Hydraulic Features
1/2 Wear ring:
double wear ring, pump fitted with casing wear ring andimpeller wear ring
3 Shaft:
– The shaft is made of stainless steel, adequately sized for the loads transmitted.
– The shaft is protected through the stuffing box with stainless steel or bronze sleeve.
– The sleeves are littled with O rings witth inside diameters to eliminate leakage between the shaft and the sleeve.
4/8 Casing:
– Double design valute: the radial thrust on the bearing is minimum and lower than the one with single valute design.
-High efficiency design
5 Soft packing
[ standard ] or mechanical ( on request )
6 Impeller:
– One piece casted impeller , with double suction.
– Due to the impeller double suction design there’s no axial thrust on the bearings
– Every impeller is balanced statically and dynamically
– Impeller keyed to the shaft and axially fixed by two half rings: due to this solution, maintenance and impeller dismantling are simpler than the one with threaded shaft sleeves.
7 Bearings
– Two heavy duty type bearings grease lubricated with grease flush through the bearing housing.
– The bearing bracket is carefully sealed off on both sides to prevent water or contaminants from seeping in.
– he bearing are protected from liquid entry by means of rubber seals
– Long life bearing designed for an average life of 100.000 hours, continuous running [MTBF].
