submersible cutter pumps for sewage and wastewater, which are made of castings and equipped with cutting mechanism. Featuring a combination of impeller vane with brazed sintered tungsten carbide alloy edge and a suction cover of serrated shape, the C-series pumps enable smooth pumping, while cutting fibrous foreign objects during suction. These pumps have been used to drain sewage and wastewater from buildings and kitchens, and to transfer sewage and wastewater in water treatment facilities of factories and commercial complexes.

The C-series comes in a wide product lineup, covering discharge bore diameters of 50 to 200 mm and motor outputs of 0.75 to 37 kW. Among the C-series pumps, “CR” models are available as highly-durable cutter pumps, whose impeller and suction cover are made of high-chromium cast iron as a standard feature. All models of the C-series can be used in combination with a guide rail fitting device that enables easy installation and maintenance. In addition, a new model of dry pit type is optionally available. The dry pit type pump can be installed indoors, and outside a tank. With Tsurumi’s original specifications for dry pit, the dry pit pump delivers the performance of conventional submersible pumps in a variety of sites.

These pumps integrate original technologies that Tsurumi has researched and proven in the field over many years, such as anti-wicking cable, dual inside mechanical seals with silicone carbide face and Oil Lifter, etc. Furthermore, durability and wear resistance have been thoroughly considered in their design, so these pumps enable continuous duty over long periods of time.
Tsurumi products are designed to provide excellent durability and sound quality, thus contributing to the stable operation of facilities and enabling a considerable reduction in maintenance cost.
