12 / 10 G-G Single Suction Large Flow Sand Gravel Pump For Dredger
Dredging, Dredging Rivers
Product Introduction
The G Series Single Suction Large Flow Sand Gravel Pump is a
horizontal, single pump shell centrifugal slurry pump. The pump
clamp and the pump cover are clamped by special clamps. The
discharge direction of the pump can be installed at any position of
360 degrees.
The 12 / 10 G-G Single Suction Large Flow Sand Gravel Pump is made
of high-hardness wear-resistant alloy cast iron, KmTBCr26, which
can be adjusted according to industrial and mining conditions.
The12 / 10 G-G Single Suction Large Flow Sand Gravel Pump has a
wide flow path, good cavitation performance, high efficiency and
wear resistance. It is mainly used for continuous conveying of
strong abrasive materials that cannot be transported due to the
large size of the slurry.
The 12 / 10 G-G Single Suction Large Flow Sand Gravel Pump is
suitable for dredging, sand absorbing, dredging, river sand mining
and metal smelting.
Application fields
1. Draining sand from rivers, lakes, seas and reservoirs,
reclaiming land from the sea, extracting iron ore, and scouring
sand.
2. It is suitable for extracting a variety of yellow sand, mineral
sand, industrial and mining enterprises to transport tailings
slurry, tailing sand mine, slurry, slag, electric fly ash transport
and other strong abrasive media.
3. It is widely used in pebble and large particles, and has a large
environment for pump over-current capability: river, lake, sea,
reservoir, sand pumping, large particles, river dredging, high lift
and other construction environments, suitable for dredging Mud,
shale, pebbles, mining and metal smelting waste transportation.
