For the first time Tsurumi will present their new cutting impeller pumps (Fig.) from the series C-CR at the IFAT ENTSORGA 2010. The new pumps are equipped with a two-pole instead of a four-pole motor. Thus, the speed of the impeller was increased from 1450 to 2850 rpm. The maximum delivery head has been increased to 47 m with the most powerful of the seven new models. Also with the new series Tsurumi relies on the technology of the C series, which is still manufactured. In particular, the patented oil distributor should be mentioned, which has contributed to the extremely long life of the Japanese pumps. This and the low-maintenance design make this pump an all-rounder for wastewater. A further highlight will be a submerged aerator for the oxygenation of biological purification plants. These devices are an alternative to the expensive diaphragm aerators, which are susceptible to faults and which are often not suitable for small and medium purification plants. With the series TRN Tsurumi presents virtually maintenance-free submerged aerators, which bubble up to 630 m³/h of air into the basin and which are suitable even for mobile sewage plant operation.
