Materials Abstract

Housing and Cover St 35.8/P265 GH, 1.4541 1.4571 The double filter consists of two individual filters which can be operated alternatively or in parallel via 3-way ball cock fittings. The sin-gle filters of the standard design consist of welded steel housings provided with covers which are fixed by means of bolts and nuts. The scope of delivery will comprehend the venting device within the cover and the draining device within the housing. The filter can be equipped with basket or ring strainer inserts. The filter inserts consist of a perforated plate optionally covered with cloths having different mesh widths. The medium to be filtered will flow through the strainer from the inside to the outside.

Installation

Switch-over device 1.0619/1.4408/TFM-25% Glas/FPM 1.4571/1.4408/TFM-25% glas/FPM The installation into pipings will be effected by means of flanges. Please ensure that the filter of the standard design is vertically in-stalled - with the cover located at the top without any additional loads - and mechanically stress free. The medium to be filtered should enter the filter via the upper connecting elbow. A wrong installation may lead to functional disturbances of the filter. The (flange position - type I or type II (see Fig. No. 3) - should be indicated in your order but, if required, it can be modified by reposition-ing the elbow. Vent valve - - Air relief cock - Nickeled steel, St, A4 Vent screw A4 - Drain plug A4 -

Commissioning

1. shift the switch-over lever into the operating position. 2. open the venting device until the liquid emerges. 3. close the venting device. The filtering jug is ready to be used Drain cock - Nickeled steel, St, A4

Additional filter

Cleaning

1. Depressurize the filtering jug shut down using the venting or draining devices. 2. Loosen the filter lock and lift off the cover. 3. Using the draining device, empty the filter at least down to the level of the strainer support. 4. Pull the strainer insert out of the filter housing. Now the strainer can be cleaned by blowing out or blasting using compressed air, steam or water. If necessary the strainer should be soaked and cleaned using a suitable agent.. Possibly an optimal cleaning will be obtained using ultrasonics. In case of all these modes of cleaning, you should always take care not to damage the filter cloth. 5. During the reassembly following the disassembly procedure in the reverse, the sealing elements should be checked if they are intact. If necessary they should be replaced.

Heating system

(Suffix of the type designation code: ......................H) As a starting aid and in order to achieve a permanent decrease of the viscosity of the medium to be filtered, the filter can additionally be equipped with a heating system. The heating system will be designed as steam or hot water dome heating system or as an electric heating system respectively which can be supplied in steel or A 2 and which will have a flange connection DN 15 or an Ermeto coupling respectively. Further-more, we would like to offer you a steam heating as a On customer`s request further design and material variants will be manufactured and supplied. Please let us have your relevant inquiry. heating system within the outer mantle . Upon request we shall let you have the data of this particular design. 11.2003 © by Georg Schünemann GmbH, Bremen, Subject to modifications 11.2003 © by Georg Schünemann GmbH, Bremen, Subject to modifications
