200SV-SP vertical spindle sump slurry pump is designed for applications requiring greater reliability and durability than conventional vertical process pumps can offer. Fully elastomer lined or hard metal fitted. No submerged bearings or packing. High capacity double suction design. Optional recessed impeller and suction agitator available. Mainly SP Metal Lined Vertical Sump Pump Parts: Impeller - Double suction impellers (top and bottom entry) induce low axial bearing loads and have heavy deep vanes for maximum wear resistance and for handling large solids. Wear resistant alloys, polyurethane and moulded elastomer impellers are interchangeable. The impeller is adjusted axially within the casting during assembly by external shims under the bearing housing feet. No further adjustment is necessary. 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. The assembly is grease lubricated and sealed by labyrinths; the upper is grease purged and the lower protected by a special flinger. The upper or drive end bearing is a parallel roller type whilst the lower bearing is a double taper roller with preset end float. This high performance bearing arrangement and robust shaft eliminates the need for a lower submerged bearing. Column Assembly - Completely fabricated from mild steel. G refers to submerged depth 1200mm; J refers to submerged depth 1500mm; L refers to submerged depth 1800mm; M refers to submerged depth 2000mm; Q refers to submerged depth 2400mm; Casing - Has a simple bolt-on attachment to the base of the column. It is manufactured from a wear resistant alloy for the SP and from moulded elastomer for the SPR. Upper Strainer - Snap in elastomer strainers fit in column openings to prevent overly large particles and unwanted refuse from entering casing of the pump. Lower Strainer - Bolt-on cast strainers on the metal pump and molded snap-on elastomer strainers on the rubber pumps protect the pump from oversize particles. Discharge Pipe - Metal for SP, elastomer covered for SPR. All wetted metal parts are completely rust protected. Fully Cantilevered - Eliminates submerged bearings, packing, lip seals, and mechanical seals that other vertical slurry pumps typically require. Agitation - An external agitator spray connection arrangement can be fitted to the pump as an option. Alternatively, a mechanical agitator is fitted to an extended shaft protruding from the impeller eye. Materials - Pumps can be manufactured in abrasive and corrosive resistant materials.
