Products Details

Type VSD pumps are vertical, centrifugal slurry pumps submerged in sump to work. They are designed for delivering abrasive, large particle and high density slurries. These pumps have no need of any shaft seal and sealing water. They can also be operated normally for insufficient suction duties.VSD here means Vertical Sump Duty Slurry Pump. which is suited for the working condition of deeper level. The guide bearing construction is added to the pump on the basis of the standard pump, so the pump is with both more steady operation and wider application range, but flushing water should be attached to the guide bearing. Wet parts of type VSD pump are made of abrasion-resistant metal All parts of type VSD pump immersed in liquid are lined with rubber outer liner. They are suited to transport no-edge angle abrasive slurryMetallurgical, Mining ,Coal ,PowerBearing Assembly一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一Completely fabricated from mild steel. The VSDR model is elastomer covered Casing一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 VSDR. Impeller一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 adusted axially within the casting during assembly by external shims under the bearing housing feet. No further adjustment is necessary. Upper Strainer一Drop-in metal mesh; snap-on elastomer or polyurethane for VSD and VSDR pumps. Strainers fit in column openings. Lower Strainer一Bolted metal or polyurethane for SP; moulded snap-on elastomer for VSDR. Discharge Pipe一Metal for VSD; elastomer covered for VSDR. All wetted metal parts are completely rust protected. Submerged Bearings一None Agitation一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一Pumps can be manufactured in abrasive and corrosive resistant materials
