Tobee 4x3C-AH Slurry Pump with ceramic shaft sleeve C075J04 that widely used as ash handling pump in as handling system in power plant. Slurry Pump Ceramic Shaft Sleeve, which has undergone destructive field tests for over 18 months, has proved to extend part life several times that of steel shaft sleeves on the same pump, same service. Total maintenance costs and down-time were reduced accordingly. Tobee's slurry pump ceramic shaft sleeves are precision formed of high density alumina, fired, and ground to size. The hardness of ceramics (9.0 to 9.5 MOH Scale) resists this destructive action, In addition, the ceramic coated sleeve surface is highly polished which, together with its lower co-efficient of friction, results in extended sleeve life and long service from the packing. One of the problems of concern to operators of centrifugal slurry pumps is the wear of shaft sleeves and the deterioration of packing material in the gland. This matter has also been under study by the Materials Research and Development Department of TOBEE PUMP for some time. The result is the development of a shaft sleeve of much superior wearing qualities. Tobee Slurry Pump Ceramic Shaft Sleeve, which has undergone destructive field tests for over 18 months, has proved to extend part life several times that of steel shaft sleeves on the same pump, same service. Total maintenance costs and down-time were reduced accordingly. Slurry Pump Steel Shaft Sleeve has always been the here-to-fore accepted material for shaft sleeves for most centrifugal slurry pumps. However, steel in shaft sleeves is subject to pitting, fritting and wear that often results in short part life. So Tobee Pump developments of a ceramic coating shaft sleeve of much superior wearing qualities.
