DN Gravel Pumps are horizontal single-casting slurry pumps with wide passage to transfer gravel sand or slurry with big particle size. The wet parts are made of Ni-hard and high-Chrome alloys to ensure longer service life.
DN Gravel Pump has far better performance than common pumps in dredging, sand mining, barge loading and mineral processing, etc. Featured with all the advantages of MPG, MPGH series gravel pumps achieved extra high head for special working conditions.
The material for standard GN series gravel pump is high-chrome alloy. This kind of material is very wear resistant and has excellent performance under erosive conditions.
KmTBCr27: hard carbides within its microstructure provides higher abrasion resistance.
There are 3 standard shaft seal methods:
Packing seal: it is the lowest in cost.
Expeller seal: it is the most commonly used.
Mechanical seal: it has the best seal effect, but high in cost. also has strict requirement of flush water.
