2.2 General
This manual contains general installation, operating and maintenance instructions
that must be observed to ensure safe pump operation and prevent personal injury
and damage to property.
The safety information in all sections of this manual must be complied with.
This manual must be read and completely understood by the responsible specialist
personnel/operators prior to installation and commissioning.
The contents of this manual must be available to the specialist personnel at the site
at all times.
Information attached directly to the pump must always be complied with and be
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 in this manual.
2.3 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.
!DANGER
2 Safety
8 of 76 Amarex KRT

▪Observe the limits for continuous operation specified in the data sheet or
product literature (Qmin2) and Qmax3)) (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 1.2xQopt4) to minimize the risk of clogging/hardening.
▪Avoid duty points for continuous operation at very low speeds and small flow
rates (<0.7 x Qopt4)).
▪Observe the 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 the respective impeller types in combination with the fluids described
below.
Impeller with cutter
(impeller type S)
Suitable for the following fluids:
Faeces, domestic sewage and waste water
containing long fibers
Free-flow impeller
(impeller type F)
Suitable for the following fluids:
Fluids containing solids and stringy
material as well as fluids with entrapped

4) Best efficiency point
2 Safety
Amarex KRT 9 of 76

Prevention of foreseeable misuse
▪Observe the minimum flow velocities required to fully open the swing check
valves to prevent the reduction of pressure and risk of clogging.
(Contact the manufacturer for the required minimum flow velocities/loss
coefficients.)
▪Never exceed the permissible operating limits (pressure, temperature, etc.)
specified in the data sheet or product literature.
▪Observe all safety information and instructions in this manual.
2.4 Personnel qualification and training
All personnel involved must be fully qualified to install, operate, maintain and
inspect the machinery this manual refers to.
The responsibilities, competence and supervision of all personnel involved in
installation, operation, maintenance and inspection must be clearly defined by the
operator.
Deficits in knowledge must be rectified by means of training and instruction
provided by sufficiently trained specialist personnel. If required, the operator can
commission the manufacturer/supplier to train the personnel.
Training on the pump (set) must always be supervised by technical specialist
personnel.
2.5 Consequences and risks caused by non-compliance with these operating
instructions
▪Non-compliance with these operating instructions will lead to forfeiture of
warranty cover and of any and all rights to claims for damages.
▪Non-compliance can, for example, have the following consequences:
–Hazards to persons due to electrical, thermal, mechanical and chemical
effects and explosions
–Failure of important product functions
– Failure of prescribed maintenance and servicing practices
– Hazard to the environment due to leakage of hazardous substances
2.6 Safety awareness
In addition to the safety information contained in this manual and the intended use,
the following safety regulations shall be complied with:
▪Accident prevention, health and safety regulations
▪Explosion protection regulations
▪Safety regulations for handling hazardous substances
▪Applicable standards and laws
2.7 Safety information for the operator/user
▪The operator shall fit contact guards for hot, cold and moving parts and check
that the guards function properly.
▪Do not remove any contact guards during operation.
▪Provide the personnel with protective equipment and make sure it is used.
▪Contain leakages (e.g at the shaft seal) of hazardous fluids handled (e.g.
explosive, toxic, hot) so as to avoid any danger to persons and the environment.
Adhere to all relevant laws.
