Anschluss
Pumpe ist angekommen aber leider ohne flansch. Leider passt hier nicht wie beschrieben eine DN25 Flansch, da der Lochkreis Durchmesser 80mm ist.Woher bekomme ich einen passenden Flansch?

Attacco aria dimezzato e portata effetiva dimezzata!
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!
