6x4D-G Booster Sand Pump and Gravel Dredging Pump

Tobee® TG6/4D Gravel Sand Pump is 100% interchangeable with 6/4D-G Gravel Dredge Pump. And the 6x4D-G Gravel Pump are made of high chrome alloy materials for further increasing component life.

6x4D-G Gravel Pump is designed specifically for continuous pumping of extremely aggressive slurries, with a wide particle size distribution. Capable of handling large particles at consistently high efficiencies results in low cost of ownership. The large volume internal profile of the casing reduces associated velocities further increasing component life.

Design Features:

• Horizontal, cantilevered, single-casing structure, centrifugal pump design.
• Wide passage, good performance of NPSH, Anti-wearing and anti-corrosion, high efficiency.
• Cylinder bearing assembly, grease lubrication, adjusting the distance between impeller and pump.
• Mechanical seal, expeller seal and packing seal for selection.
• Driving type: Direct connection, VFD, V-belt drive, gearbox drive, elastic coupling drive, fluid coupling drive.
• Easy installation, discharge outlet can be adjusted at any direction of 360°.

Tobee's G/GH series Gravel and Dredge Pumps are also called Tunneling Pump.

Tunneling Slurry System

The slurry system consists of a closed pipeline loop which circulates the slurry mix through the head of the Tunneling machine where excavated materials are ground up and picked up into suspension, carried out of the tunnel and deposited into settling tanks on the surface of the operation. The settling tanks help to dewater the slurry, thereby removing the solids, allowing the water to be recirculated back into the Tunneling machine.

Assisted by Slurry Pumps

Slurry pumps help with slurry system circulation to and from the slurry separation location. Slurry feed pumps assist with slurry feed flow above the jacking shaft assisted by booster pumps with slurry return flow from the Tunneling Boring Machine (TBM), while the mid pumps aid the booster pumps on extended length drives and slurry return pumps assist with slurry return flow from the jacking frame to the slurry separation location. All slurry pumps are VFD driven for variable flow volumes depending on the project specifications.
