Mining Slurry Pump (EHM-12ST SLURRY PUMP)
1. EHM Slurry Pump Introduction:
The Frame Plates For Type EHM Pumps Have Replaceable Wear-Resistant Metal Liners. The Impellers Are Made Of Wear-Resistant Metal. The Frame Plate Liner And Impeller For EHM Pump Are Adoptable Of Hard Metal Only.
Bearing Assembly Use Cylindrical Structure, Adjusting The Space Between Impeller And Front Liner Easily, Being Removed Completely When Being Repaired. Bearing Assembly Use Grease Lubrication.
The Shaft Seal Could Use The Packing Seal, Expeller Seal And Mechanical Seal. The Discharge Branch Can Be Positioned At Intervals Of 45 Degrees By Request And Oriented To Any Eight Positions To Suit Installations And Applications.
Here Are The Drive Types, Such As V Belt Drive, Gear Reducer Drive, Fluid Coupling Drive, And Frequency Conversion Drive Devices.
Wide Performance, Good NPSH And High Efficiency. The Pump Of This Type May Be Installed In Multistage Series To Meet The Delivery For Long Distance.
2. Application:
Series EHM slurry pumps are widely used in the mining, coal washery, power plant, metallurgy, petrochemical, building material, dredging and other industrial departments, etc. It is used in the various working sites including hydrocyclone feeding pump, magnetic separator feeding pump, underflow slurry pump (thickener underflow pump, filter separator underflow pump), flotation feeding pump, vibrating sieve feeding pump, shaking grading pressure pump, concentrate pump, and tailing pump.
