Tobee® Slurry Pump Impeller FAM10147R55 is interchangeable with AH/HH/L/M slurry pump impellers, the Impeller is one of the most important parts for slurry pump.
Materials technology - R55
To further assist one aspect of pump’s wear performance, the R 55 material has been introduced. R55 is a premium grade material for use in a high wear application. It is a black natural rubber, of low hardness and is used for pump liners and impellers, as well as cyclones. Superior physical properties give increased cut resistance to hard, sharp particle slurries, resulting in improved wear characteristics. It is particularly suitable for large particle erosive slurry applications such as mill discharge applications. Tests have consistently shown that wear life with R55 can be increased by as much as 50% over previous materials.
The R55 material has replaced our previous natural rubber grades such as R08A, R24, R26A, W411 and W413, brought about by progressive improvements in materials technology.
Tobee® offer rubber materials in: Natural rubber R55, R08, R26, R33, S01(EPDM), S10(NBR), S21(Bromobutyl), S31(Hypalon), S42(Neoprene) etc as well as polyurethane.

RU08 |
Standard Impeller Rubber |
Natural Rubber |
RU08 is a black natural rubber, of low to medium hardness. R08 is used for impellers where superior erosive resistance is required in fine particle slurries. The hardness of RU08 makes it more resistant to both chunking wear and dilation (i.e.: expansion caused by centrifugal forces) as compared to RU26. RU08 is generally only used for impellers. |
|
RU26 |
Anti Thermal Breakdown Rubber |
Natural Rubber |
RU26 is a black, soft natural rubber. It has superior erosion resistance to all other materials in fine particle slurry applications. The antioxidants and antidegradents used in RU26 have been optimized to improve storage life and reduce degradation during use. The high erosion resistance of RU26 is provided by the combination of its high resilience, high tensile strength and low Shore hardness. |
|
RU33 |
Natural Rubber (Soft) |
Natural Rubber |
RU33 is a premium grade black natural rubber of low hardness and is used for cyclone and pump liners and impellers where its superior physical properties give increased cut resistance to hard, sharp slurries. |
|
RU55 |
Anti Thermal Natural Rubber |
Natural Rubber |
RU55 is a black, Anti-corrosive natural rubber. It has superior erosion resistance to all other materials in fine particle slurry applications. |
|
SY01 |
EPDM Rubber |
Synthetic Elastomer |
|
|
SY12 |
Nitrile Rubber |
Synthetic Elastomer |
Elastomer SY12 is a synthetic rubber which is generally used in applications involving fats, oils and waxes. S12 has moderate erosion resistance. |
|
SY31 |
Chlorosulfonated Polyethylene (Hypalon) |
Synthetic Elastomer |
SY31 is an oxidation and heat resistant elastomer. It has a good balance of chemical resistance to both acids and hydrocarbons. |
|
SY42 |
Polychloroprene (Neoprene) |
Synthetic Elastomer |
Polychloroprene (Neoprene) is a high strength synthetic elastomer with dynamic properties only slightly inferior to natural rubber. It is less effected by temperature than natural rubber, and has excellent weathering and ozone resistance. It also exhibits excellent oil resistance. |
|
SY45 |
High Temperature Hydrocarbon Resistant Rubber |
Synthetic Elastomer |
SY45 is an erosion resistant synthetic rubber with excellent chemical resistance to hydrocarbons at elevated temperatures. |
|
SY51 |
Fluoroelastomer (Viton) |
Synthetic Elastomer |
SN51 has exceptional resistance to oils and chemicals at elevated temperatures. Limited erosion resistance |
