Suction head/suction lift line
WARNING
Foreign objects in the intake/suction line
Personal injury and damage to property!
▷Make sure that the intake area (e.g.: intake chamber/intake channel) is clean
and free from foreign objects.
▷Make sure that the suction line is clean and free from foreign objects.
▷Protect intake area leading into any existing suction line against ingress of
foreign matter.
▷Any existing suction-side flow distribution equipment must be installed firmly
and securely.
1. Check suction-side conditions. No foreign objects must enter the pump.
2. Clean the intake or suction line as necessary.
3. Install suction strainer if required.
5.3 Installing the pump set
NOTE
See other applicable documents for the type of installation of the delivered design.
NOTE
See other applicable documents for other types of installation than those
documented here.
NOTE
Mechanical seals are shipped separately. They are not installed in the pump
(Installation guidelines see (ðSection9,Page54)
Depending on the type of installation, relevant instructions need to be carried out as
applicable:
▪Prepare and install the base frame/supporting frame/foundation blocks/
foundation rails/foundation ring.
▪Install the pump and motor on the prepared base frame/supporting frame/
foundation blocks/foundation rails/foundation ring.
▪Check the alignment of pump and motor.
▪Align the pump with the piping.
▪Install and align the coupling.
▪Connect the piping.
▪Perform precision alignment of pump and motor, if possible with larger motors.
▪Remove any transport locks.

Installation on existing elements
DANGER
The pump or individual components could slip out of the suspension arrangement
Danger to life from falling parts!
▷Always transport the pump or components in the specified position.
▷Never attach the suspension arrangement to free shaft areas on the pump.
▷Refer to the weights and centre of gravity indicated for the individual
components.
▷Observe the applicable local health and safety regulations.
▷Use suitable, permitted lifting accessories.
DANGER
Incorrect assembly
Risk of injury from lifting heavy components and placing them upright
▷Only transport and place the pump and individual components upright in the
specified position.
▷Select a suitable lifting accessory according to the weight of the component
and the installation requirements.
▷Always use the attachment points provided for the lifting accessories.
üThe relevant general arrangement drawing is available.
üThe foundation has the required strength and characteristics for the loads
indicated in the general arrangement drawing.
üThe foundation complies with the dimensions given in the general arrangement
drawing.
1. Transport and place the pump (set) upright in accordance with the other
applicable documents.
2. Lower the pump onto the foundation elements provided.
3. Align the pump with the piping and connect it to the foundation.
4. Mount the motor and motor stool as described in the motor manufacturer's
operating instructions.
5. Align the coupling as described in the coupling manufacturer's operating
manual.
5.3.1 Checking and adjusting the pump rotor clearance
CAUTION
Incorrect setting of pump rotor
Damage to the pump/pump set components
▷Establish the permissible clearance by raising the pump rotor in axial direction.
The rotor must always be checked and re-adjusted after the first installation or
following complete dismantling. It must always be checked and re-adjusted before
the motor and the coupling plate are fitted.

üSuitably dimensioned lifting equipment and lifting accessories are available.
üThe pump has been completely assembled.
üThe drive has not been mounted.
üThe hexagon nuts for re-adjusting the gland follower have been loosened.
üThe pump rotor rests with the blades inside the wear ring.
üThe pump has been correctly aligned.
1. Measure the distance from the contact face of the drive lantern to the end of
the top shaft. Record the measured value.
2. Raise the pump rotor by turning the adjusting nut clockwise until the pump
rotor has reached the value specified for the axial clearance in the Axial
clearance table.
