COMMON CONSTRUCTION FEATURES OF APP/ APO/ AEC-PML/ AEC-C PUMPS
A. VOLUTE CASING
Self venting casting prevents air lock with low radical force.
B. IMPELLER
Closed, Semi Open, Non clog, Vortex & Closed type staggered multi vane impellers to cover all application industry.
Back vane relives pressure on st. box & reduces leakages.
Balancing holes are provided to reduce axial trust.
C. RENEWABLE WEAR PLATE
Fitter with casing parallel to impeller profile to ensure the impeller clearance and to achieve the designed effiency of the pump. This also protects the liquid contact the wear plate seating area of the casting.
J. BEARING HOUSING
Sturdy bearing unit design. Non floating rotor both oil & grease can be used as lubricant. Since more pump models are coming under same bearing unit only few spares need to be kept for maintenance.
K. BEARINGS
Heavy duty angular contact ball bearings in drive end 2 nos. & 1 no. cylindrical roller/ deep groove ball bearing in the no drive end. Suitable for grease & oil lubrication.
Also available with extra heavy duty design for special applications 60 models in the type APP ensure the pump selection of any duty parameter within the operating range nearest to the best efficiency point.
