Don slurry famfo, Wet Parts yana nufin sassan layi waɗanda ke hulɗa da kafofin watsa labarai na ruwa, yawanci sun haɗa da impeller, volute, farantin firam, daji makogwaro. A can sassa za su iya lalacewa cikin sauƙi ko gogewa yayin aiki kuma a sake su a kowane lokaci.
Yawancin lokaci famfo sassa da aka yi da baƙin ƙarfe, karfe, tagulla, tagulla, aluminum, filastik da dai sauransu Domin slurry farashinsa yawanci Ya sanya daga High Chrome gami, elastomer, polyurethane, yumbu da kuma wasu al'ada. Amma High chrome gami da elastomer yanzu sune babban kayan don famfunan slurry. A cikin 'yan shekarun nan wasu kamfanoni suna ƙoƙarin yin sassan jika ta yumbura kuma yawancin bayanai sun fito daga labs da masana'anta sun nuna cewa sassan yumbura na iya yin aiki na dogon lokaci fiye da high chrome alloy.
Domin chrome alloy abu, na kowa iri ne High Chrome Alloy (27% Cr), shi za a iya amfani da daga Ph 5 zuwa 12, da taurin iya zama zuwa HRC58, wanda yake shi ne mai matukar kyau zabi ga slurry iko da sufuri. Amma a wasu yanayi, Ph na iya ƙasa da 5, sannan mu gwada BDA49, zai iya ƙasa zuwa Ph4, galibi ana amfani da shi wajen sarrafa FGD.
Ana amfani da elastomer a cikin yanayi mai kyau da ƙananan Ph zuwa 2. Hakanan akwai rubbers da yawa don yanayi daban-daban, kamar R08, R26, R55, S02, da sauransu.
Kuma kwanan nan, Polyurethane ya zama sananne a wasu yanayi. Yana da kyau a lalata da yanayin lalacewa.
Menene ƙarin yumbu kayan don slurry famfo cikakke ne don maye gurbin elastomers da polyurethane a wani yanayi. Babban taurin da babban lalata suna sa shi ma yana iya maye gurbin injin ƙarfe a wasu yanayi.
Abubuwan da ke da mahimmanci don dakatar da yumbu slurry famfo don maye gurbin wasu su ne farashin da friability. Amma wasu kamfanoni sun warware waɗannan matsalolin, wato wasu kamfanoni sun yi nasara wajen kera fam ɗin yumbu slurry wanda zai iya tsayawa tasiri ta hanyar barbashi a cikin kafofin watsa labarai na ruwa kuma famfo ba shi da tsada sosai.
