Gravel Ocean Sea Sand Transfer Pump Introduction
Gravel sand pumps are designed for continuously handling the most difficult higher abrasive slurries which contain too big solids to be pumps by a common slurry pump. The pump body(casing & impeller) are made of 27% high chrome alloy, the extra thick pump case let the pump anti-wear and need lowest maintenance cost.

Gravel Ocean Sea Sand Transfer Pump Structure
impeller:The impeller, either elastomer or high-chrome material, is the main rotating component which normally has vanes to impart the centrifugal force to the liquid.
Casing:Split outer casing halves of cast contain the wear liners and provide high operation pressure capabilities. The casing shape is generally of semi-volute or concentric, efficiency of which are less than that of the volute type.
Shaft and Bearing Assembly:A large diameter shaft with a short overhang minimizes deflection and vibration. Heavy-duty roller bearings are housed in a removable bearing cartridge.
Shaft sleeve:A hardened, heavy-duty corrosion-resistant sleeve with O-ring seals at both ends protects the shaft. A split fit allows the sleeve removed or installed quickly.
Shaft Seal:Expeller seal, Packing seal, Mechanical seal.
