Shijiazhuang Naipu Pump Co., Ltd.
250TV-TSP Vertical Slurry Pump is no submerged bearings or seals heavy duty cantilevered pumps, which ideal for a variety of submerged suction pumping applications. These pumps operate well in a variety of sump conditions, and can also be readily applied on floating dewatering or other floating pump platforms.
• Bearing Assembly - the bearing, shaft and housing ratio is very large to avoid problems with cantilever shaft operation in the first critical speed zone.
The components are lubricated with grease and sealed through a labyrinth; The top is cleaned with grease and the bottom is protected with a special lighter. The upper or driving end bearings are parallel roller type and the lower bearings are double tapered rollers with preset end floats. This high performance bearing configuration and rugged shaft does not require lower underwater bearings.
• Column Assembly – Completely fabricated from mild steel. The SPR model is elastomer covered.
• 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.
• Impellers - Double suction impellers (top and bottom inlets) generate lower axial bearing loads and have heavy duty deep blades for maximum wear resistance and handling of large solids. Wear resistant alloy, polyurethane and molded elastomer impeller are interchangeable. During assembly, the impeller is adjusted axially within the casting by means of an external gasket under the base of the bearing seat. No further adjustment is required.
• Upper Strainer – Drop-in metal mesh, snap-on elastomer or polyurethane for SP and SPR pumps. Strainers fit in column openings.
• Lower Strainer – Bolted metal or polyurethane for SP, moulded snap-on elastomer for SPR.
• Discharge Pipe – Metal for SP, elastomer covered for SPR. All wetted metal parts are completely rust protected.
• Submerged Bearings – None
• Agitator - Optional external agitator spray connection mounted on the pump. Alternatively, the mechanical stirrer is mounted on an extension shaft extending from the impeller hole.
• Materials – Pumps can be manufactured in abrasive and corrosive resistant materials.
