Tobee® TG6x4D Tunnel Gravel Pumps are a kind of sepecial pump including Feed pump, Discharge pump and Booster pump for MTBM, TBM, EPB, Slurry Shields, and Segment Shields in Tunnelling project, It is designed for continously handling the most difficult higher abrasive slurries which contain too big solids. TG6x4D tunnel Pumps are widely used for delivering gravels, slurries, sands, bentonite, sandy soil, rock, stone, sludge, mud etc
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°.
