Tobee 250TV-SP Vertical Slurry Pump is a heavy duty cantilevered pump with no submerged bearings or seals, which is 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.
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.
