As a single-stage-single -suction horizontal cantilever-type centrifugal one, the model ZM (slag) slurry pump is designed to absorb the advantages of similar products from home and aboard. It is convenient to install and easy to disassemble and repair.
The pump head part: model ZM (slag) slurry pump has double pump casings in the structure. That is to say, it is made up of the front pump casing, back pump casing, front guar plate, back guard plate, sheathing, and shaft casing. The flow contact parts are made of Cr26、Cr30 materials, while the front and
back pump casings are made of gray cast iron or nodular cast iron. The pump outlets can be installed at intervals of 450， at eight angles, according to the user's requirements. At the front and back cover plates, there are back blades to lower leakage, so as to extend the life and increase the efficiency of the pump.
The shaft seal part: The shaft seal has two forms: the shaft seal of the auxiliary blade wheel and the filling seal. The shaft seal of the auxiliary blade wheel is featured with no thinning or slurry, long life of the seal, a good seal effect, etc. The filling seal has a simple structure and is convenient to repair.
Drive part: Model ZM (slag) slurry pump can be directly driven. The bearing support, in combined with the bearing body, has high strength in structure, the big diameter of the pump shaft, good flexibility, and a short cantilever. Even if in bad working conditions, no bending and vibration can arise. Because of using heavy single-line cone roller bearing, it can stand the axial and radial loads of the pump. The shaft is lubricated with oil. At both ends of the bearing body, there are bearing covers, inside of which there is a seal ring. The ring can effectively protect ore slurry from penetration and the lubricating oil from leaking. This can make sure that the bearing can run safely. In accordance with users' requirements, the drive part of the bearing can be in double-open type and lubricated with thin oil. This can lower the temperature of the shaft.
