Description

Notation: EHM*3D E:Excellence H:High concentration M:Metal lined 3: Discharge size (inch) D: Frame type with maximum power The features are as followed: 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 *5 degrees by request and oriented to any eight positions to suit installations and applications. 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. Application: The type of EHM pumps are using for handing strong abrasive, high density slurries and low density, high head slurries in the metallurgical, mining, coal, power, building material and other industrial departments etc. For example: Coal washer processing, handling with the fine ore and tailings in metal mine, handing combined bottom and fly ash in a thermal power station.
