High Chrome Cast Iron OEM Dredging Large Capacity Centrifugal Anti-Abrasive Long Life Sand Gravel Pump
Sand Gravel Pump Introduction:
1. 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 sand 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 pump have non-clogging wide flow channel and thick volute and high efficiency closed impeller.
The advantage of G sand /gravel pumps
| 1 | Large drdging depth, high density of dredging mud, good NPSH and stronger suction lift ability |
| 2 | Strong through-put. The pump can persistently discharge gravel, high plastic soil lump and so on |
| 3 | The pump can be directly matched with either motor or diesel engine |
| 4 | Wide application. It can be used in various kinds of soil quality. |
| 5 | Little hydraulic loss, high efficiency and low oil-consumption |
| 6 | Little volume, light weight |
| 7 | Steady operating, little vibration, low noise |
| 8 | Simple & reliable construction, easily disassembly & assembly, convenient maintaining |
| 9 | Reliable sealing without leakage |
