Product catalog summary

Overview: The document provides detailed information on Tsurumi's GSZ and GSD series of submersible high volume dewatering pumps. These pumps are designed for heavy-duty applications, offering high volume discharge and durability in challenging environments.

Specifications: The GSZ series includes models with 4-pole and 6-pole motors, designed for high head and high volume applications, respectively. The GSD series is a high-powered slurry pump with a 4-pole motor, featuring a high-chromium cast iron agitator for effective sediment handling. Motor outputs range from 22 to 150 kW.

Design Features: The pumps feature a side discharge spiral design for smooth passage of solids, and a water jacket for motor cooling. High-chromium cast iron and 304 stainless steel components provide wear resistance. Additional features include anti-wicking cable entry, air release valves, and dual inside mechanical seals with silicon carbide faces.

Options and Variants: Optional seawater-resistant versions are available, equipped with galvanic anodes and special impellers. High temperature liquid versions can handle up to 60°C. The GSZ-4 and GSZ-6 models are tailored for different operational needs, with the GSZ-6 capable of handling slurries with particulate matter.

Performance and Maintenance: The pumps are designed for continuous duty with features like seal pressure relief ports and an oil lifter to enhance seal life. The GSD series includes an agitating mechanism to assist in pumping sediments. Performance curves indicate the capacity and total head for various models, emphasizing the importance of not operating continuously along the dashed curve.

Applications: These pumps are suitable for civil engineering, construction, mining, and large-scale infrastructure projects like tunnels, bridges, and dams, where high reliability and durability are critical.

Tsurumi GSZ and GSD series of submersible heavy-duty pumps deliver high volume discharge. This former consists of the GSZ-4 (4-pole motor) that fully demonstrates the high head performance and the GSZ-6 (6-pole motor) that can discharge slurries laden with silt, earth, sand or other particulate. The Gsd is a slurry pump, built with a high-chromium cast iron agitator. With extensive lineups featuring motor outputs of 22 to 150kW, these pumps are used in a wide range of fields from civil engineering and construction projects that demand high reliability to mining and large-scale works for building...

Tsurumi hones its pump design in consideration of product characteristics. For example, because of the high head they deliver, the GSZ-4 and GSD have seal pressure relief ports that release pump pressure applied to the mechanical seal. Similarly, the GSZ-6 and GSD have impellers, suction plates and mouth rings made of high-chromium cast iron in order to defend against incoming wear-causing substances. And, if these parts wear down, the pumps maintain their original performance owing to an original mechanism that continuously adjusts the clearance between the parts.

High head, high volume drainage pumps with internal 4-pole motor The GSZ-4-series is a submersible three-phase cast iron high head and high volume heavy-duty drainage pump driven by a 4-pole motor. The side discharge, spiral design allows smoother passage of the sucked solid matters. The motor is cooled by a water jacket that assures efficient motor cooling even when it operates with its motor exposed to air. The pump incorporates seal pressure relief ports that prevent the pumping pressure from applying to the shaft seal. The GSZ-6-series is a submersible three-phase high power and high volume...
