Tobee® SPR Rubber Lined Vertical Slurry Pump

Tobee^® SPR Rubber Lined Vertical Slurry Pumps are available in various standard lengths to suit common sump depths, for very deep sumps or where high shaft speeds limit the length of the pump, a suction extension pipe can be fitted to the bottom inlet to extend the depth of the pump by up to 2 meters. Pumping is maintained even when the top inlet is not submerged, thus enabling the level of liquid to be lowered right down to the bottom inlet or the bottom of any suction extension pipe. The wet parts of SPR vertical sump pump is interchangeable with the SP series hard metal lined heavy duty sump pumps.

Design Features:

√ 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. 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.

√ 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.

√ 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

√ 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.
