Type G(orGH) gravel pumps are designed for continuously handling the most difficult high abrasive slurries which contain too big solids to be pumped by a common pump. They are suitable for delivering slurries in Mining, Explosive sludge in metal melting, Dredging in dredger and river course, and other fields. Type GH are high head pumps.
Features
-High head & High pressure & High Efficiency
- Anti-corrosive and wear resistant wet end parts
-Long working life
-Easy to maintain
-Exchanged with other pumps

Shaft sealing for a slurry pump :
The packing seal is the most commonly used seal type of slurry pumps, it is composed by packing ring, packing sleeve, packing, packing gland, stud bolts and nuts.
Through the packing and shaft surface contact pressure, it prevents the medium leakage to achieve the purpose of sealing. The existence of many of the small gap and the groove, making it possible to achieve necessary sealing pressure by sufficient pressing forcing the packing material into elastoplastic deformation to reduce the gap between the contact seal surface.
When the infiltration of the media or the media is gas, the penetration leakage through the packing is almost inevitable, but the specific mechanism of this kind leakage will be explored further. For the vast majority of the liquid medium, the leakage mainly through the interface between the packing and the moving parts. For slurry pumps, the large size particles make it difficult to close the small gaps in shaft seal, so,when pumping the corrosive liquids or the liquids contains corrosive slurry, it will penetrate into the packing seal, these will cause wear and corrosion of the shaft.
Especially when two kinds of materials are constituting the friction pairs in the electrolyte solution, there may occur the galvanic corrosion that is much more accelerated corrosion damage to the shaft. So, when transporting toxic, corrosive and poisonous liquid, due to the small amount of leakage, and even allowed no leakage, it can not use packing seal.
