impeller vertical pumps 125 KKB 75-S

single-stage pumps with closed impeller, without lower slide bearing for pumping chemically aggressive liquids, pure and contaminated with solids less then 10 mm in size
hydraulic parts made of acid-resistant cast steel and steel
Q=60-270m³/h, H=10,8-47,9m, Tmax=373K

technical description
the pump body is provided with dual collecting coil; a strainer, mesh dia. 10 mm, is mounted at the pump inlet; the pump shaft is mounted in two ball bearings located in the bearing body above the plate;
the lack of lower slide bearing is a constructional advantage, since this bearing is subject to quick wear at the most, when pumping contaminated media
stuffing box packing - cord type
there is a possibility to feed water or air to the stuffing box hydraulic lock (hose inner diameter 8 mm);

on special order, L the pump submersion length may be increased by Ls (Ls max=800mm)
then, the minimum liquid level is 400 +Ls, when starting the pump
