A leading civil engineering company in the Netherlands has recently contracted a Tsurumi dealer, Distrimex Pompen & Service, for their ‘Hamburg Underground Construction Pit’ project, requiring a submersible pump for heavy duty dredging applications. The chosen Tsurumi LH 8110 submersible pump features an eight inch high pressure pump with an output of 110 kW. The LH 8110 is the largest Tsurumi pump ever delivered from the Netherlands.
The Tsurumi LH 8110 provides 10 bars of pressure at a capacity of over 190 m³/hr. As with all Tsurumi submersible pumps, the dual mechanical seals operate in an oil chamber, additionally lubricated by a patented oil-lifter. The pump is complete with a chromium iron casting impeller and adjustable wear rings, guaranteeing increased wear resistance. Seal pressure relief ports provide a flow path above the pump casing and allow pressure to release from the pump casing and away from the shaft.
The ‘Hamburg Underground Construction Pit’ project involves excavating approximately 120,000 m³ for the Hamburg underground train line by the end of February 2016.
