Tobee® WN Dredge Pumps are single-stage single suction cantilever horizontal centrifugal pumps with advantages of light weight, good wear-resistan, super dredging performance, WN dredging pumps impeller passage is very wide, It can continuously transport gravels or high plastic clay and not happens jam, Especially for dredging sands and damming of the river and seas.
WN Series Dredge Pumps can be also integrated with the gearbox, That mean the pump and gear box share one common shaft. So It dosen't need the pump bearing aseembly and frame, In this way, Not only save space, but also reduce cost and breakdown ratio, Let the dredge pump give play to maximum effectiveness.
Design Features:
• Single-stage single suction cantilever horizontal centrifugal dredge pump design
• Advanced CFD hydraulic model, wide passage , good NPSH performance, large dredging capacity
• Small water conservancy loss, high efficiency, low power consumption
• Anti-wearing and anti-corrosion materials(KmTBCr27), Hardness can upto 65HRC
• Reliable structure design,steady operating, little vibration, low noise
• Strong digging deep ability. It can suck the sands,slurries,gravels in underwater more than 20m depth.
• Excellent shaft sealing design without any leakages
• Simple structure and convenient installation,disassembly,maintenance
