3 Discharge nozzle
Design The pump set is designed with an axial fluid inlet and a radial outlet. The length of
the stage casing depends on the number of stages. The pump set is mounted on the
cover plate of a tank.
As an option the stage casing can be extended by one or more blind stages for
flexible immersion depths in the tank.
NOTE
Blind stages can cause a slight loss of pressure.
Function The fluid enters the pump via the suction nozzle and is accelerated outward in a
cylindrical flow by the rotating impellers. In the flow passage of the stage casing the
kinetic energy of the fluid is converted into pressure energy. The fluid is pumped to
the discharge nozzle, where it leaves the pump.
Sealing The pump is sealed by a standardised mechanical seal.
4.7 Scope of supply
Depending on the model, the following items are included in the scope of supply:
▪Pump
▪Electric motor
4.8 Dimensions and weights
For dimensions and weights refer to the general arrangement drawing/outline
drawing or data sheet of the pump set.

5.1 Safety regulations
DANGER
Installing electric equipment (motors) in potentially explosive atmospheres
Risk of explosion!
▷Comply with the applicable local explosion protection regulations.
▷Verify the test certificate of the motor.
▷Keep the test certificate close to the location of operation (e.g. in the foreman's
office).
5.2 Checks to be carried out prior to installation
Check the structural requirements.
The structural work required must have been prepared in accordance with the
dimensions stated in the outline drawing and/or general arrangement drawing.
5.3 Installing the pump set
The pump is designed for vertical installation in a tank.

üThe tank has been installed properly.
1. Place the gasket on the installation opening of the tank cover.
2. Position the pump set on the gasket.
3. Fasten the supporting flange of the pump set to the tank cover with four
hexagon head bolts.

5.4 Piping
5.4.1 Connecting the piping
DANGER
Impermissible loads acting on the pump nozzles
Danger to life from leakage of hot, toxic, corrosive or flammable fluids!
▷Do not use the pump as an anchorage point for the piping.
▷Anchor the pipes in close proximity to the pump and connect them properly
without transmitting any stresses or strains.
▷Take appropriate measures to compensate for thermal expansion of the piping.
CAUTION
Incorrect earthing during welding work at the piping
Destruction of rolling element bearings (pitting effect)!
▷Never earth the electric welding equipment on the pump or baseplate.
▷Prevent current flowing through the rolling element bearings.
NOTE
Installing check and shut-off elements in the system is recommended, depending on
the type of plant and pump. However, such elements must not obstruct proper
drainage or hinder disassembly of the pump.
üThe nominal diameters of the pipelines are equal to or greater than the nominal
diameters of the pump nozzles.
üTo prevent excessive pressure losses, adapters to larger diameters have a diffuser
angle of approx. 8°.
üThe pipeline is anchored in close proximity to the discharge flange and
connected without transmitting any stresses or strains. Its weight must not be
carried by the pump discharge flange.
1. Thoroughly clean, flush and blow through all vessels, pipelines and connections
(especially of new installations).
5.4.2 Permissible forces and moments at the pump nozzles
No piping-induced forces and moments (from warped pipelines or thermal
expansion, for example) must act on the pump.
5.5 Electrical connection
DANGER
Electrical connection work by unqualified personnel
Risk of fatal injury due to electric shock!
▷Always have the electrical connections installed by a trained and qualified
electrician.
▷Observe regulations IEC 60364 and, for explosion-proof models, EN60079.

WARNING
Incorrect connection to the mains
Damage to the power supply network, short circuit!
▷Observe the technical specifications of the local energy supply companies.
1. Check the available mains voltage against the data on the name plate.
2. Select an appropriate start-up method.
NOTE
Installing a motor protection device is recommended.
5.6 Checking the direction of rotation
WARNING
Hands inside the pump casing
Risk of injuries, damage to the pump!
▷Always disconnect the pump set from the power supply and secure it against
unintentional start-up before inserting your hands or other objects into the
pump.
WARNING
Reaching into the tank
Risk of personal injury!
▷When the cover plate is removed, never reach into the uncovered tank.
CAUTION
Drive and pump running in the wrong direction of rotation
Damage to the pump!
▷Refer to the arrow indicating the direction of rotation on the pump.
▷Check the direction of rotation. If required, check the electrical connection and
correct the direction of rotation.
The correct direction of rotation of motor and pump is clockwise (seen from the
motor end).
1. Start the pump set and stop it again immediately to determine the motor's
direction of rotation.
2. Check the direction of rotation.
The motor's direction of rotation must match the arrow indicating the direction
of rotation on the motor stool/bearing lantern.
3. If the motor runs in the wrong direction of rotation, check the electrical
connection of the motor and the control system, if applicable.
