The KTZ-series is a submersible three-phase cast iron high head heavy-duty drainage pump. The cast iron body with high-chromium cast iron impeller enables it to withstand demanding conditions found in construction, aggregate and mining applications. The top discharge, side flow design assures efficient motor cooling even when it operates with its motor exposed to air. The slim design allows the pump to be placed in a confined space. The discharge direction is selectable between vertical and inclined, which prevents folding or bending of the discharge hose. The pump with 7.5 to 22kW motor incorporates seal pressure relief ports that prevent the pumping pressure from applying to the shaft seal.
Tsurumi was contacted by SUEZ company to support with the decontamination of the soils of the former FORD site in Bordeaax, where they manufactured gearboxes for trucks and cars. The grounds were heavily polluted with oil and hydrocarbons that mixed with water and sand. Furthermore, there were limitations to the piping available, hence pumps had to be selected carefully. However, the biggest challenge was that every cleaning cycle, once started, had to finish as a malfunction would cause additional work.
New shafts were being excavated for the expansion of the underground mine in Serbia. Contractors in charge of the project used submersible pumps of other brands but had very bad experiences with too short lifespan of the pumps due to the heavy abrasive medium that has been pumped.
Skanska, one of the largest construction groups in the world, was looking for reliable pumps for a water cavern project.
In Sweden, a company had issues in one its main production processes: heating extracted ore to extremely high temperatures, just shy of its melting point. Following this heating process, the ore undergoes cooling. During the process residual water needs to be pumped which can be a challenge as well. The temperature of the residual water reaches up to 60 degrees celcius. As an added hardship the water is also loaded with abrasive ore particles.
A tunnel in Southern Germany with a length of 4300 meters is planned to be finished and operable by 2028. The biggest challenge for the project had been the need for lowering of the groundwater table in order for the tunnel boring machine to commence its work. The removed water needed to be treated for environmental requirements so it can be released for seepage into the nature.
In Germany quarrying for trap rock got difficult when explosives got involved. At the quarry dynamite was used to remove trap rock from the surrounding grounds. During this process the vaulable trap rock falls into the middle of the axcavation pit which is filled with water. In order to recover the product, the groundwater containing sand and crushed rock needed to be lowered.
