Prezentare Pompa verticala in linie Grundfos TP 25-90/380V filet

Pompa in bavuri, intr-o treapta, cu cuplaj strans cu racorduri de aspirare si refulare de diametre identice. Pompele au un design \"top-pull-out\", adica capul de antrenare (motor, cap pompa si rotor) poate fi indepartat pentru intretinere sau service in timp ce carcasa pompei ramane pe conducta.
Pompa este echipata cu o etansare tip perna de cauciuc neechilibrata. Etansarea de arbore este conforma cu DIN EN 12756. Cuplajele conductelor sunt realizate prin cuplaje de imbinare PN 10 (ISO 228-1).
Pompa este echipata cu un motor asincron racit de un ventilator.
