Assembling the suspension unit
Product description
The suspension units consist of a coupling base with a coupling flange, guide and mounting ele-
ments. The coupling base and the guide and mounting elements are assembled together to form
the suspension unit. The coupling flange mounted on the pump part enables the unit to be guided
precisely by the guide element onto the coupling base and therefore to be coupled to the pipe sys-
tem.
The connection between the coupling flange and the coupling base is performed automatically and
is established using the units own weight. The seal between the coupling flange and the coupling
base is made by the sealing ring in the coupling flange. This is pressed onto the coupling base dur-
ing operation and thereby seals the connection.
Gray cast iron and stainless steel are the materials used for the suspension unit. The gray cast iron
parts can also be additionally coated with special materials, for example, liquid ceramics, to protect
against abrasive and aggressive materials.
Rust-free steel pipes conforming to DIN2463 are used as guide elements. These are used a single or
double pipe guides. This does not affect installation.
The coupling bases differ in shape, size and design. Installation is the same for all coupling bases.
The individual parts are secured with the mounting sets supplied. These consist of anchor bolts for
the coupling base, machine bolts with hexagonal nuts for holders for pipe mountings and wood
screws with wall plugs and washers for holders for shaft mounting.
Please observe the relevant information sheets for installing the anchor
bolts. The specifications for the torque of each machine bolt can be
found in the tightening torque tables. These are both contained in the
appendix of this manual.
Proper use
Suspension units are used for submersed installation. This must be installed vertically in the operat-
ing area. The coupling flange acts as a guide between the machine and the coupling base. Suspen-
sion devices may not be inserted without guide elements.
This would result in the machine slipping from the coupling base and
could cause the machine to leak and cause its position to incline. It is
essential that guide elements are used.
Transport and storage
Before installing the suspension device, check it for damage or defects. Defective or damaged parts
may not be installed. Damaged coatings should be touched up before installation.
If the suspension device is to be stored, it must be washed and dried thoroughly. It should be stored
in a dry area which is not susceptible to frost.
Maintenance tasks
The components of the suspension unit should be regularly inspected for damage and looseness.
Damaged or defective parts should be replaced with original parts from the manufacturer immedi-
ately.
The suspension unit and the connected machine or system may only be
operated in perfect condition.
