These elements are plane-parallel to each other andare pressed together by the fixed cover and the loose cover.The fixed cover is connected to the traverse via connectingand tie bars. Together they form the press stand. The filterpackage is pressed together by a pressure unit which is in-corporated in the traverse and acts on the loose cover.Between the individual filter plates or chamber plates thereare filter cloths which have an outward sealing functionunder the pressure applied. The unfiltrate is conveyed into the chambers formed by the filter elements via a pump. Thefiltrate passes through the filter medium, leaves the filter viainternal or external outlet channels and is conveyed furtheraccording to its intended usage.Filtration produces a filter cake, which can be washed if required.In the membrane filter press every second plate is equippedwith an inflatable membrane. After the end of the filtrationprocess the membrane plates are pressurised with compres-sed air or water and forced against the cake. The cake is thusalso drained mechanically and the process accelerated.Benefits from the use of membrane plates:higher yield, virtually no lossesdrier filter cakefiltration cycle shortened by approx. 50 %MaterialsThe filter stand is made of nonrust stainless steel; paintedsteel is also available.The filter plates are of polypropylene although other materi-als are also possible as required. The filter cloths are generallyalso made of polypropylene.KFP 470 III with 30 chambersApplications and options for useFilter presses are used in all branches: foodstuffs and drinks,chemistry, pharmaceuticals or in the environmental sector.Filtration with filter aidsAs filter aids kieselguhr or perlite are generally added to facilitate filtration.PrecoatingBefore the start of actual filtration the filter cloth is coatedwith a layer of the filter aid. This prevents bleeding and pro-tects the filter cloth from blockage. We recommend theSTRASSBURGER dosing unit, e.g. DOS 500, for precoating and subsequent metered addition of the filter aid to ensureoptimum mixing and dosing of the necessary quantity of filter aids.Clean System type KFP-C-drip-freeA hermetically sealed filter can be achieved using filter platesequipped with an O-ring rim seal.The filter cloths have an all-round sealing bead and are attached within the plate.The patented sealing bead is designed so that no soiling canget behind the sealing bead.Filters remain clean and aseptic on the outside.Drainage of solid matter / Sludge drainageIn the case of products with a high solid matter content thisis retained in the chambers of the filter until a solid cake hasformed.Washing and drying of filter cakeSubstances to be recovered or removed can be washed outfrom the previously drained solid matter by adding certainsolvents. The plates and frames used for this purpose areequipped with special washing channels. The filter cake canbe additionally dehydrated using membrane plates followedby compressed air blown through the filter cake.Chamber plate Clean System and cloth with integrated rim seal(patented)Diagram showingoperationFiltering DischargeClosing pressureInletFiltrateOutletFilter cakeTypes KFP/MFP 470 KFP/MFP 630 KFP/MFP 800Plate size 470 x 470 mm 630 x 630 mm 800 x 800 mmCake thickness 30 mm 30 mm 30 mmType KFP/MFP Number of chambersNumber of platesFilter area m2Chamber volume lDimensions (MFP)LxWxH (approx. mm)Weightkg470 I 10 9 3,4 45 2000 x 890 x 1600 450470 II 20 19 6,8 90 2620 x 890 x 1600 353470 III 30 29 10,2 135 3240 x 890 x 1600 620470 IV 40 39 13,6 180 3860 x 890 x 1600 710630 I 10 9 5,9 80 2790 x 1060 x 1800 945630 II 20 19 11,8 160 3520 x 1060 x 1800 1150630 III 30 29 17,7 240 4240 x 1060 x 1800 1325630 IV 40 39 23,6 320 4990 x 1060 x 1800 1500630 V 50 49 29,5 400 5740 x 1060 x 1800 1675630 VI 60 59 35,4 480 6470 x 1060 x 1800 1850800 II 20 19 21,0 304 3055 x 1250 x 1900 2860800 III 30 29 31,5 456 3665 x 1250 x 1900 3095800 IV 40 39 42,0 608 4325 x 1250 x 1900 3525800 V 50 49 52,5 760 4985 x 1250 x 1900 3970800 VI 60 59 63,0 912 5645 x 1250 x 1900 4415800 VII 70 69 73,5 1064 6305 x 1250 x 1900 4850800 VIII 80 79 84,0 1216 6965 x 1250 x 1900 5305800 IX 90 89 95,5 1368 7505 x 1250 x 1900 5850800 X 100 99 105,0 1520 8015 x 1250 x 1900 6305Standardausstattung der Filter KFP und MFPWahlweise Ausstattung mit Membran- oder KammerplattenKomplett mit Schlauch- oder Kolbenpumpe zur BeschickungTrockenlaufschutz und elektrische SchaltautomatikDruckausgleichsbehälter und erforderliche ArmaturenManuelle oder elektrohydraulische AnpressungBei Membranplatten mit DruckluftanschlussKFP 470 painted steelwith overhang cloths forwaste waterStrassburger Filter GmbH + Co.
