6/4D G Type River Dredging Sand Suction High Chrome Iron Cast Iron
Anti-Wear Sand Gravel Pump
Product Description
1. Gravel Sand pump (dredge pump) is designed as single casing
connected by means of clamp
bands and wide wet-passage.
2. The wearing parts are made of ultra chromium abrasion-resistance
alloys, long service life
and very low failure rate.
3.The pumps are designed for continuously transferring strong
corrosive big-solid -contained
slurry which the common slurry pump cannot transfer. They are
widely used in dredging,
sand excavation; mining, explosive-sludge in metal melting, etc..
4. G series gravel pump is often installed on cutter suction
dredger or barge.
5. Gravel pump outlet direction can be in any position of 360· This
type of pump possesses
the advantages of easy installation and operation, good performance
of NPSH and abrasion resistance.
6. The discharge direction of pump can be oriented in any direction
of 360°
Construction of Gravel Pump:
Construction of Gravel Pump is of single casing connected by means
of clamp bands and wide wet passage. The wet parts are made of Ni
hard and high chromium abrasion-resistance alloys. The discharge
direction of punp can be oriented in any direction of 360 degree.
This type of pump possesses the advantages of easy installation and
operation, good performance of NPSH and abrasion resistance.
Material
The material for standard G 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.
