This manual must be read and completely understood by the specialist personnel/
operators responsible 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 not tak-
en 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.

!DANGER
2 Safety
Amacan P 7 of 124

▪Never operate the pump without the fluid to be handled.
▪Observe the limits for continuous operation specified in the data sheet or prod-
uct literature (Qmin and Qmax) (to prevent damage such as shaft fracture, bearing
failure, mechanical seal damage, etc).
▪Observe the maximum flow rates indicated in the data sheet or product litera-
ture (to prevent overheating, mechanical seal damage, cavitation damage, bear-
ing damage, etc.).
▪Consult the manufacturer about any use or mode of operation not described in
the data sheet or product literature.
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 coeffi-
cients.)
▪Never exceed the permissible operating limits specified in the data sheet or prod-
uct literature regarding pressure, temperature, etc.
▪Observe all safety information and instructions in this manual.
2.4 Personnel qualification and training
All personnel involved must be fully qualified to transport, install, operate, maintain
and inspect the machinery this manual refers to.
The responsibilities, competence and supervision of all personnel involved in trans-
port, installation, operation, maintenance and inspection must be clearly defined by
the operator.
Deficits in knowledge must be rectified by means of training and instruction provi-
ded by sufficiently trained specialist personnel. If required, the operator can commis-
sion the manufacturer/supplier to train the personnel.
Training on the pump (set) must always be supervised by technical specialist person-
nel.
2.5 Consequences and risks caused by non-compliance with this manual
▪Non-compliance with this operating manual 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:

performed by authorised, qualified specialist personnel who are thoroughly fa-
miliar with the manual.
▪Only carry out work on the pump (set) during standstill of the pump.
▪The pump casing must have cooled down to ambient temperature.
▪Pump pressure must have been released and the pump must have been drained.
▪When taking the pump set out of service always adhere to the procedure descri-
bed in the manual. (⇨ Section 6.3 Page 45)
▪Decontaminate pumps which handle fluids posing a health hazard.
▪As soon as the work has been completed, re-install and/or re-activate any safety-
relevant and protective devices. Before returning the product to service, observe
all instructions on commissioning. (⇨ Section 6.1 Page 42)
2.9 Unauthorised modes of operation

Always observe the information on explosion protection given in this section when
operating an explosion-proof pump set.
Sections of the manual marked by the Ex symbol apply to explosion-proof pump sets
also when temporarily operated outside potentially explosive atmospheres.
Only pumps/pump sets marked as explosion-proof and identified as such in the data
sheet must be used in potentially explosive atmospheres.
Special conditions apply to the operation of explosion-proof pump sets in accordance
with EC Directive 94/9/EC (ATEX).
Especially adhere to the sections in this manual marked with the Ex symbol.
The explosion-proof status of the pump set is only assured if the pump set is used in
accordance with its intended use.
Never operate the pump (set) outside the limits stated in the data sheet and on the
name plate.
Prevent impermissible modes of operation at all times.

The pump is designed with an axial fluid inlet and an axial outlet. The hydraulic sys-
tem sits on the extended motor shaft. The shaft runs in common bearings.
The fluid enters the pump axially via a suction nozzle (bellmouth) (1) and is acceler-
ated outward in a rotating flow by the rotating impeller (2). The required energy is
transmitted from the electric motor (4) to the impeller (2) via the shaft (5). In the

pump bowl (3) the kinetic energy of the fluid is converted into pressure energy and
the rotational movement of the fluid flow is diverted in axial direction. The shaft pas-
sage through the casing is sealed towards the fluid with a shaft seal (10). The shaft
(5) runs in two rolling element bearings (6 and 8), which are supported by the bear-
ing housing (9) and the bearing bracket (7).
The pump is sealed by two bi-directional mechanical seals in tandem arrangement.
A lubricant reservoir in-between the seals ensures cooling and lubrication of the me-
chanical seals.
The pump sets are equipped with various sensors.
Standard
