BOLLFILTER Simplex TYPE 1.12.2 Application Filtration of all liquids. For installation with flanged connections DN 25 – DN 80 optionally with integrated steam heating into suction or pressure pipework to protect downstream equipment (pum­ s, bearings, heat exchangers, p valves, pipework etc.) against contamination or accumulation of mud. Operation The filter is completely maintenancefree except for checking of the seals and cleaning of filter elements. The pressure drop indicates the contamination degree of the filter. To clean the filter element, the installation must be shut-down or the filter isolated. Cleaning Depressurize the filter chamber by means of the venting screw. Lift the housing cover, remove the filter element, rinse it with the cleaning fluid, e.g. BOLL-CLEAN 2000, and clean it by compressed air. (See operating instructions ‘filter element cleaning‘). Technical Characteristics • Filter housing made of cast ductile iron (DN 25 to DN 80) or cast stainless steel (DN 25 and DN 50) • Cover safety device • Magnetic bar inside the filter element • Minimal pressure losses • Steam heating • Most compact construction • Bottom fastening for filter size • Minimal number of components • Easy cover fastening with only two • Flanged connections according to DIN, ANSI, JIS • Filter elements: star-pleated 1 ele­ ment or basket 2 element, option• Grade of filtration: 10 micron to 5 mm • Operating temperature: -10°C to 160°C ACCESSORiES • Differential pressure indicator optical / optoelectrical Pressure stages / Dimensioning Cast ductile iron Cast stainless steel ally as disposable element
