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].
