What are the properties of the slurry pump

Slurry pump impeller maximum lift rubber lining is best not more than 63m, the maximum allowed by the line speed of not more than 30m/m; the bearing is generally used in rolling bearing, but also with oil or grease lubrication, and its working temperature should not exceed 75 ℃; and drive the pump can choose elastic coupling, the drive belt and hydraulic coupler so, where the couplings, V belt and belt wheel must have the safety protection cover; for the double shell pump rubber inner shell, the maximum size of solid particles in the slurry should be not more than 3mm, and for the double shell pump single pump and the metal inner shell shall not exceed the maximum size of the flow cross-sectional area size 80%; and slurry pump packing seal water pressure pump outlet pressure higher than 35kPa.
