Flowserve "MJ Slurry" pumps are single stage, vertical bottom suction centrifugal pumps specifically designed for handling abrasive slurries typical of mining and mineral process. A semi-concentric volute type casing is pedestal mounted with tangential discharge nozzle.
The closed impeller with rear pump-out vanes is capable of passing solids of various sizes. The rigid three point thrust bearing housing support permits precision bearing alignment. The casing is supported from the top plate by column pipe(s).
The pump has a water lubricated steady bearing located in a lower housing located above the impeller.Intermediate steady bearings will be supplied to maintain shaft critical speeds are above the operating speeds.
Pumps can be v-belt driven or direct driven by an electric motor. The bearing frame design varies according to the drive method.
All pumps are carefully inspected and prepared for shipment. All exterior machined surfaces are coated with a rust preventative compound and openings are provided with covers or plugs. The axial impeller running clearance is preset at the factory but should be checked prior to final alignment in case of tampering.Name Nomenclature
