Tobee® Warman SP SPR Vertical Slurry Pumps

Overview

Tobee TP/TPR vertical sump pump is designed for applications requiring greater reliability and durability than convention al vertical process pumps can offer. Fully elastomer lined or hard metal fitted. No submerged bearings or packing. high capacity double suction design. optional recessed impel ler and suction agitator available.

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 TPR 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 TP and from moulded elastomer for the TPR.

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 TP and TPR pumps. Strainers fit in column openings.

Lower Strainer - Bolted metal or polyurethane for TP; moulded snap-on elastomer for TPR.

Discharge Pipe - Metal for TP; elastomer covered for TPR. All wetted metal parts are completely rust protected.

Submerged Bearings - None

Agitation - An external agitator spray connection arrangement can be fit ted to the pump as an option. Alternati vely, a mechanical agitator is fitted to an extended shaft protruding from the impeller eye.

Materials - Pumps can be manufactured in abrasive an d corrosive resistant materials.

Applications

The rugged Tobee TP/TPR Heavy Duty Sump Pumps are avail able in a wide range of popular sizes to suit most pumping applications. Thousands of these pumps are pr oving their reliability and efficiency worldwide in: Minerals processing Coal preparation Chemical processing Effluent handling Sand and gravel

The Tobee TP/TPR design with either hard metal (TP) or elastomer covered (TPR)and almost every other tank, pit or hole-in-the ground slurry handling situation.

covered (TPR) components makes it ideal for: Abrasive and/or corrosive slurries Large particle siz es High density slurries Continuous or snore operation Heavy duties demanding cantilever shafts

Tobee TP/TPR Heavy Duty Sump 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 b e fitted to the bottom inlet to extend the depth of the pump by up to 2 metres. 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. To suit special requirements other Tobee pump wet ends can be fitted to the standard Tobee TP pump dry end.

Options - Metal or Rubber
