The KRS-series is a submersible three-phase cast iron high volume heavy-duty drainage pump driven by a 4-pole motor. The cast iron body, combined with the low speed motor, presents extra durability for use in the most demanding conditions. The top discharge, side flow design assures efficient motor cooling even when it operates with its motor exposed to air.* Model KRS1022 is a top discharge, flow-thru design. The top discharge, flow-thru design provides maximum motor cooling efficiency allowing continuous operation at low water levels and extended dry-run capability.
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.
A stone quarry in Germany faced the task of relocating water, essential to its operations, from an intermediate sump to the ultimate discharge point. Overcoming approximately 400 meters, the quarry employed a Tsurumi KRS 65.5 booster pump, delivering an effective solution to the customer's needs. Tsurumi's cutting-edge design enables their pumps to excel even when not submerged, enhancing their versatility and enabling uninterrupted operation in challenging applications.
