Tsurumi Manufacturing Co., Ltd. was founded in Japan in 1924, and has since been engaged in the manufacture, purchase and sales of various pumps, environmental equipment and peripherals -- submersible pumps are key products. Tsurumi offers pumps for various liquids including those difficult to handle, such as seawater, corrosive liquids and high temperature liquids, as well as pumps for general wastewater. Here, we introduce our "submersible pumps for high temperature liquids." Tsurumi manufactures submersible pumps that can drain high temperature liquids of up to 90°. There are many applications that need such drainage capability, e.g., draining hot spring water from mines located in volcanic zones, or draining industrial wastewater from power plants or ironworks. Tsurumi's standard pumps can drain liquids of up to 40°C, while some models can handle liquids of 60°C to 90°C. These latter provide specifications suitable for the temperatures of the liquids they handle, i.e., high-grade insulation and high- quality rubber materials, and lubrication oil and bearing grease for coping with high temperature liquids. Targeting these markets, three types of pumps are available: the KTZ-series (for draining general wastewater), GPN-series (for draining slurry) and SFQ-series (for draining corrosive liquids). The KTZ-series is positioned amongst Tsurumi's general-purpose pumps as a flagship model, with their impellers made of high-chromium cast iron and heavy-duty structure. The GPN-series offers high-power slurry pumps equipped with an agitator, wherein the impeller, suction plate and agitator are made of high-chromium cast iron and the shaft is made of chromium molybdenum steel that provides excellent strength and hardness. The SFQ-series of pumps are for corrosive liquids, as the principal wetted parts are made of 316 stainless steel, while those parts that need consideration for wear resistance, such as the impeller and pump casing, are made of 316 stainless steel casting. Also, the SFQ-series can withstand liquids of pH values of 2 to 13, which includes strong acids. These pumps are equipped with an anti-wicking cable entry and inside mechanical seal with silicon carbide face, as standard features. Tsurumi gives first priority to designing pumps that ensure continuous duty for a long period of time, by providing reliability and durability that enable stable operation even under harsh environments. To order any of these models, contact an authorized dealer. * The OO series is indicated with our series code in this text.
