speeds and small flow
rates (< 0.7 × Q
BEP
).
▪ Observe the minimum flow rate and maximum flow rate indicated in the data
sheet or product literature (to prevent overheating, mechanical seal damage,
cavitation damage, bearing damage, etc.).
▪ Do not throttle the flow rate on the suction side of the system (prevention of
cavitation damage).
▪
Consult the manufacturer about any use or mode of operation not described in
the data sheet or product literature.
▪
Only use the respective impeller types in combination with the fluids described
below.
