Design features:
1.Vertical,Submerged,Cantilevered shaft sump slurry pump.
2.Bearing Assembly – The bearings, shaft and housing are generously proportioned to avoid problems associated with the operation of cantilevered shafts in the first critical speed zones.
3.Column Assembly – Completely fabricated from antiwear carbon steel. The LYJ(R) model is rubber covered.
4.Shaft – Different length of the pump drive shaft or suction extension pipe could be selected
5.Casing – LYJ(R) has a simple bolt-on attachment to the base of the column.
6.Impeller – Double suction semi-open impeller design, Wear resistant alloys, polyurethane and moulded elastomer impellers are interchangeable.
7.Upper Strainer – Drop-in metal mesh; snap-on elastomer or polyurethane for LYJ and LYJ(R) pumps. Strainers fit in column openings.
8.Lower Strainer – Bolted metal or polyurethane for LYJ pumps; moulded snap-on elastomer for LYJ(R) pumps.
9.Discharge Pipe – Metal for LYJ pumps; Rubber covered for LYJ(R) pumps. All wetted metal parts are completely rust protected
10..Agitator option keeps solids in suspension,Alternatively, a mechanical agitator is fitted to an extended shaft protruding from the impeller eye.
11.Don’t need any seal and seal water.
