U slučaju abrazivnog i korozivnog korišćenja, u nekim komponentama može doći do prirodnog habanja. U pogledu gornje primene do habanja može doći pre svega kod rotora, agitatora, usisne ploče, rukavca vratila, uljanog prstena, mehaničke zaptivke, kućišta pumpe, sita, kućišta motora i ispusne spojnice. Radni vek ovih delova može znatno da varira zavisno od radnih uslova i može biti kraći od garantnog perioda.
U tom smislu obratite pažnju na naše opšte uslove korišćenja koje vam takođe na zahtev šaljemo poštom.
