| The frame plate liners for EHM series pumps  The frame plate liners for EHM series 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, which helps adjust the space between impeller and cover plate liner easily, and being removed completely when being repaired. Bearings use grease lubrication. The shaft seal could use the packing seal, centrifugal seal and mechanical seal. The discharge side 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, 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. 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. write your comments about the article :: © 2008 Construction News :: home page |
