Tsurumi's flagship KTZ series submersible drainage pumps are engineered to tackle a wide range of demanding dewatering needs. This series now includes two powerful new 22 kW models—the KTZ422 (4-inch) and KTZ622 (6-inch)—further expanding the lineup from 1.5 kW to 22 kW. These pumps offer impressive performance with a maximum head of 72.5 meters and a maximum flow rate of 4 cubic meters per minute.
Constructed with a robust cast iron pump body and a high-chrome cast iron impeller, the KTZ series exhibits exceptional durability against wear and harsh environments. The unique top-discharge, side-flow design not only results in a slimmer pump body for easier installation in confined spaces but also ensures stable, long-term operation even under low water level conditions.
As an extremely reliable and durable heavy-duty pump, the KTZ series is the ideal choice for your operations in harsh conditions such as mines, quarries, construction sites, and tunnel projects. Tsurumi's exclusive multi-directional hose connection allows for simple operation, enabling flexible adjustment of the discharge direction (vertical or tilted) on-site with just a wrench, significantly enhancing field work convenience and efficiency.
1. Multi-directional Hose Connection
Flexible setting for tilted or vertical discharge, greatly simplifying on-site installation and improving efficiency.
2. Anti-wicking Cable Core
Effectively prevents water from entering the motor via capillary action, even if the cable sheath is damaged or the end is submerged. It also prevents humid air from entering the motor housing, avoiding condensation issues caused by temperature differences.
3. Dual Mechanical Seals with Silicon Carbide Surface
Seals are isolated from the oil chamber, ensuring a clean, non-corrosive, and wear-free lubrication environment. Compared to water-cooled external seals, this significantly reduces the risk of failure due to dry running and adhered substances. Silicon carbide offers 5 times the corrosion resistance, wear resistance, and heat resistance of tungsten carbide.
4. Oil-lubricated Agitator
Tsurumi's original design effectively provides lubrication and cooling for the seal faces even when the oil level drops to one-third of the normal level, ensuring stable shaft seal performance and extending seal life.
5. Seal Pressure Relief Port
Effectively protects the mechanical seal from internal pump pressure and allows for the discharge of wear particles, further safeguarding the integrity of the seal faces.
6. High-Chrome Cast Iron Semi-Open Impeller
Excellent wear and corrosion resistance, effectively resisting abrasion from solid particles, ensuring the pump maintains its initial performance over time and extending its service life.
