The coronavirus pandemic is under control, the environment is not. It is time for the upcoming IFAT 2022 exhibition in Munich/Germany. Heavily improved top-of-the-line models in several series will be on display by pump manufacturer Tsurumi at stand B1.444 (Figure 1).
The new LSC2.75S residue dewatering pump is a 36 % more powerful version of the popular LSC1.4S. Now with 750 W of motor output, the shallow suction pump, which is only 37 cm high, moves water with 228 l/min or up to a height of 15 m. From level ground (buildings, containers, etc.) the pump extracts water down to a residual height of 1 mm. It is not necessary to monitor the pumping process. No water runs back when the pump is lifted. Thanks to the narrow housing, the new LSC even fits through a 200 mm pipe.
With the HS3.75SL, the manufacturer is launching a new multipurpose pump for heavy dewatering tasks. Its spiral watercourse is known from the “ultra-hard” concrete pumps. Even chunky lumps can be channelled through without immediately grinding down the internal components. With only 750 W of motor output, it achieves 580 l/min or 11 m delivery head. The pump is the new top model in the HS series, one of Tsurumi’s best-selling pump lines.
The GPN837 has been designed with a lot of attention to detail. It helps removing water with a lot of sand or mud. Compared to its predecessor, the throughput has been doubled to 9,000 l/min. An agitator mixes the pumping medium to make it more flowable. Even massive elements with a grain diameter of 30 mm cannot harm the new top-of-the-range unit. The maximum pumping height is 24 m.
Tsurumi also comes up with a novelty in the submersible aerators. The TRN-FL was developed for use in dissolved air flotation applications (DAF). For this purpose, the manufacturer has improved its basic design with regard to the gas bubble spectrum. Tsurumi achieved a higher air saturation through smaller bubble diameters.
On display at the stand will be numerous pumps from the 500-plus model range, which capacities up to 30 m3/min or 216 m head. The Japanese manufacturer is considered the world’s largest in its field. Technical achievements such as the maintenance-friendly modular design, individually encapsulated conductors and position-independent lubrication stand for long service lives. Cutaway models and live pump operation in the large test basin allow visitors to see how everything works. The options for control and monitoring in the network are manifold, for which a complete system has been set up with “Tsurumi Connect”.
