SHR/250ST is equivalent to 12/10ST-AHR, a 10” discharge rubber lined slurry pump, which is widely used for corrosive slurry applications. SHR/250ST is horizontal centrifugal type heavy duty rubber lined slurry pump. Rubber Lined Slurry Pumps are used to handle tailings in various mining sectors. Plus, it can also be used to feed cyclones for sand washing plants, quarries, etc. SHR is high corrosion-resistant pump series for the hydraulic conveyance of liquids-solids of any type. It’s wet-end spare parts are made of natural rubber R55, a black soft natural rubber, which has superior erosion resistance to all other materials in fine particle slurry applications. The high erosion resistance of R55 is provided by the combination of its high resilience, high tensile strength and low Shore Hardness.
In fact, this model is a little special, because this pump is installed with metal impeller, although the inner liners are rubber. This way, the actual head of the pump will be higher than that of fully rubber lined.
Rubber Lined Slurry Pumps Applications:
Mine Dewatering; Sand Pumping; Manure Slurry; Oil Sands; Tailings and Aggregate; Coal Production etc.

How to Choose Slurry Pumps for Demanding Conditions? Six Application Cases Analyzed
From iron ore processing to thickener underflow, different slurry characteristics demand tailored pump designs. Key factors include material selection (high-chrome alloys, rubber liners, duplex stainless steel), structural design (double-casing, direct drive, large flow passages), and maintenance strategies. Choosing the right pump significantly reduces downtime and improves plant efficiency.
