The China SP/SPR  is a vertical, centrifugal slurry pump. It is suitable for delivering abrasive or corrosive slurry and the pump is always immersed in the sump or pit to operate. The sump pump is divided into type SPand SPR, but they have the same construction. The wet-parts and shaft for type SP is made of metal material for delivering abrasive slurry and for type SPR are lined with corrosive-resistant rubber for delivering corrosive slurry. The SP(R) sump pump is widely used for mining, chemical industry and each factory and mine enterprise.

The China SP/SPR heavy duty cantilever sump pump is designed for applications requiring greater reliability and durability than conventional vertical process pumps can offer. The heavy duty cantilever design makes the China SP/SPR sump pump ideally suited for heavy continuous handling of abrasive and corrosive liquids and slurries whilst submerged in sumps or pits. China  SP/SPR sump pumps offer you:

• Reliability - by design.

• Low spares costs - from long wear life.

• Low energy costs - from maintained efficiency.

Design Features:

Less wear, less corrosion

Wetted components are available in a wide range of alloys and elastomers, from which 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 A05.

• Abrasion/corrosion-resistant A49 .

• 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 mountingplate.

• 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.
