Description
The features of HDA and HDR slurry pump
1.The frame plates of HDA slurry pump have replaceable wear-resistant metal liners. The impellers are made of wear-resistant metal. The frame plate liner and impeller for HDA pump are adoptable of hard metal only. While HDR slurry pump wet parts are made from rubber, they are interchangeable with metal spare parts.
2.Bearing assembly of this kind of slurry pump use cylindrical structure, adjusting the space between impeller and front liner easily, being removed completely when being repaired. Bearing assembly use grease lubrication.
3.The shaft seal of this kind of slurry pump could use the packing seal, expeller seal and mechanical seal. 4.The discharge branch can be positioned at intervals of 45 degrees by request and oriented to any eight positions to suit installations and applications.
5.Here are the drive types, such as V belt drive, gear reducer drive, fluid coupling drive, and frequency conversion drive devices.
6.Wide performance, good NPSH and high efficiency are main character of these kinds of slurry pump. The pump of this type may be installed in multistage series to meet the delivery for long distance.
