Submersible Extra High Head Pump www.tsurumi-global.com Max. 230m head and excellent durability, optimum for high head applications. extra high head pump is equipped with duplex impellers that deliver a maximum head of over 200m. The upper impeller is attached in the reverse direction of the lower impeller (back-to-back), and reduces thrust load and enhances the durability of bearings. High-chromium cast iron is used for the impellers and mouth ring, to ensure wear resistance. The labyrinth ring and shaft sleeve are made of 630 stainless steel that is superior in wear resistance and strength to other stainless steels, to provide a perfect countermeasure against wear caused by high pressure generated in the casing. Additionally, the pump is equipped with seal pressure relief ports that release pump pressure applied to the mechanical seal. The flow-thru discharge design of the pump forcibly cools the motor so as to endure even extended operation at low water level. Amenities from Technology for People and the Earth 1 Anti-wicking Cable Entry 2 Prevents water incursion due to capillary wicking should the power cable be damaged or the end submerged. 3 React to excessive heat caused by dry-running. The bimetal strip opens to cause the control panel to shut the power supply. Dual Inside Mechanical Seal 4 Eliminates problems like spring failure and ensures a long service life. Isolated in the oil chamber where a clean, non-corrosive and abrasion-free lubricating environment is maintained. 5 Leakage Sensor 6 Oil Lifter (Patened) Seal Pressure Relief Ports Protect the mechanical seal from pump pressure. They also protect the seal face by discharging wear particles. Dual Back-to-Back Impellers 8 Reduce the thrust load applied to the impellers and enhance bearing endurance. Protect the pump against corrosive potential generated during the drainage of wastewater.

Detects flooding into the oil chamber that may occur in a worst case scenario. When flooding is detected, signals are sent to operate the indicator lamps through the external control panel. 7 Miniature Thermal Protector Total Head (m) 1 0 0 0.2 0.4 0.6 0.8 1.0 1.2 1.4 1.6 1.8 2.0 2.2 Capacity (m3/min) Motor 100mm, JIS 20kg/cm Flange Closed ( Dual) / High-chromium Cast Iron Output 110kW, 2-pole Impeller Phase Three Mouth Ring High-chromium Cast Iron Type Dry-type Submersible Induction Motor Labyrinth Ring 630 Stainless Steel Casing Gray Cast Iron Miniature Thermal Protector Leakage Sensor Shaft Seal Double Mechanical Seal (with Oil Lifter) / Silicon Carbide Protection Device ( Built-in ) Cable Shaft Sleeve 630 Stainless Steel Galvanic Anode Aluminium Alloy Discharge Bore & Connection 2 20m / Chloroprene Rubber Measurement Dimensions L x W x H Dry Weight ( excluding Cable ) 616 x 592 x 1825mm 1270kg We reserve the right to change the specifications and designs for improvement without prior notice.
