Vertical Centrifugal Pump Corrosion - Resistant , Electric Slurry Pump No Submerged Bearing

SP/SPR 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 be 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.

Less wear, less corrosion

Wetted components are available in a wide range of alloys and elastomers. Weir Minerals selects the optimum combination of materials for maximum resistance to wear in virtually any industrial application, including those demanding both abrasion and corrosion resistance, and where larger particles or high density slurries are encountered. • Abrasion resistant Ultrachrome® A05 alloy.

• Abrasion/corrosion-resistant Ultrachrome® A49 alloy.

• Corrosion-resistant stainless steels.

• Natural and synthetic elastomers.

No submerged bearing failures The robust cantilever shaft avoids the need for lower submerged bearings which are often the source of premature bearing failure.

• Heavy duty roller bearings, above mounting plate.

• No submerged bearings.

• Labyrinth/flinger bearing protection.

• Rigid, large diameter shaft.

No shaft sealing problems

The vertical cantilever design requires no shaft seal. No priming required. The top and bottom inlet design is ideally suited for “snore” conditions. Less risk of blocking The screened inlets and large impeller passages reduce the risk of blockages. Zero ancillary water costs The vertical cantilever design with no gland or submerged bearings avoids the need for expensive gland or bearing flushing water.
