Product Description

Tsurumi's KRS/KRD-series of submersible heavy-duty pumps are designed and built to handle high volume pumping jobs. The series offers three types of pumps: a basic (standard) type that is available in a wide product lineup, an energy-saving type of low output and low head that reduces power consumption, and a slurry dewatering type that is equipped with a high-chromium cast iron impeller and agitator. Also offered are KRSU-series submersible pumps for bypassing sewage in sewer renewal work, which optionally come in a flange connection type for countermeasures to floods. Furthermore, after many years of research and application, Tsurumi has an optional seawater-resistant version that can draw and drain seawater over extended periods of time. All in all, KRS/KRD-series pumps are of multiple-purpose build and widely applicable.

KRS/KRD-series pumps are available in a broad product lineup with discharge bore diameters of 80 to 250 mm, and motor outputs of 2.2 to 22 kW. All models integrate original technologies that Tsurumi has over the years researched and proven in the field, including Tsurumi's original anti-wicking cable, dual inside mechanical seals with silicon carbide faces and Oil Lifter, etc. Tsurumi pumps have and continue to play an active role in a wide range of applications, covering civil engineering and construction work that requires high reliability, large-scale construction projects such as tunnels, bridges and dams, and infrastructure for provisional drainage of sewage, simplified rainwater drainage for flood countermeasures, etc.
