▪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 operation specified in the data sheet or
product literature (Qmin3) and Qmax4) ) (prevention of damage such as shaft
fracture, bearing failure, damaged mechanical seal, etc).
▪When handling untreated waste water the duty points in continuous operation
lie within 0.7 to 1.2 x Qopt5) to minimise the risk of clogging/hardening.
▪Avoid duty points for continuous operation at very low speeds and small flow
rates (<0.7 x Qopt5) ).
▪Observe the information on the maximum flow rates provided in the data sheet
or technical product literature (prevention of overheating damage, cavitation
damage, bearing damage, etc).
▪Do not throttle the flow rate on the suction side of the system (prevention of
cavitation damage).
▪For any operating modes which are not specified in the data sheet or product
literature, contact the manufacturer.
▪Only use impeller types designed for the fluid handled, as described below.
Impeller with cutter
(impeller type S)
Suitable for the following fluids:
Faeces, domestic sewage and waste water
containing long fibres
Free-flow impeller
(impeller type F)
Suitable for the following fluids:
Fluids containing solids and stringy
material as well as fluids with entrapped
air or gas
Open, diagonal single
vane impeller
(impeller type D)
Suitable for the following fluids:
Waste water with solid substances and
long fibres
Prevention of foreseeable misuse
▪Observe the minimum flow velocities for fully open 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 application limits specified in the data sheet and in
the product literature regarding pressure, temperature, etc.
▪Observe all safety notes and instructions in this manual.

other parts can invalidate any liability of the manufacturer for consequential
damage.
▪The operator ensures that all maintenance, inspection and installation work is
performed by authorised, qualified specialist personnel who are thoroughly
familiar with the manual.
▪Carry out work on the pump (set) during standstill only.
▪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
described in the manual.
▪Decontaminate pumps which handle fluids posing a health hazard.
▪As soon as the work is 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 32)
2.9 Unauthorised modes of operation
Never operate the pump (set) outside the limits stated in the data sheet and in this
manual.
The warranty relating to the operating reliability and safety of the supplied pump
(set) is only valid if the equipment is used in accordance with its intended use.
2.10 Explosion protection
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).
When operating explosion-proof pump sets, especially adhere to the additional
requirements marked by 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.
2.10.1 Repair
Special regulations apply to repair work on explosion-proof pumps. Modifications or
alteration of the pump set may affect explosion protection and are only permitted
after consultation with the manufacturer.
Repair work at the flameproof joints must only be performed in accordance with the
manufacturer's instructions. Repair to the values in tables 1 and 2 of EN 60079-1 is
not permitted.

3.3 Return to supplier
1. Drain the pump as per operating instructions.
2. Always flush and clean the pump, particularly if it has been used for handling
noxious, explosive, hot or other hazardous fluids.
3. If the fluids handled by the pump leave residues which might lead to corrosion
damage when coming into contact with atmospheric humidity, or which might
ignite when coming into contact with oxygen, the pump set must also be
neutralised, and anhydrous inert gas must be blown through the pump for
drying purposes.
4. Always complete and enclose a certificate of decontamination when returning
the pump (set). (⇨ Section 11 Page 64)
It is imperative to indicate any safety and decontamination measures taken.

The pump is designed with an axial fluid inlet and a radial outlet. The hydraulic
system sits on the extended motor shaft. The shaft runs in common bearings.
The fluid enters the pump axially via a suction nozzle (5) and is accelerated outward
in a cylindrical flow by the rotating impeller (7). The flow profile of the pump casing
converts the kinetic energy of the fluid into pressure energy. The fluid is pumped to
the discharge nozzle (6), where it leaves the pump. At the rear side of the impeller,
the shaft (1) enters the casing via the discharge cover (4). The shaft passage through
the cover is sealed towards the atmosphere with a shaft seal (8). The shaft runs in
rolling element bearings (9 and 10), which are supported by a bearing bracket (2)
linked with the pump casing and/or discharge cover.
The pump is sealed by two bi-rotational mechanical seals in tandem arrangement.
A lubricant reservoir in-between the seal elements ensures cooling and lubrication of
the mechanical seals.

5 Installation at Site
5.1 Safety regulations
DANGER
Improper installation in potentially explosive atmospheres
Explosion hazard!
Damage to the pump set!
▷Comply with the applicable local explosion protection regulations.
▷Observe the information given in the data sheet and on the name plate of the
pump set.
DANGER
Persons in the tank during pump operation
Electric shock!
▷Never start up the pump set when there are persons in the tank.
5.2 Checking the site before installation
5.2.1 Preparing the place of installation
Place of installation for stationary models
WARNING
Installation on foundations which are unsecured and cannot support the load
Personal injury and damage to property!
▷Make sure the foundation concrete is of sufficient strength (min. class 32.5 N to
EN 197-1 or equivalent).
▷Make sure the foundation has set firmly before placing the duckfoot bend on it.
▷Only place the duckfoot bend on horizontal and level surfaces.
▷Refer to the weights given in the data sheet/on the name plate.
Any resonances at the usual excitation frequencies (1 x and 2 x rotational frequency,
rotational noise) must be prevented both in the foundation and in the connected
piping, as such frequencies may cause extreme vibrations.
1. Check the structural requirements.
All structural work required must have been prepared in accordance with the
dimensions stated in the outline drawing/general arrangement drawing.
Place of installation for transportable models
WARNING
Placing the pump set on an unsecured and uneven mounting surface
Personal injury and damage to property!
▷Always place the pump set on a solid and level surface with the pump set in
vertical position and the motor on top.
▷Only place the pump set on a surface of sufficient load-carrying capacity.
▷Use appropriate means to secure the pump set against overturning or tipping
over.
▷Refer to the weights given in the data sheet/name plate.
Any resonances at the usual excitation frequencies (1 x and 2 x rotational frequency,
rotational noise) must be prevented both in the foundation and in the connected
piping, as such frequencies may cause extreme vibrations.
