1. ERIKS operating companies
ECON bucket filters are being delivered by several ERIKS operating companies on a worldwide
basis. In this manual these will be referred to as ‘ERIKS’, the individual terms of delivery of the
ERIKS operating company having executed the order are applicable.
2. Product description
The ECON bucket filters are designed according the information in our latest catalogue or see our
website www.eriks.com and should be used in accordance with the applicable pressuretemperature rating as stated on this website. ECON strainers are provided with casted markings
according to EN 19. The marking makes the identification of the strainers easier and contains:
- size (DN)
- nominal pressure
- body material marking
- heat numbers (when required)
- arrow, indicating the medium flow direction
- ECON logo
3. Requirements for maintenance staff
The staff assigned to assembly, operating and maintenance tasks should be qualified to carry out
such jobs and in any circumstance, ensure personal safety
4. Transport and storage
During transport and storage the filters should always be protected against external forces,
influence and destruction of the painting layer as well. The purpose of the painting layer is to
protect the filter against rust, during transport and storage. The strainers should be stored in an
unpolluted space and should also be protected against all atmospheric circumstances. There
should be taken care of the temperature and humidity in the room, in order to prevent condensate
formation.
5. Function
ECON bucket filters are used to protect other pipeline components downstream from damage due
to debris and dirt in the system. The medium to be filtered flows through the filter insert from the
inside to the outside. The flow direction is marked on the body of the filter. The particles remain in
the filter and can be removed with the filter insert. The filter is only suitable for use in a horizontal
pipeline.
6. Application
ECON bucket filters are designed for standard operating conditions. The standard allowable
differential pressure/clogging rate for the insert is 1,5 bar and shall not be exceeded, this can lead
to equipment damage. For the use of extreme conditions e.g. aggressive or abrasive media, it is
recommended to mention this at the ordering stage, to verify whether the filter is suitable. The
installation designer is responsible for the filter selection, suitable for the working conditions. The

filters are unsuitable, without written permission of an ERIKS company, to apply for hazardous
media as referred into Regulation (EC) No 1272/2008.
7. Installation
During the assembly of the ECON bucket filters, the following rules should be observed:
- the filters should be checked before installation if they have not any defects caused by
transport and/or storage.
- make sure that the applied filters are suitable for the working conditions, medium used in
the plant and the right system connections, according to pressure and temperature limits
and that the insert is installed with the correct perforation/mesh.
- protective flange hole plugs must be removed
- bucket filters can only be used in liquid systems as MDO, oil, water and seawater and in a
horizontal pipeline, with enough clear necessary space above the filter for removing the
insert out of the filter.
- during fitting, the proper flow direction has to be considered.
- the filters must be stress free mounted between the flanges, supports must be arranged to
prevent any additional stress, caused by the weight of the filter or the pipeline.
- bolted joints on the pipeline must not cause additional stress resulted from excessive
tightening, user shall select proper bolts and gaskets according the working temperature,
working pressure and medium.
- the standard allowable differential pressure/clogging rate for the insert is 1,5 bar and shall
not be exceeded and can lead to equipment damage.
Operating instructions for startup.
- open the venting device on top of the filter until liquid escapes
- close venting device
- filter is ready for operation
