Leider passt hier nicht wie beschrieben eine DN25 Flansch, da der Lochkreis Durchmesser 80mm ist. Woher bekomme ich einen passenden Flansch? Review: Arrivata e funzionante. Tuttavia l'attacco dell'alimentazione aria non é da 1/2" NPT bensì da 1/4 metrico! Questo ne riduce notevolmente la portata, ossia a tutti gli effetti porta la metà di quanto potrebbe e soprratutto non è sostituibile salvo rifare il foro e la filettatura, insomma impossibile! ## Features - Premium Double PTFE Diaphragms: Our air-operated double diaphragm pump adopts PTFE diaphragms, durable, corrosion-proof, and long-lasting.
