2Páginas

Filtration of all liquids. For installationinto suction or pressure pipework to protect plant components (valves, pumps, pressure gauges, nozzles etc.) preventing accumulation of dirt and sludge. > The Duplex Filter 2.04.5 allows chan- ge-over during operation without pressure-loss. The filter is compact and easy to maintain, requiring only manual cleaning when maximum al- lowable pressure drop is reached. When maximum pressure drop is rea- ched the standby filter chamber is brought on line simultaneously as the dirty one is isolated by means of the change-over valve. After venting, thedirty element can be removed, clean-ed and refilled to be the standby filterchamber. > Q [m 3 /h] 100 0,10,20,30,50,7 908070605040 170.500 V = 1 m/sV = 2 m/sV = 3 m/sV = 4m/s 110.390 30201510987654321 110.260 110.210 90.14590.095 ֕Switch change-over valve to cleanfilter chamberRelease pressure in the contamina-ted filter chamber by means of ven-ting screwՕLift the cover of the contaminated fil-ter chamberRemove filter element ՕSoak filter element in cleaning fluid,e.g. BOLL-CLEAN 2000, and cleanwith compressed airFor details see operating instructions manual filter element cleaningԔ Filter housing of cast iron or ductileiron; internally nickel lined for waterapplication ՕChange-over valve of cast iron; wa-ter filters rubber-linedOptionally > p [bar] Differential-pressure p as function of flow Q with oil of viscosity 50 cst and filtration degree 40 star-pleated or basket > յ microns. filter element , star-pleated ele-ment also available as disposable fil-ter elementFilter fineness: 10 microns to 5 mmՕOperating pressurecast iron up to 16 bars ductile iron up to 25 bars > Differential pressure indicator type4.36 can be supplied fitted at factory.The filter elements can be fitted with magnetic bars . >
