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.
The safety information in all sections of this manual must be complied with.
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 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 which
are 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 set to handle the fluids described in the data sheet or product
literature of the pump variant.
▪ Never operate the pump set 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
opt
to minimize the risk of clogging/hardening.
▪
Avoid duty points for continuous operation at very low speeds and small flow
rates (< 0.7 x Q
opt
).
▪ Observe the minimum flow rates and maximum flow rates 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 pump set (to prevent
cavitation damage).
▪ Consult the manufacturer about any use or mode of operation not described in
the data sheet or product literature.
▪ Only use this pump for the fluids described below.
